Henry was born in Heaton Norris and, at the time of the 1901 Census, he was living in Stockport, aged 16, and working as a warehouseman. His only known family was an older brother, Joe, then aged 30 and working as a "cotton thread doubler".
Henry's service number indicates he enlisted into the army in September 1914, probably going overseas with the rest of the Battalion on 25 September 1915.
On 22 July 1916, the Battalion went into trenches opposite Beaumont-Hamel in the heart of the Somme battlefield. The following is the official account of the tour of duty, contained in the Batatlion's War Diary:-
"This line was very quiet.....A trench "Hunter Trench" is being dug about 200 yards in front of our present front line and is daily damaged by shells and trench mortars of the Bosch who takes a particular delight in scattering shells all over No Man's Land during the night. The trenches we took over though badly knocked about in places were a great improvement on the Thiepval ditches or the Bosch lines at Ovillers and should assist the Battalion in finding its feet again. On the night of 29/30 the working party in the Sunken Road or Hunters trench was badly cut up by trench mortars and shells."
A year later, the Stockport Express published an "In Memorium" notice in its edition of 2 August 1917. Joe Thompson had arranged for its insertion. Joe was then living at 7 Lorne Street, Peel, Green, Patricroft, Salford.
