After the very strenuous days at the end of March, when the German attacks were successfully repelled, the 1st Battalion remained in the front line for two days, but whether the enemy considered it wiser to try some other parts of the line, or whether they were merely waiting for reinforcements, they showed very little signs of life. A heavy bombardment, directed against the Canadians on the left, which was vigorously responded to, seemed to indicate an attack in that direction, but by the time the 1st Battalion was relieved no move on the part of the enemy had taken place. After two days' rest at Blaireville the 1st Battalion returned to the trenches at Boisleux-au-Mont, where the line was singularly quiet. Early on the 5th a desultory bombardment commenced on our front line, but only with shells of light calibre. Later the railway station came under fire from the heavy guns, but by 9 A.M. all was quiet again, and no more shells were sent over by the enemy that day. Although infinite trouble had been taken to conceal Battalion Headquarters, a big flight of hostile aeroplanes flying low was able to locate it, and the enemy made some very accurate shooting. On the 8th the enemy began a gas bombardment, and obtained several direct hits on the entrance to the Battalion Headquarters dug-out and on two Lewis-gun posts. A new gas containing ether, which gave off little or no smell, was used by the enemy, and accounted for a large number of the Battalion Staff. After two more days' rest at Blaireville, the 1st Battalion returned to the trenches, where, although the shelling was light, the enemy's aircraft was very active, often flying low and firing into the trenches. Patrols were sent out along the whole frontage on the night of the 11th, and one under Second Lieutenant R. Holmes and Sergeant Brown failed to return. Little, however, was seen of the enemy, although a wiring party was encountered once, and another time the Germans could be heard demolishing a hut near the main Arras--Bapaume road. The next day the enemy occasionally fired with the Minenwerfer, but there was no shelling to speak of. In the evening Lieutenant R. Holmes and his patrol returned, having been cut off on the previous night by very strong parties of the enemy. Finding they were unable to regain our lines, they hid in shell-holes throughout the day, and took advantage of the darkness when night came to get back. On the 14th, when the usual patrols went out, Second Lieutenant W. Fleet took out a strong party to visit a German machine-gun post, which had come under the observation of a patrol on the previous night. Approaching it with caution, he found that it was unoccupied, but a German rifle, which he brought back, seemed to show that the enemy had been there lately. Four escaped British prisoners, who had been captured on the 21st, re-entered our lines near the sunken road; they belonged to the Sixth Division. The 1st Battalion went for ten days'
