During the winter months of 1915-16 the Division took its turns in the firing-line. Every battalion experienced the hardships and dangers of the front trenches, when the weather was at its worst for chills, bronchitis, pneumonia and frost-bite, and when the Germans were most active at sniping and bombarding. Names of men in the Division began to appear in the lists of casualties within ten days of the landing in France. The battalions passed through these preliminary stages with courage, endurance and splendid determination. They quickly earned a fine reputation among the highest military commanders for such soldierly qualities as willingness and cheerfulness in doing any sort of work, however unpleasant, that fell to them in the trenches, and their coolness and alertness on such dangerous missions as going out at night to the listening posts in No Man's Land and repairing the wire entanglements. Eager to snatch their share of peril and glory, they were also among the foremost in volunteering for such wild adventures as bombing raids on the German trenches under cover of darkness. One such daring exploit by the Tyrone Volunteers was the subject of a special order of the day issued by Major-General Nugent, commanding the Division. It was as follows-- "A raid on the German trenches was carried out at midnight on ---- by the Royal Inniskilling Fusiliers. The raiding party consisted of Major W.J. Peacocke, Captain J. Weir, Lieutenant W.S. Furness, Second-lieutenant L.W.H. Stevenson, Second-Lieutenant R.W. M'Kinley, Second-Lieutenant J. Taylor, and eighty-four other ranks. The raid was completely successful, and was carried out exactly as planned. Six German dugouts, in which it is certain there were a considerable number of men, were thoroughly bombed, and a machine-gun was blown up, while a lively bombing fight took place between the blocking detachments of the raiding party and the Germans. Having accomplished the purpose of the raid, the party was withdrawn, with the loss of one man killed and two wounded. The raid was ably organised by Major Peacocke, and was carried out by the officers and men of the party exactly in accordance with the plan, and the discipline and determination of the party was all that could be desired. The Divisional Commander desires that his congratulations should be extended to all who took part in it. "Brigadier-General Hickman, in a special brigade order, says the arrangements and plans reflect the greatest credit on Colonel A. St. Q. Ricardo, D.S.O., commanding the battalion, Major Peacocke, and the other officers concerned. The whole scheme was executed with great dash and determination, cool judgment and nerve." Such was the fame of the raid and its success that the Commander-in-Chief, Sir Douglas Haig, visited the battalion and personally congratulated them.
