Major Bannatyne is not to be found in any of the Battalion photographs on the website. When were the photographs taken, and are there any others available?
According to the records I have seen, he was transferred from the 11th Hussars to the 23rd Battalion, the Manchester Regiment, in November, 1914. He signed the war diary for April, 1916, as Major, Comdg. 23rd Battalion, and he died of wounds after an artillery barrage on 14th May, 1916.
