120 Koenigsberg was a light unarmoured cruiser of about 3,400 tons displacement11, and was laid down in December 1905. She carried an armament of ten 4.1-inch guns, and was protected by a 2-inch armoured deck. The Germans had begun the construction of vessels12 of this class about seven years before with Gazelle, which was followed in the next year by Niobe and Nymphe, and then by four more—including Ariadne, destroyed by Lion in the affair of the Heligoland Bight—which were laid down in 1900. Two years later came the three Frauenlobs, and the Bremen class—five in number—succeeded these in 1903–4. In 1905 followed Leipzig, Danzig, and finally the ship that concerns us to-day. All these vessels had the same armament, but in the six years the displacement had gone up 1,000 tons. The speed had increased from 21? knots to about 24, and the nominal15 radius16 of action by about 50 per cent. Koenigsberg was succeeded by the Stettins in 1906–7, the two Dresdens in 1907–8, the four Kolbergs in 1908–9, and the four Breslaus in 1911. Karlsruhe, Grodenz, and Rostock were the only three of the 1912–13 programmes which were completed when the war began. The process of growth, illustrated17 in the advance of Koenigsberg over Niobe, was maintained, so that in the Karlsruhe class in the programme of 1912, while the unit of armament is preserved, we find that the number of guns had grown from ten to twelve; the speed had advanced from 23? to 28 knots, and the displacement from 3,400 to nearly 5,000 tons. As we know now, in the Battle of Jutland we destroyed light cruisers of a still later class in which, in addition to every other form of defence, the armament had been changed from 4.1-inch to 6.7 guns.
Koenigsberg, on the very eve of the outbreak of war, was seen by three ships of the Cape18 Squadron off Dar-es-121Salaam, the principal port of German East Africa. She was then travelling due north at top speed, and was not seen or heard of again until, a week later, she sank the British steamer City of Winchester near the island of Socotra. There followed three weeks during which no news of her whereabouts reached us. At the end of the month it was known that she had returned south and was in the neighbourhood of Madagascar. At the end of the third week in September she came upon H.M.S. Pegasus off Zanzibar. Pegasus was taken completely unawares while she was cleaning furnaces and boilers19 and engaged in general repairs. It was not possible then for her to make any effective reply to Koenigsberg’s sudden assault, and a few hours after Koenigsberg left she sank. Some time between the end of September and the end of October, Koenigsberg retreated up one of the mouths of the Rufigi River, and was discovered near the entrance on October 31 by H.M.S. Chatham. From then onwards, all the mouths of the river were blockaded and escape became impossible. Her captain seemingly determined20, in these circumstances, to make the ship absolutely safe. He took advantage of the high water tides, and forced his vessel13 some twelve or more miles up the river. Here she was located by aeroplane at the end of November. Various efforts had been made to reach her by gunfire. It was asserted at one time that H.M.S. Goliath had indeed destroyed her by indirect bombardment. But there was never any foundation for supposing the story to be true, and if in the course of any of these efforts the ship suffered any damage, it became abundantly clear, when she was finally engaged by the monitors, either that her armament had never been touched, or that all injuries had been made good.
122 The problems which the existence of Koenigsberg propounded21 were: first, Was it a matter of very urgent moment to destroy her? Second, How could her destruction be effected? The importance of destroying her was great. There was, of course, no fear of her affecting the naval position seriously if she should be able to escape; but that she could do some, and possibly great, damage if at large, the depredations22 of Emden in the neighbouring Indian Ocean, and of Karlsruhe off Pernambuco, had proved very amply indeed. If she was not destroyed then, a close blockade would have to be rigidly23 maintained, and it was a question whether the maintenance of the blockade would not involve, in the end, just as much trouble as her destruction. Then there was a further point. Sooner or later, the forces of Great Britain and Belgium would certainly have to undertake the conquest of German East Africa. While Koenigsberg could not be used as a unit for defence, her crew and armament might prove valuable assets to the enemy. Finally, there was a question of prestige. The Germans thought that they had made their ship safe. If the thing was possible, it was our obvious duty to prove that their confidence was misplaced.
If the ship was to be destroyed, what was to be the method of her destruction? She could not be reached by ship’s guns. For no normal warship24 of superior power would be of less draught25 than Koenigsberg, and unless the draught were very materially less, it would be quite impossible to get within range, except by processes as slow and laborious26 as those by which she had attained27 her anchorage. Was it worth while attempting a cutting-out expedition? It would not, of course, be on the lines of the dashing and gallant28 adventures so brilliantly drawn29 for us by Captain Marryat. The boats would proceed under123 steam and would not be rowed; they would not sally out to board the enemy and fight his crew hand to hand, but to get near enough to start a torpedo30 at him, discharged from dropping gear in a picket31 boat. To have attempted this would have been to face a grave risk, for not only might the several entrances be mined, but the boats clearly would have to advance unprotected up a river whose banks were covered with bush impenetrable to the eye. The enemy, it was known, had not only considerable military forces in the colony, but those well supplied with field artillery32. And there were on board Koenigsberg not only the 4.1-inch guns of her main armament, but a considerable battery of eight or perhaps twelve, 3-inch guns—a weapon amply large enough to sink a ship’s picket boat, and that with a single shot. An attack by boats then promised no success at all, for the excellent reason that it would be the simplest thing on earth for the enemy to defeat it long before the expedition had reached the point from which it could strike a blow at its prey34.
