Lance Corporal Honer and Private Brennan

Lance Corporal George T. Honer and Private Brennan, photographed in Bethune in 1915. George Honer, Service Nos 1374 (NIH) and 71360 (Corps of Hussars), arrived in France on 17 November 1915 as part of F Squadron (later renamed B Squadron). At some stage he qualified for a Silver War Badge as a result of sickness or wounds, and was discharged on 3 January 1919.
The precise identity 'Brennan' is not clear, as unfortunately there were three men of that name in F Squadron. They were:
Private William Brennan (Service No. 1643), who was later promoted to Corporal. He transferred into the 9th Battalion Royal Irish Fusiliers when the Regiment was dismounted in August 1917.
Private Herbert Brennan (Service Nos 1357 (NIH) and 71349 (Corps of Hussars), who died in France while serving with the V Corps Cyclist Battalion (North Irish Horse) on 3 November 1918
Sergeant Alexander Brennan, Service No. 1226, who later joined the 2nd Royal Canadian Regiment as a 2nd Lieutenant. (However there is no sign of sergeant's striped on the sleeves of the man in the photo.)
The writing on the picture states that these men belonged to 1 Troop of 'B' Squadron North Irish Horse, 32nd Divisional Cavalry, and was taken at Bethune in 1915. This is somewhat of a mystery, as the Squadron was with 33rd, not 32nd Divisional Cavalry in 1915. It did join the 32nd in May 1916, but by then had left the Bethune area.
