Hi there. Just found this link and was eager to reply. I'm the grandson of the other Gunner Graham who served with 154 Siege Battery and I would appreciate some help or some pointers. My Granddad (William Graham, 55851) was awarded the DCM at Voormezele in August 1917 and is also mentioned in Capt Walkers book. I have all available War Diary accounts of 154 SB activities from April 1917 to January 1918, however, my granddad was transferred to 188 SB as Battery Quartermaster Sergeant in April 1918 and there the leads run dry. I have a couple of questions... Does anyone know if anybody else was transferred at that time? In the absence of any War Diaries, where is the next best source of information? I went to Ypes in May last year and visited some sites where 154 SB were positioned. I'd be more than happy to share any info I have with anyone else researching "The Sailly Boys". Best regards