There was then only one possible solution of the problem. It was to employ armed vessels of sufficient gun-power to do the work quickly, and of shallow enough draught to get to a fighting range quickly. If the thing were not done quickly, an attack from the masked banks might be fatal. If the guns of such a vessel were corrected by observers in aeroplanes, they might be enabled to do the trick. Fortunately, at the very opening of the war, the Admiralty had purchased from the builders three river monitors, then under construction in England for the Brazilian Government. They drew but a few feet. Their free board was low, their centre structure afforded but a small mark; the two 6-inch guns they carried fore14 and aft were protected by steel shields. They had been employed124 with marked success against the Germans in their first advance to the coast of Belgium. When the enemy, having established himself in the neighbourhood of Nieuport, had time to bring up and emplace long-range guns of large calibre, the further employment of these river monitors on this, their first job, was no longer possible. For the moment, then, they seemed to be out of work, and here was an undertaking35 exactly suited to their capacity. It was not the sort of undertaking for which they had been designed. But it was one to which, undoubtedly36 they could be adapted. Of the three monitors Mersey and Severn were therefore sent out to Mafia Island, which lies just off the Rufigi Delta and had been seized by us early in the proceedings37.
The first aeroplanes available proved to be unequal to the task, because of the inadequacy38 of their lifting power. The atmosphere in the tropics is of a totally different buoyancy from that in colder latitudes39, and a machine whose engines enable it to mount quite easily to a height of 4,000 or 5,000 feet in Northern Europe, cannot, in Central Africa, rise more than a few hundred feet from the ground. New types of machines, therefore, had to be sent, and these had to be tested and got ready for work. For many weeks then, before the actual attack was undertaken, we must picture to ourselves the Island of Mafia, hitherto unoccupied and indeed untouched by Europeans, in the process of conversion40 into an effective base for some highly complicated combined operations of aircraft and sea force. The virgin41 forest had to be cleared away and the ground levelled for an aerodrome. The flying men had to study and master machines of a type of which they had no previous experience. The monitors had to have their guns tested and their structural42 arrangement altered and strengthened125 to fit them for their new undertaking. And indeed preparing the monitors was a serious matter. The whole delta of the Rufigi is covered with forest and thick bush—nowhere are the trees less than sixty feet high, and in places they rise to nearly three times this height. To engage the Koenigsberg with any prospect43 of success, five, six, or seven miles of one of the river branches would certainly have to be traversed. There was, it is true, a choice of three mouths by which these vessels might proceed. But it would be almost certain that the different mouths would be protected by artillery, machine guns, and rifles, and highly probable that one or all of them would be mined. The thick bush would make it impossible for the monitors to engage any hidden opponents with sufficient success to silence their fire. And obviously any portion of the bank might conceal44, not only field guns and riflemen, but stations from which torpedoes45 could be released against them. It was imperative46 therefore, to protect the monitors from such gun fire as might be encountered, and to take every step possible to preserve their buoyancy if a mine or torpedo was encountered.
The Trent had come out as a mother ship to these two unusual men-of-war, and from the moment of their arrival, she became an active arsenal47 for the further arming and protection of her charges. Many tons of plating were laid over their vulnerable portions—the steering48 gear, magazines, navigating49 bridges, etc., having to be specially50 considered. The gun shields were increased in size, and every precaution taken to protect the gunners from rifle fire. Where plating could not be added, sandbags were employed. By these means the danger of the ship being incapacitated, or the crew being disabled by what the enemy could do from the bank, was reduced126 to a minimum. These precautions would not, of course, have been a complete protection against continuous hitting by the plunging51 fire of Koenigsberg’s artillery. The more difficult job was to protect the ships against mines and torpedoes. Their first and best protection, of course, was their shallow draught. But it was not left at that; and most ingenious devices were employed which would have gone a fair way to keep the ships floating even had an under-water mine been exploded beneath the bottom. At intervals53, between these spells of dockyard work, the monitors were taken out for practice in conjunction with the aeroplanes. Mafia Island, which had already served as a dockyard and aerodrome, was now once more to come in useful as a screen between the monitors and the target. The various operations necessary for indirect fire were carefully studied. Gun-layers, of course, cannot aim at a mark they cannot see. The gun, therefore, has to be trained and elevated on information exteriorly55 obtained, and some object within view—at exactly the same height above the water as the gun-layer—has to be found on which he is to direct his sight. The gun is now elevated to the approximate range, a shot is fired and the direction of the shot and the distance upon the sight are altered in accordance with the correction. At last a point of aim for the gun-layer, and a sight elevation56 and deflection are found, and his duty then is to fire away, aiming perhaps at a twig58 or a leaf a few hundred yards off, while the projectile59 he discharges falls upon a target four, five, or even six miles off.
THE FIRST ATTEMPT
At last all was ready for the great attack. The crew had all been put into khaki, every fitting had been cleared127 out of the monitors; they had slipped off in the dark the night before and were anchored when, at 3:30 in the morning, all was ready. I will now let a participant continue the story:
“I woke up hearing the chatter60 of the seedy boys and the voice of the quartermaster telling someone it was 3:20. I hurried along to my cabin and was dressed in three minutes; khaki shirt, trousers, shoes, and socks. A servant brought me a cup of cocoa and some biscuits, and I then gathered the waterbottle and a haversack of sandwiches, biscuits, brandy flask61, glass phial of morphia, box of matches, cigarettes, and made my way up to the top.
“It was quite dark in spite of the half moon partly hidden by clouds, and men wandering about the docks putting the last touches. It was impossible to recognize any one as all were in khaki and cap and helmet. By 3:45 all were at general quarters and at —— we weighed and proceeded. Both motor-boats were towing, one on either side amidships. Two whalers anchored off Komo Island, and burning a single light each, acted as a guide to the mouth. We soon began to see the dim outline of the shore on the right hand, and —— declared he could distinguish the mouth. There were four of us in the top. We arranged ourselves conveniently, —— and —— taking a side each to look out. The Gunnery Lieutenant62 took the fore 6-inch and starboard battery. I had the after 6-inch and port battery. I dozed63 at first for about ten minutes, but as the island neared woke up completely. We had no idea what sort of reception we should have, and speculated about it. It was quite cold looking over the top. The land came nearer and nearer. We were going slow, sounding all the way. On the starboard side it128 was quite visible as the light grew stronger and stronger. Suddenly when we were well inside the right bank we heard a shot fired on the starboard quarter, but could not see the flash. Then came another, but only at the third did we see where it came from. It was a field-gun on the right, but we had already passed it, and both it and the pom-pom were turned on the Mersey astern of us.
