Colin, greetings. My grandfather William George Miller was in the same unit as William Ellis, namely 'D' Battery (4.5" howitzers) 64th Bde RFA, in fact he was wounded on 9 April 1918 during the same action W Ellis was killed in, that is the Battle Of The Lys, second phase of the German Spring Offensive of 1918, otherwise known as Operation Georgette. My grandfather was lucky though, he caught a 'Blighty One' and survived the war, which is how I come to be typing this message!
I've got a fair proportion of the war diaries of 64th Bde RFA photographed, plus some other bits and pieces which may interest you. Please feel free to contact me if you wish via
nick316@hotmail.com and maybe we can sort out some information transfer arrangements.
All the best,
Nick Miller.
