The half-section found two sentinels on the bridge who were completely surprised. One fellow dropped his rifle and held up his hands: the other began to cry out, but was promptly stopped by a bayonet-thrust, and his body put in the shadow under the parapet. The first man begged his life, and was told that it would be granted him if he shut his mouth, otherwise---- He took the hint: and we listened to hear if an alarm had been given. Apparently it had not been, for we could hear men singing a rousing chorus: and the white sheet of snow between us and the outwork was unbroken by any perceptible object. To the right we could just perceive the second division of the bridge-head: the third section was further up the stream. There had been no previous reconnoitring by any member of our detachment, at any rate--and we had no knowledge of the numbers or disposition of the enemy. Judging by appearances there would be at least 400 men in each work; and there might be 4,000 in reserve, somewhere behind. I could see that we were taking a good deal on trust; and how we were to pass the wire entanglements without great loss puzzled me. We had no artillery to pave the way. It had been arranged that the firing of a rocket should be the signal for the simultaneous attack on the bridge-head, or three sections of the head: for they were connected by an entrenched line. The bridge on the left, the one we first reached, was an old stone structure; the other two were made of planks supported by boats in place of pontoons. A battalion, and a section of engineers, was detailed to attack each bridge; but the arrival of the three divisions was not well timed, and we had a long and anxious wait, being, I must admit, more fortunate than skilful. We observed that the German patrol we had evaded walked right up to the main body of our battalion, and were quietly made prisoners of. They evidently mistook our men for some of their own body. It was not until two o'clock a.m. that we saw the rocket shoot upward and heard the dull explosion of its head; and immediately we rushed towards the earthwork in front of us, the apex of which was only about 200 yards from the foot of the bridge. The surprise of the enemy must have been complete: for although we heard rapid firing to the right of us, where the other two sections were operating, we were suffered to rush right up to the wire entanglement before a shot was fired at us, and we passed the obstruction and entered the trench before a man of us dropped.