“At least nothing fell near us. It was still not light enough for us to judge the range, but as the alarm had been given we opened fire with the 3-pounders, starboard side, at the fieldgun. As we came up to the point on the port side I trained all the port battery on the foremost bearing, and opened fire as soon as the guns would bear. We were now going pretty well full speed. Some snipers were hidden in the trees and rushes, and let us have it as we went past. The report of their rifles sounded quite different from ours, but we were abreast64 before they started, and were soon past. It was just getting light. We were inside the river before the sun rose, and went quite fast up. It was just about dead low water as we entered, neap tide. The river was about 700 yards broad. The banks were well defined by the green trees, mangroves probably, which grew right down to the edges. The land beyond was quite flat on the left, but about four miles to the right rose to quite a good height—Pemba Hills. Here and there were native huts well back from the river; we could see them from the top though they were invisible from the deck. On either side as we passed up were creeks66 of all sorts and sizes at low tides, more of them on the port side than on the starboard. As we passed, or rather before, we turned the port or starboard batteries on them and swept either side. The gun-layers had orders to fire at anything that moved or129 looked suspicious. We controlled them more or less, and gave them the bearings of the creeks. —— was in charge of those on deck, and the crews themselves fired or ceased fire if they saw anything or had sunk anything. We checked them from time to time as the next creek65 opened up. We were looking ahead most of the time, but I believe (from ——) we sank three dhows and a boat. Whether they were harmless or not, I don’t know, but it had to be done as a precaution. We made a fine noise, the sharp report of the five 3-pounders and one 4.7 and the crackle of the machine guns (four a side) must have been heard for miles. The Hyacinth, the tugs67, the Trent, the Weymouth, and other odd craft were demonstrating at the other mouths of the Rufigi, and we could hear the deep boom of their 6-inch now and then. I believe, too, that there was a demonstration68 by colliers, etc., off Dar-es-Salaam at the same time.
“I had thought that the entry would be the worst part, but it was not much. A few bullets got us and marked the plates or went through the hammocks but no one was hit, and as our noise completely drowned the report of their rifles I doubt if many knew we were being sniped. The forecastle hands knew all about it later on. As they hauled in the anchor or let it go they nipped behind any shelter there was, and could hear the bullets zip-zip into the sandbags. The Mersey astern was blazing away into the banks just as we were. There was probably nothing in most of the creeks—but we did not know it then.
“It was 6:30 o’clock by the time we reached ‘our’ island, where the river branches into three, at the end of which we were to anchor. We were steering straight up the middle of the stream, and then swung slowly round to port, dropped the stern anchor, let out seventy fathoms130 of wire, dropped the main anchor, went astern, and then tightened69 in both cables, so that we were anchored fast bow and stern. As soon as we steadied down a bearing was taken on the chart and the gun laid—about eight minutes’ work. It was then found that, thanks to the curious run of the current, the fore 6-inch would not bear, and we had to take up the bow anchor and let it go again to get us squarer towards the Koenigsberg.
“We could see the aeroplane right high up, and received the signal ‘open fire.’ We were not quite ready, however. From the moment when we turned to port to take up our firing position to the time we were finally ready and had laid both guns, occupied about twenty minutes. The Koenigsberg started firing at us five minutes before we were ready to start. Their first shot (from one gun only) fell on the island, the next was on the edge of it, and very soon she was straddling us. Where they were spotting from I don’t know, but they must have been in a good position, and their spotting was excellent. They never lost our range. The firing started, and for the next two hours both sides were hard at it. I don’t believe any ship has been in a hotter place without being hit. Their shooting was extraordinarily70 good. Their salvoes of fire at first dropped 100 short, 50 over, 20 to the right—then straddled us—then just short—then all round us, and so on. We might have been hit fifty times—they could not have fired better; but we were not hit at all, though a piece of shell was picked up on the forecastle.
“The river was now a curious sight, as dead fish were coming to the surface everywhere. It was the Koenigsberg’s shells bursting in the water which did the damage, and there were masses of them everywhere—mostly small ones.
131 “We were firing all the time, of course. I attended to the W/T, and passed the messages to the Gunnery Lieutenant, who made the corrections and passed them to the guns. —— watched the aeroplane and the banks as far as possible. —— attended to the conning71 tower voice pipe. We got H. T. fairly soon, and the Koenigsberg’s salvoes were now only four guns. We heard the boom; then before it had finished came whizz-z-z-z or plop, plop, plop, plop, as the shells went just short or over. They were firing much more rapidly than we, and I should think more accurately72, but if I had been in the Koenigsberg I should, probably, have thought the opposite! All this time the 3-pounders had occasional outbursts as they saw, or thought they saw, something moving. Occasionally, too, the smoke and fumes73 from our funnel74 drifted across the top, and it was unpleasant for a minute or two. We could see now where the Koenigsberg was, and the smoke from her funnels75, or that our shells made. She was firing salvoes of four with great rapidity and regularity76, about three times a minute, and every one of them close. Some made a splash in the water so near that you could have reached the place with a boat-hook.
