Wilfred was the son of Mr F Midwinter, 36 Sweetman Street, Wolverhampton, but lived with his aunt, Eleanor, at 13 Wilmslow Road, Cheadle. Like many local men, he worked at Clay's Bleachworks. In 1918, a Sarah Ann Midwinter was registered as a voter at 95 High Street, Cheadle and, presumably, was another relative. Wilfred seems to have some connection, other than being a customer, with the White Hart pub in the village. It's uncertain if this was a family connection or if he might have worked there at some time.
He was almost certainly a pre-war member of the Territorials and was mobilised when war was declared. The Battalion's first months of war service are described here.
On 13 July 1916, the Battalion was making its way forward from billets at Gorre, prior to going into the front line to relieve another battalion, in the area of Givenchy. The scheduling of reliefs, on both sides, tended to be known to the enemy and it was a favourite time for artillery shelling of the positions. It seems that there was no exception this day and five members of the Battalion were killed.
