Arthur was the son of the late Arthur Morris and Hannah Morris, 44 Bulkeley Street, Stockport. He enlisted into the army, at Stockport, joining the local Territorial 6th Battalion fairly early in 1916. He went on active with the Battalion but seems to have been quickly transferred to another "service" Battalion of the Regiment and given another number, 52504. By the end of 1916 or very early 1917, he was transferred back to the 6th Battalion and given the above six-digit number (information based on the National Archives on-line medal entitlement records.
At the beginning of November 1917, the Battalion was in reserve at Chippewa Camp but, on the 11th, moved into the front line at Polderhoek (approximately 8 kilometres south east of the town centre of Ypres). Conditions were atrocious, even by the standards of the Western Front. The Battalion History records "The conditions in the Ypres Salient during this period were probably worse than in any war m history. The shell-fire covered the land with holes, which were filled with water owing to the destruction of the drainage system. The operations were therefore carried out in a big swamp. Added to this the enemy used a large amount of mustard gas, and this caused many casualties ". There was no front line trench system to speak of and the men had to dig quickly to link up a series of isolated posts, mainly shellholes half-filled with water.
The Battalion's War Diary for 12 November notes "Hostile artillery and machine gun attack throughout the day and night, mostly from Gheluvelt direction. Germans appeared very uneasy and fired considerable Very lights. All available ranks engaged in linking up front line and strengthening positions."
Arthur was one of the men out in the open. He saw that his comrade, Ben Millward, had been shot by a German sniper and he went to help him. Unfortunately, the sniper was able to fire a second successful shot, also killing Arthur. It was, presumably, too dangerous to try to recover their bodies and neither has a known grave.