“At 7:40 (so I am told, as, though I tried I lost all count of time) a shell hit the fore 6-inch of the Mersey and a column of flame shot up. Four were killed and four wounded. Part of the shield was blown away. Only one man remained standing77, and after swaying about he fell dead. One had his head completely blown off. Another was lying with his arm torn out at the shoulder, and his body covered with yellow flames from a lyddite charge which caught. The R. N. R. Lieutenant in charge was knocked senseless and covered with blood, but had only a scratch on the wrist to show for it. The132 gun-layer had an extraordinary escape, and only lost three fingers. Two men escaped as they had just gone forward to weigh the anchor. A burning charge fell into the shell room below, but was fortunately got out. Another shell burst in the motor-boat alongside the Mersey and sank it. One burst in the water about a foot from the side, and we thought she was holed. The Mersey captain then wisely moved and went down river, taking up a position of 1,000 yards down, by the right bank (looking at the Koenigsberg). She started in again with her after gun, the other being disabled. For an hour and twenty minutes we went on, and the Koenigsberg’s salvoes came steadily78 and regularly back, as close as ever. It seemed as if it could not go on much longer. We registered four hits, and the salvoes were reduced from four to three, and later to two, and then to one gun. Whether we had reduced them to silence or whether the Koenigsberg’s crew left them and saved ammunition80 it is impossible to say.
“The aeroplane spotting had been fair, but now someone else started in and made the signals unintelligible81. Then we got spotting corrections from two sources—both differing widely. Finally, the aeroplane made “W. O.” (going home). We weighed and took up station again by the Mersey. She moved to get out of our way, and when another aeroplane came we started it again. The replies from the Koenigsberg were not so frequent, and nothing like so accurate. It was as if they could not spot the fall of shot. The aeroplane soon disappeared, and as we could see the mast of the Koenigsberg (I could only see one personally) and a column of smoke which varied82 in thickness from time to time, we tried to spot for ourselves. It was useless as, though we saw the burst133 (or thought we did) in line with the masts, we did not know whether they were over or short. Finally, we moved up the river nearer, still keeping on the right side, and set to work again.
“There were two cruisers—Weymouth and Pyramus, I think—at the mouth. The Weymouth did a good deal of firing at Pemba Hill and a native village close to us, where there might be spotters.
“When we reached W/T corrections now they were of no use. Most were ‘did not observe fall of shot,’ or 600 short. We went up 1,000, but still received the same signal—whether from the aeroplane or the Koenigsberg, I don’t know. It was most confusing. We crept up the scale to maximum elevation. Finally, we moved up the river again, but put our nose on the mud. We were soon off, and moved over to the other side and continued firing, spotting as well as we could (but getting nothing definite) till four o’clock, when we packed up and prepared to come out. We swept the banks again on both sides, but only at the entrance was there opposition83. We made such a noise ourselves that we drowned the report of any shots fired at us. Two field-guns made good practice at us from the right bank (looking at the Koenigsberg). One came very close indeed to the top—so much so that we all turned to look at each other, thinking it must have touched somewhere. One burst about five yards over us. Another burst fifteen yards from the Mersey, and a second hit her sounding boom. We could see the white smoke of the discharge and fired lyddite, but the object was invisible.
“It was getting dusk as we got outside at full speed. The secure was sounded at about 4:45. We had been at general quarters for thirteen hours, and eleven of them134 had been under fire. Outside the other ships were waiting for us near Komo Island, and we went straight alongside the Trent. Each ship cheered us as we passed. The Mersey put her wounded on the Trent, and then pushed off to bury the dead.
“Tuesday, July 6, was the day of the first attempt, and one of the worst I ever had or am likely to have. We were at our stations from 3:45 A.M. till 4:45 P.M., and eleven hours of that were under fire. The engine-room people were not relieved the whole time, and they were down there the whole time in a temperature of 132°-135°! It was hot up in the top—but child’s play to the engine room.”
SUCCESS
On July 11 the second attack was made, but made in a very different manner from the first. Once more let us allow the same writer to complete the story:
“We went to General Quarters at 10:40 A.M. and were inside the entrance by 11:40. How well we seemed to know the place! I knew exactly where the beastly field guns at the mouth would open fire and exactly when they would cease—as we pushed in, and so if their shots went over us they would land on the opposite bank among their own troops. Very soon came the soft whistle of the shell, then again and again—but we were nearing the entrance and they turned on the Mersey. They hit her twice, wounding two men and knocking down the after 6-inch gun crew—none was hurt, however. I spotted84 a boat straight ahead making across the river for dear life—they may only have been natives, but we fired the 6-inch at them till they leapt ashore85 and disappeared.
“Up the river we went. I knew each creek, and almost135 each tree, and as before we blazed into them just before we passed.
“We left the Mersey at the place where we anchored last time in the hope that she would draw the Koenigsberg’s fire and leave us a free hand. The Koenigsberg, however, fired one salvo at her and then for the rest of the day concentrated on us. She was plugging us for seventeen minutes before we could return her fire. The salvoes of four were dropping closer than ever if possible and afterwards almost every man in the ship found a bit of German shell on board as a souvenir. They were everywhere—in the sandbags, on the decks, round the engine room—but not a soul was even scratched!
“We went on higher up the river than last time and finally anchored just at the top of ‘our’ old island. As the after 6-inch gun’s crew were securing the stern anchor two shells fell, one on either side, within three feet of the side, and drenched86 the quarter-deck. It was a very critical time. If she hit us we were probably finished, and she came as near as possible without actually touching87. I had bet 5s. that she would start with salvoes of four guns, and I won my bet. They did not last long, however, once we opened fire. It was a near thing, and had to end pretty quickly one way or the other. We had received orders that she must be destroyed, and the captain, the night before, had told all hands assembled on the quarter-deck that we had to do it. We intended to go up nearer and nearer, and if necessary sight her. Of course we could not have gone through it—but there is no doubt that on the 11th it was either the monitors or the Koenigsberg.
