Most of the bridge-heads were constructed by the Russians. A few, generally small ones, were made by the Germans; and some were captured by them, and the defences afterwards elaborated. In this last-named case, they proved a decided annoyance, if not danger, to the Russians: and, about this time, we had orders to destroy, or recapture, a number of them. Most of these were situated on the rivers Vistula, Warta, Pilica and Bzura. The numerous tributaries of these great streams had many fords: bridge-heads were, therefore, useless on brooks and rivulets, as they could be easily turned. The most important works of this class were on the two first-mentioned rivers; and detachments were generally sent out to make simultaneous attacks on a number of them, as this method greatly interfered with, if it did not entirely stop, the enemy sending supporting parties to any one point of the offensive line.

On the 27th of the month a number of detachments went out at night to destroy as many of the enemy's posts as possible. These parties, in our district, each consisted of a battalion at reduced strength (600 or 700 men), and about fifty sappers with hand charges of explosives. We had been moved out the previous day, and destroyed a number of temporary bridges for infantry on a stream the name of which did not transpire. We were directed, when retiring, to break the ice behind us: for the streams were all frozen over, though the larger rivers were not, having only a fringe of ice on either bank. The real objective of our expedition was three bridge-heads on the Warta protecting three bridges constructed for the passage of infantry, cavalry and artillery. These bridges were known to be not much in use at the time; but they were likely to greatly benefit the enemy later on.

Though some snow had fallen during the day the night was clear and bright, and there was more moonlight than we wanted; but the Germans were evidently off their guard. The plank-bridges on the brooks had not even been watched by a few videttes; and nothing seemed to show that they knew we had been engaged in tearing them down. There was an outpost near the first bridge-head on the Warta, beyond the village of Nishkinova, and half a section was sent to try and get between it and the bridge. The enemy must have taken this party for one of their own patrols, for they took no notice of it.

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.

There were not many men in the trench, and these were all bayoneted in less than a minute: but even in this short time the enemy in the earthwork behind the trench recovered themselves, and opened fire on us with both rifles and ordnance. Fortunately we were well spread out, and our losses were not great; the chief, and most regrettable of them being Colonel Krastnovitz, whose head was blown off. He was a very brave man, and excellent officer; and his death was a great personal loss to us all—to none more than to myself. I did not see him fall; but I soon became aware that he was down. The Major was not with us, having been previously wounded, and the command of the battalion devolved on a Captain, quite a young man, but energetic and brave, and well acquainted with his work.
