A great deal of the enemy's barbed-wire entanglements must be cut down by means of constant artillery fire, which for days shells their wire and trenches. When the artillery has completed its work the infantry is told to be prepared to go "over the top." Each arm of the service is assigned a share in the work in the "Big Push." The engineers have various duties to perform, such as the planning and building of roads to allow the guns to move up with the advance of the infantry. In this work they are assisted by the pioneer and labour battalions. The army service corps looks after the rations, supplies, etc., working in conjunction with the ammunition columns and other branches of the service. We have, therefore, a true cooperative spirit, each branch doing its share of duty in its own particular way. The infantry is the queen arm of the service and the most important one. All other arms of the service are aids to assist it. In this great war, good artillery support is essential. On March 15, 1917, I arrived back to my battalion from a course of instruction that I had been attending at Pernes, which is one of the many schools of instruction where officers and men are sent for special courses. I located my battalion after considerable trouble at Masnil Bouche, a small village. I reported to the commanding officer of the battalion who assigned me to No. 2 Platoon of "A" Company. It was raining as usual--it seems to rain in the northern part of France every day from the middle of October until the early part of April. My company commander brought me over to my billet, which was an old-fashioned, low roof stone house. It was occupied by an old woman and two of her daughters who kept an _estaminet_ for the benefit of the troops, and incidentally a source of income for themselves. We entered the doorway and passed along a passageway to the rear of the house leading to a room about ten feet square. Until the morning of April 8th six officers slept in this small place. It also served the purpose of officers' company mess room, and some of the junior officers of "B" Company joined our mess on account of lack of accommodations, as there were only a few available houses in Masnil Bouche. The room had one double bed, which the company commander and second in command of "A" Company occupied. The junior officers slept on the stone floor. Our kitchen was outside in what might have once been a chicken coop, adjoining the house, not many yards from the window of our room, through which our meals were served. The kitchen could not even boast of a stone floor--underfoot was nothing but MUD, MUD, MUD! I was very glad to meet my brother officers as they came in for dinner that night. It is usual in France to have individual company mess, but as previously mentioned, being cramped for accommodation, "B" Company's junior officers had joined our mess.