“We had no sooner anchored and laid the guns (the chart proved to be one mile out in the distance from us136 to the Koenigsberg!) than the aeroplane signalled she was ready to spot. Our first four salvoes, at about one minute interval52, were all signalled as ‘Did not observe fall of shot.’ We came down 400, then another 400 and more to the left. The next was spotted as 200 yards over and about 200 to the right. The next 150 short and 100 to the left. The necessary orders were sent to the guns, and at the seventh salvo we hit with one and were just over with the other. We hit eight times in the next twelve shots! It was frightfully exciting. The Koenigsberg was now firing salvoes of three only. The aeroplane signalled all hits were forward, so we came a little left to get her amidships. The machine suddenly signalled ‘Am hit: coming down; send a boat.’ And there she was about half way between us and the Koenigsberg planing down. As they fell they continued to signal our shots, for we, of course, kept firing. The aeroplane fell into the water about 150 yards from the Mersey and turned a somersault; one man was thrown clear, but the other had a struggle to get free. Finally both got away and were swimming for ten minutes before the Mersey’s motor-boat reached them—beating ours by a short head. They were uninjured and as merry as crickets!
“We kept on firing steadily the whole time, as we knew we were hitting—about one salvo a minute. The Koenigsberg was now firing two guns; it is hard to be certain, as there was much to do and a good noise going on. Still, within seventeen minutes of our opening fire I noticed and logged it down that she was firing two. She may have been reduced to that before, but she never fired more after.
“In a very short time there was a big explosion from the direction of the Koenigsberg, and from then on she was never free from smoke—sometimes more, sometimes less;137 at one moment belching88 out clouds of black smoke, then yellow, with dull explosions from time to time. We kept on firing regularly ourselves, one salvo to the minute—or perhaps two salvoes in three minutes, but the gun-layers were told to keep cool and make sure of their aim. There was one enormous explosion which shot up twice as high as the Koenigsberg’s masts, and the resulting smoke was visible from our deck. The men sent up a huge cheer.
“For some time now we had had no reply from the Koenigsberg. At 12:53 I fancy she fired one gun, but I was not certain. She certainly did not fire afterwards. As our guns were getting hot we increased the range from 9,550 to 9,575, and later to 9,625—as when hot the shots are apt to fall short. Fine columns of smoke, black, white, and yellow, and occasional dull reports rewarded us, but we were making no mistake and kept at it. The aeroplane was not available, and we had no one to spot for us, remember; still we could see the K.’s masts from our foretop, and the smoke, etc., told its own tale.
“Another aeroplane turned up, and we now signalled the Mersey to pass on up stream and open fire nearer. She gave us a great cheer as she passed.
“We raised our topmast and had a look at the Koenigsberg. She was a fine sight. One mast was leaning over and the other was broken at the maintop, and smoke was pouring out of the mast as out of a chimney. The funnels were gone, and she was a mass of smoke and flame from end to end. We had done all the firing which had destroyed her. The Mersey only started afterwards. That was part of the plan. Only one ship was to fire at a time, and then there could be no possible confusion in the spotting corrections; it was a lesson we learned on the Tuesday before! We started. The Mersey was then to move up138 past her and fire for an hour and so on. Fortunately it was not necessary, and as it turned out would have been impossible. If we had gone on we should probably be there now! When the Mersey passed us she struck a bar about 1,000 yards higher up, and after trying to cross in two different places 100 yards apart, anchored for firing. There was only eight feet of water on the bar and the tide was falling. If we had got up we should probably have had to wait twelve hours for high tide, and probably the Germans would have annoyed us from the banks!
“The Mersey fired about twenty salvoes and made several hits, and as the aeroplane had signalled ‘O. K.’ (target destroyed) we prepared to leave the river. Before we went the Gunnery Lieutenant and myself went to the top of the mast to get a better view, and I took a photo of the smoke, resting the camera on the very top of the topmast! The Captain came up too, and there were the three of us clinging to the lightning conductor with one arm, glasses in the other, and our feet on the empty oil drum we had fixed89 up there as a crow’s-nest.
“Just as we were starting back we saw some telegraph poles crossing a creek behind us. It was undoubtedly the communication used by the German spotters. We let fly with everything and smashed them up. A pole is not an easy thing to hit, and I expect the destruction of those two cost the Government about ￡300 in ammunition.
“All the way down we swept the banks and made up our minds to knock out the field guns at the mouth if we possibly could. We tried our best, but I don’t think we touched them. They fired on us till we were out of range. They did not hit—but I saw one fragment about six inches by one inch picked up on the boat deck.
“Two tugs were waiting over the bar, and after giving139 us a cheer took us on tow to help us back to Trent. The Weymouth, with the Admiral on board, came round and then passed us at speed; all hands lined the ship and, led by the small white figure of the Admiral on the bridge, gave us three splendid cheers. It was one of the finest sights I have ever seen. We answered back—and what a difference there was to our cheers of Tuesday last. We made about three times the noise....
“I went to the Captain’s cabin for half an hour to copy out the notes I had taken. From the very first shot we fired I kept a record of every shot fired by the 6-inch guns, and all I could see or hear round about, writing something every minute, i.e. 12:37 2 guns. H.T. J.M. 12:38 2 guns. H.T. 12:38? (Koenigsberg firing 2). Column of smoke; aeroplane hit and coming down, etc.
