During this time Lieutenant Walker, Lieutenant Harcourt Vernon, and Lieutenant MacKenzie were all badly wounded.
But while a satisfactory foothold had been obtained here, Sir Douglas Haig found that there was a gap between the First and Second Corps. Being very hard pressed, with no reserves available, he sent back for help to the Commander-in-Chief, who at once placed the Cavalry Division at his disposal. On foot, the cavalry was despatched to the left to prolong the line occupied by the 4th Brigade, and succeeded in repelling the German attacks.
A steady fire was being kept up by the 4th Brigade at the German front line, which was lying down close in front of it in a mangel and beet field, and therefore very hard to see. The German fire suddenly began to slacken, and the moment seemed to have arrived for a charge, when, without any warning, the men in the German leading line ran forward with their hands over their heads in token of surrender, and at the same time white flags appeared in various parts of the line. At once a large number of our men leaped up and ran to meet them. Major Jeffreys and Major Matheson, fully alive to the possibilities of danger, shouted and yelled to them to stop, but the men ran on, eager to capture so many prisoners, and soon British and Germans were mingled together in a confused mass.
At this point the German supports opened fire on them all, mowing down friend and foe alike, and killing a large number of both sides. Most of those who were unhit dropped down at once where they were in the root field, and when it got dark many of the Germans walked into our lines and surrendered. It must be added that there is no evidence that this treachery was deliberately planned. It would seem that the leading line had had enough, and genuinely meant to surrender; the supports had no such intention, and there is thus perhaps some justification for their action. But it was a lesson to the 4th Brigade which it never forgot. Thenceforth the white flag was looked on with suspicion, and whenever it was used, not a man moved from his place.
After a hurried consultation between Major Matheson, Major Jeffreys, and Major Lord Bernard Lennox, it was agreed that, while Major Jeffreys held the enemy in check in front, the other two should take some men with them, and try to work round the German flank. This operation took some time, but evidently it surprised the Germans, who were holding a ridge about 500 yards in front of our firing line. Many of them could be seen running from right to left across the front, and offered a fine target for our men posted at the edge of the wood—the shooting was good and hardly a man escaped. Lieutenant Stewart was ordered to advance with a platoon of No. 4 Company, and managed to get on another 300 yards when he was wounded.
The difficulties of the situation were now borne in on Major Jeffreys and Major Matheson. It was getting dark, and they could get no orders from Brigade Headquarters, as the telephone wires had all been cut by bursting shells. Signalling was out of the question owing to the density of the woods. Meanwhile, the Germans were still shelling the road, and it seemed only too probable that the orderly who had been bringing instructions from the Brigade had been killed on his way. The men were dead-tired, having had nothing to eat all day, and Major Matheson, who had found it a very hard matter to get through the wood to the right, came to the conclusion that no advance could be made in this direction without reinforcements.
Therefore it was decided that the only thing to do was to re-sort the battalions and to dig in where they were. A point of junction was arranged, and the much mixed battalions were reorganised; digging started, and the men, tired out as they were, set to work with a will, and soon produced a trench. Thus was the beginning made of that long line of trenches which was eventually to stretch from the Argonne to the Belgian coast, and which formed the battleground of the two armies for years to come.
Converted into a dressing-station, the farm of La Cour de Soupir was filled with wounded, British and German. The ground in front of our trench was covered with dead and wounded Germans, but though as many stretcher-bearers as possible were sent out and worked all night long, it was not easy to find them in the darkness. It was a striking point of difference that while our wounded hardly made a sound, the Germans never stopped groaning and crying out: there was a continuous chorus all through the night of "Kamerad, Kamerad," and "Wasser, Wasser." A regular pile of Germans was discovered round two haystacks, while in a stubble-field close by was an almost complete firing line, laid out in a row, and all dead. Shelling began again at dawn before all the German wounded could be brought in.
Soon the farm was crowded, and the men for whom there was no room were put in the out-buildings. The removal of the wounded from the farm to the rear proved a great difficulty. The pontoon bridge at Pont-Arcy had been smashed, and on that side of the river, unfortunately, there were only four horse ambulance-wagons; these, with their fagged-out horses, had to plod throughout the night up and down the steep hill which led to the farm, taking only a few wounded at a time.
Behind the farm was a deep quarry with several caves in it; here the men not actually required for the firing line were stationed—comparatively safe except for an occasional shell from a German howitzer. The three or four hundred prisoners the Battalion had taken were herded together in the quarry under a guard and sent downhill next day. They made no attempt to hide their pleasure at escaping from the battle.
