Two companies were placed in the front line with one company in support and one in reserve, and officers' patrols were sent out every night from dusk to dawn, but there was no movement on the part of the enemy. On the 10th the Battalion moved back into support, and on the 15th into Divisional Reserve, where it remained for three days. From the 19th to the 24th the Battalion went up again into the front trenches, where the work consisted of improving the line by laying down duckboards and digging sumps and latrines. Fifteen officers, 30 sergeants, and 55 corporals from the American Army were attached to the Battalion, and were distributed between the four companies and Battalion Headquarters. Lieutenant S. G. Fairbairn, Second Lieutenant H. P. Gordon, and Second Lieutenant S. Calvocoressi arrived during this tour of duty in the trenches, and on the 25th the Battalion retired into support, where more officers and men of the American Army were attached for instruction. On the 30th the Battalion moved back into Divisional Reserve. [Sidenote: Aug.] After four days in reserve the Battalion went up into the front line near Adinfer, where it remained for a week carrying out inter-company relief. In this part of the line patrols were sent out every night, and a company from the 320th Regiment of the United States Army, which accompanied the Battalion, supplied a certain number of men for this purpose. On the 6th Second Lieutenant R. P. Papillon when out on patrol duty, encountered a German patrol in Observation Trench, and after severely wounding one of the enemy, succeeded in bringing back an identification mark. The Higher Command, however, required further information, and accordingly a special patrol was sent out on the night of the 10th. Captain Churchill, whose great experience in all kinds of incursions into the enemy's line rendered him eminently fitted for the task, was sent from the Brigade Headquarters, to take charge of the party, which consisted of Second Lieutenant de Reuter and seven men. A covering-party composed of thirteen men, under the command of Sergeant Birtles, accompanied the raiders. Hardly had the patrol started, when a shell fell among them, wounding one man, who had to be carried back to the trenches. Following the German outpost line, which consisted of small adjacent rifle-pits, but which showed no sign of frequent occupation, the patrol came on the German wire. This formidable obstacle consisted of barbed wire in concertina shape, staked to the ground, with strands running through it. After a careful search a gap was found, and through this the patrol went. After following the track for about forty yards a German sentry was seen. The patrol stood still, and the sentry walked away unconscious of its presence. Soon afterwards some more of the enemy were seen moving round to the left of the track. They were evidently suspicious, as they only whispered. Three of them came crawling slowly towards the patrol.