“I ought to explain that ‘J.M.,’ ‘B.F.,’ ‘F.20,’ ‘G.15,’ ‘H.T.,’ and so on are signals from the aeroplanes. ‘H.T.’ means ‘a hit.’ In order to make sure of the right letters having passed the man shouts not ‘H.T.’ alone, ‘H. for Harry90, T for Tommy,’ and then there can be no confusion. The man at the voice pipe in the conning tower simply roared out ‘H. for Harry, T. for Tommy,’ each time it was signalled. Well, when I was making my copy in his cabin on the way back, the Captain came in for a moment. He leaned his hand quietly on my shoulder and with a huge sigh said, ‘If ever I live to have a son, his name shall be Harry Tommy!’ I firmly believe he meant it too, at the time!”
If the people in Severn and Mersey had had a narrow squeak91 for it, not once but a dozen times, from Koenigsberg’s salvoes, the spotting party in the aeroplane must have had just as exciting a time. And, as we have seen from the foregoing account, with them Koenigsberg was140 more fortunate. On July 11th everything was against Lieutenant Cull92, the first pilot to go up, and Flight-Sub-Lieutenant Arnold, who was acting93 as observer. To begin with it was a cloudy day, and the machine had to be kept dangerously low if the observer was to do his work. The aeroplane got over the target at about 12:20, while Mersey was firing hard. But this fire of the Mersey had nothing to do with the organized effort to destroy the enemy. It was merely a blind—an effort to get the enemy’s observer on land to deflect57 the fire on that ship on to Mersey, while Severn got ready for the real work. The aeroplane, therefore, paid no attention to Mersey’s fire and telegraphed no observations. Ten minutes later Severn opened fire and Mersey ceased. Mersey’s diversion did for a time bring Koenigsberg’s guns in her direction. But no sooner did Severn open fire than she got the full benefit of Koenigsberg’s salvoes of four, which followed each other at intervals of about a minute. Five minutes after Severn opened at 12:30, Koenigsberg’s salvoes began to straddle her. Nine minutes after Severn opened fire the aeroplane signalled first hit. And less than ten minutes after that Lieutenant Arnold telegraphed ‘We are hit; send boat.’ In point of fact, it is probable that the aeroplane’s engine had been slightly injured earlier. For, dangerously low as the machine had to fly at the beginning, it was found impossible to keep even at that height, and as it got lower and slower, it obviously became an easier mark for the Koenigsberg’s 12-pounders. At 12:46 a terrific bump was felt in the machine, and shortly afterwards the engine broke up with a rattle94 and a crash, and there was nothing for it but to start sliding down. Imagine the situation! The machine, between 3,000 and 4,000 feet in the air, nearly three miles from the monitors; the only possible141 hope of safety to make this long glide95 and then to land—if the bull may be permitted—in a narrow strip of river bordered by impenetrable bush—the bush dotted with lofty trees! If the machine missed the river and hit the trees, it was certain death wherever it landed. If it missed the trees and hit the river, there was palpably no safety unless it was within a very short distance of the monitors. For nowhere else did the pilot and observer stand the faintest chance of rescue. A situation more absolutely desperate could hardly be imagined.
It was certainly not one in which the seemingly doomed96 occupants could have been blamed if they had thought of their safety and of nothing else. But while the pilot was, quite properly, concentrating his attention on performing as nice a feat33 in flying as can be imagined, Flight-Lieutenant Arnold, content to leave this matter in the skilled hands of his comrade, continued imperturbably97 to carry on his duties.
Severn, having got the range, naturally continued firing. Flight-Lieutenant Arnold, having been sent up to observe, continued observing, and each shot that he observed, on what must have seemed his last glide to certain death, was signalled to the control parties on board the monitor. The gist79 of this was that six out of ten shots were hitting, and apparently98 were hitting steadily, but all were striking Koenigsberg in the bows. Arnold’s last achievement as an observer was to deflect this fire amidships and to the stern. And he had hardly succeeded before the ‘plane crashed into the water 500 yards from the Mersey. Mersey had her motor-boat ready and it was sent full speed to the rescue. Arnold had no difficulty in getting himself free, but Lieutenant Cull was not so fortunate. In the excitement of his task he had forgotten to loosen the straps142 that held his belt and feet, and was fairly under water before he realized his predicament. How he wrenched99 himself free of these impediments is somewhat difficult to understand, and it is not surprising that his apparel suffered somewhat severely100 from his efforts. When he came to the surface he found Arnold scrambling101 about the wrecked102 machine in search of him, and both were got safely into the boat. The machine, smashed and waterlogged in the river, was of course past saving, and there was nothing for it but to demolish103 it. Take it all in all, few prettier pieces of work in the air—whether we look at the flight craftsmanship104 of the thing, or the practical use that the last moments of flight were put to—have yet been recorded.
