Just summarised this from the War Diary of 1st Bn GG:
"4th Nov (7th Brigade) marched to LOCRE - Billeted there - South-west of Ypres
7th Nov - Organised into one company due to shortage of officers
8th Nov - Being re-equipped - Church parade @10.30am
11th Nov - Four officers, along with 401 men joined the Battalion
12th Nov - Two officers, along with another 133 men joined the Battalion. Afternoon spent in re-organising the Battalion and posting the Draft to companies.
13th Nov - Had an hours parade in the morning - afternoon spent in re-equipping the Battalion.
14th Nov - Parade 7.30am - Passed through BAILLEUL, STEENWERKE, had dinners at BAC-ST-MUR. Left Gordons in Reserve - Started at 5pm to relieve Leicesters in the 19th Brigade in the trenches. - Lt. Ward wounded in the arm - Lt. Lord Claud Hamilton taken to hospital with a sprained ankle......................."
Apart from one officer wounded and another taken to hospital with a sprained ankle there were no casualties reported either on the 11th Nov / 12 November (whichever day applies to the death of George Bateman). It seems very conclusive in supporting the earlier evidence that George Bateman was in the 2nd GG and not the 1st GG.
Regarding the proximity of the Railway Chateau Cemetery where George's body lies, to the action by the 2nd GG, the Cemetery appears to be about 2 Km to the west of Ypres.
I am so grateful for all your help with this query. Interestingly, George had a cousin who 'fell' 3 years later, in 1917. He was a member of a different Regiment, again fighting around Ypres. Pursuing him will be a query for another day. You may, therefore, hear from me again.
Very best wishes,