A PROBLEM IN CONTROL
There are several features in these operations that are of great interest. To begin with, the destruction of a ship by the indirect fire of another ship had not, so far as I know, been systematically105 attempted before. There was indeed a story of Queen Elizabeth having sunk a Turkish transport by a shot fired clean over the Gallipoli peninsula. In the case of the Queen Elizabeth’s victim the target was not only incredibly far off but actually under way. But this must be regarded as amongst the flukes of war, if indeed that may be called a fluke when the right measure had been taken to ensure success. Still, it was more probable that the attempt might be made a hundred times without a hit being made than that the first shot fired should have landed straight on the target. But here on the Rufigi the monitors had gone up after making ample preparations and after full practice, to achieve a particular object. It was to destroy a very small ship at143 a range which, for the gun employed, must be considered extraordinarily great. Ten thousand yards is relatively106 a longer range for a 6-inch gun than is, say, 18,000 for a 15-inch. But while in this respect the task proposed was extraordinarily difficult, there was one element present that would distinguish it from almost any other known use of naval guns. In engaging land forts, both on the Belgian coast and off Gallipoli, there had been ample experience with a stationary107 target engaged by a stationary ship. But here the firing ship was not only stationary in the sense that it was moored108, but was practically at rest in that it was lying in smooth water with no roll or pitch to render the gun-layers’ aim uncertain. The current did cause a certain veering109, but not a sufficient movement to embarrass laying. But if in this respect the conditions were easy, they were extraordinarily difficult in every other. The monitors, for instance, were as much exposed to Koenigsberg’s fire as was Koenigsberg to that of the monitors, and whereas Koenigsberg’s guns could be spotted from a position on shore the monitors’ fire had to be spotted by aeroplane. The whole of the operations of Severn and Mersey then were not only carried out under fire, but under an attack that on the second day as well as the first was extraordinarily persistent110 and extraordinarily accurate. That in the course of two days only one of our ships was hit, and that one only once, must be considered a curiosity, for so good were the gunnery arrangements of Koenigsberg that each monitor when under fire was straddled again and again by salvoes, and when not straddled had the 4.2 shells falling in bunches either just short or just over them. The explanation of her having failed to get more hits than she did, while ultimately Severn’s was completely effective, does not lie144 in any inferiority of skill, but almost entirely111 in the fact that the range, if exceptionally great for a 6-inch gun, was almost fabulous112 for a 4.2, and next that Koenigsberg was a much larger target than either Severn or Mersey. Koenigsberg was probably aground, and therefore showing from three to four feet more of her side than she would at sea. Monitors are a craft with a very, very low freeboard, with a comparatively small central house built up amidships. As a point-blank target Koenigsberg would probably be more than twice the superficial area that either Mersey or Severn would present. The contrast between them as virtual targets, that is, the target that would be presented to the shell as it descended113 from a height upon the ship, would not, of course, be so great, because the monitors were each of them wider than the German cruiser, but even as a virtual target the Koenigsberg was much more favourable114 for the British guns.
But the master difficulty of the situation was for the men on the spot, without previous experience of indirect fire, and unaided apparently by any advice from headquarters as to the result of service experiments elsewhere, to extemporize115 all the processes for finding and keeping the range of a target invisible from the ship. The two essential elements in these processes were (1) for the observer in the aeroplane to note where each shot fell, and (2) to inform the ship that fired it exactly what the position of the impact was, whether to the right or to the left, over or short, and an approximate measurement in yards of its distance from the target. No one of those concerned had ever engaged in any similar operation. The aviators116 had not only never carried observers to spot naval gunfire, they had none of them ever even flown in the tropics, where the conditions of flight differ altogether145 from those in more temperate117 zones. The observers were even more new to the work than the aviators. Apparently some of them had never been in flying machines before. They not only had to learn the elements of spotting, they had to become familiar with the means of sending communications. There seems at one time to have been considerable doubt as to the best means to employ for communication. The means would have to include not only a system of sending messages, whether by wireless118, by lights flashing a Morse code or otherwise, but the production of a code as well. When these points were settled, the preliminary practices of Mafia Island gave what appeared to be sufficient experience to show that right principles were being followed. Only when this practice had given satisfactory results was the first attempt of July 6th made.
In the course of that day’s firing the observers reported eight possible hits during the first phase of the firing, and none afterwards. Once or twice smoke was seen to issue from Koenigsberg and in the course of the day the number of guns in her salvo fell from five to three, and ultimately she was employing only a single gun. The monitors had fired approximately 500 rounds to obtain these hits, and had probably double this number fired at them. Opinions differed as to the result, but that some thought Koenigsberg had finally been destroyed is apparent from the character of the Rear-Admiral’s message to the Admiralty. Reflection, however, appears to have made it clear that Koenigsberg was very far indeed from being really out of action, and it became necessary to inquire why there should have been any uncertainty119 in the matter. The crux120 of the position was this. Fire had opened at seven in the morning and continued till nearly half-past four146 in the afternoon. But when the character of the messages transmitted by the observers came under critical examination, it seemed almost certain that no hits were made at all after the first hour. Every kind of explanation for so indecisive and disappointing a result was examined. It was disappointing because it had been shown that it was quite practical to make hits, and it seemed as if there must be something wrong if the hitting could not be continued. Every possible cause of breakdown121 was put under examination. Had there been anything wrong with the wireless transmitters in the aeroplanes? Had the receiving gear in the monitors broken down? Were the observers too inexperienced, hasty, or unreliable? Had the guns become worn or too hot? Were the sights at fault? But when it came to the point each of these criticisms broke down. There was no reason to distrust the observers, and as all the ships in the offing had received the messages, the transmitting gear must have been above suspicion. Then the monitors’ records tallied122 with the ships’ records, so that there was nothing wrong with the receivers. When the observers themselves were put through their paces, it seemed that over an area of at least half a mile, say 600 yards short of the target and 200 over, there was really no possibility of making mistakes about where the shots fell, for in this area it was all either open water or dry sand. But outside of this comparatively narrow area there was thick bush, and to an observer at the height of between 3,000 and 4,000 feet even a bursting shell falling in a forest whose trees ran from between 70 to 150 feet high, affords a very uncertain mark. And after 8 P.M. it seemed that only very few shells fell in the belt where their impact was visible, and that sometimes, for very considerable periods, every shot seemed to go into147 the forest. Could the guns have suddenly become absolutely unreliable? But tests were made, and the guns proved to be quite as accurate as they were before the firing began, and indeed the exactitude of the results precluded123 this form of error from explaining the failure to complete the business.
At last, when the firing times of the two ships were compared with the observers’ records of the pitching of the shell, the true explanation leapt into sight. The whole show had broken down over the old difficulty of the identification of shots. The people in the aeroplanes could not tell whether a particular shot had been fired by Mersey or Severn, and as both ships got the message, neither could tell whose shot had been observed. It followed therefore that the consequent correction was often put on to the wrong gun. Thus, for example, suppose Mersey had fired a shot 300 yards over the target that fell in bush and was invisible to the observers, while Severn had fired one that was 200 yards short and visible. The observers would wireless 200 short, whereupon the Mersey would think that this message was intended for her, and raise her sight by this amount. Her next round, of course, would go still farther into the bush, and suppose this was visible or partially124 visible to the observer, who might perhaps have missed Severn’s next round, he might telegraph back 500 or 600 over, a correction that Severn might take to herself, and lose her next shot in the bush short of the target. The men on the Rufigi in short discovered for themselves, by their experiences on this first arduous125 day against the Koenigsberg, that the problem of correcting the fire of two separated batteries by the work of a single observer is so exceedingly difficult of solution as to make it hardly worth attempting. The lessons so148 painfully brought home were put to immediate and most successful use. It was resolved on the second attempt that only one monitor should fire at a time. This was not of course the only experience of value obtained in the first day’s operation for when all the results were collated126 and compared, a pretty exact knowledge of the actual range from the chosen anchorage to the target was obtained, so that on the second day there were fewer initial rounds lost before shell began to fall in the immediate surroundings of the enemy, where the position of each could be verified. When all ambiguity127 as to the meaning of corrections was removed, the process of finding the target and keeping the range became exceedingly simple.
As will be seen from the narrative, the serious work of the second day began when Severn opened fire about half-past twelve. Nine minutes later, after quite deliberate fire, she obtained her first hit, and from then on continued hitting with great regularity. But before she had been firing ten minutes the spotting aeroplane was disabled and came down. Though the Koenigsberg herself was invisible, the columns of lyddite fumes and smoke sent up by the hits could be seen over the trees, and such columns indicated that hits were being made very frequently. Within a quarter of an hour of the first hit, Koenigsberg ceased her return fire, and shortly after this a huge volume of smoke of a totally different colour from that sent up by lyddite indicated that there had been a great explosion in the ship. When the second aeroplane came out to resume the work of spotting, Mersey took up the work of firing in Severn’s place. Severn had ceased fire at 1:35 and Mersey opened at a quarter past two. But it soon became clear that it was unnecessary for her to149 proceed with the work, and that with the explosion at 1:15 the business of the Koenigsberg was finished.
What two ships firing continuously for eight hours on July 6th had failed to achieve, a single ship had accomplished128 in probably fifteen minutes. It was the most perfect exemplification imaginable of the difference in results that wrong and right systems of gunnery produce. The skill shown on the second day was no better than on the first. It was a change of method that made the difference.
What is of special interest is this. Up to the year 1909 it appeared quite premature129 to discuss methods of concentrating the fire of several ships on a single distant target, until right methods had been discovered for making sure of hitting it with the guns of a single ship. But by the winter of 1909 there seemed to be sufficient experience to show that a complete solution of the simpler problem was assured, and that the time had come for considering how two or more ships could combine their armament. The difficulty of the matter was soon made obvious. While great guns do not all shoot exactly alike, it is possible to ascertain130 by experiment the individual differences of all the guns in a single ship, and to vary the sight scales so that, at all critical ranges, they should give identical results. But what can be done for a single battery of eight or ten guns cannot be done by experiment for two units of such batteries. If then two ships are to be employed at the same target, it was the very essence of the matter if two processes were carried on simultaneously131 to obtain one result, that each process should be so organized as to run as if the other were not going at all. Now ships’ guns at sea can be corrected only from positions high up in the masts. It therefore became clear150 that if the firing ship allowed a fixed interval, say three or four seconds, to elapse after a sister ship had fired, before sending her own salvo at the enemy, it would be quite easy, by keeping a record of the time of flight of the projectiles132, to pick out her own amongst the salvoes falling in rapid succession on the target, so that there should be no possibility of her mixing up her own shells with her neighbours’. It is now many years since it was suggested that gongs driven by a clockwork device, which could be set to the time of flight, would simplify this method of identification. Suppose the time of flight to be twelve seconds, the gong would be set to this interval and the clockwork started into motion simultaneously with the firing of the salvo. The observers watch the target and pay no attention to any shots that fall, except those whose incidence coincided with the ringing of the gong.
The essence of this system was the ear-marking, so to speak, of each separate salvo as it went away. But it was manifestly not a principle on which observers placed at a distance from a ship could work. If they were to do their work they must employ some totally different means of identification. Else indirect firing could only be carried on by one ship at a time.
My correspondence in 1909 and 1910 shows that these principles were fully54 grasped by many gunnery officers in the navy in these years. And I must confess I was extremely astonished when our proceedings at the Dardanelles in March and February and April showed that there was no common practice in the matter throughout the navy. At last, in the month of May 1915, I set out these elementary principia of indirect firing in Land and Water. “The difficulty in correcting the fire of a multitude of ships is, it may be added, twofold, because each salvo151 must be identified as coming from a particular ship, and then that ship be informed of the correction. There is apparently no escape from the necessity of having a separate spotter for each ship. If the spotter is in an independent position, the obstacles in the way of this double task are considerable. And aeroplanes are not a satisfactory substitute. At best an aeroplane can help one ship only.” It will be observed that in July the officers at the Rufigi had to work them all out again for themselves!
Nothing could better illustrate the curious individualism which governs the organization of our sea forces. Each ship, each squadron, each fleet seems to come to the study of these things as if they were virgin problems, entirely unaided by advice or information from the central authorities, so that there is not only no uniformity of practice—in itself a not unmitigated evil—but what is really serious, a total absence of uniformity of knowledge. I am the last person in the world to suggest that all naval affairs should be regulated in every petty detail from Whitehall. There are quite enough forces at work to repress freedom of thought or restrict liberty to investigate and experiment in the fullest possible way. But there is surely the widest possible difference between a restraining tyranny and an intelligent system of communicating proved principles and the results of successful practice.
