The farm is at the northernmost end of where they were.
He could have been anywhere along the yellow line.
I've been doing a lot of homework Jim and Andy, thanks to your great leads. I've read the 1916 War Diary of 2/8th Warwickshire and the 1917 diary associated with the Honourable Artillery Corps. There's been much map reading and artillery reading, and of trench warfare and creeping barrages (especially first person accounts in contrast with Press Association news) and you-name-it.
I found that Thomas Richard Beach, Regt. No. 3730, 2/8th Warwickshire, died on his first ever Trench Raid close to midnight on the 26th June 1916. It was only his and his comrades' 3rd night in a trench. He was part of 'D' Coy, under the command of Second Lt. Charles Victor While and they had been ordered to move to Hun Street Trench on the southern outskirts of Neuve Chapelle to perform their raid.
(From what I've read, this type of tactic sounds frightening and extremely dangerous)
In the interests of anyone looking for the deaths of my Prvt. Thomas Richard Beach, Second Lt. Charles Victor While and Lt. Edward Cedric Hooton; and the missing Capt. G.C.Field (who ended up a prisoner), this is what happened:
"Raid on enemy trenches S. 5. b. 51. Raining 5pm.-11pm.
11.40.pm. Artillery bombardment enemy's front line trenches 12 am. Artillery lifted to enemy's support trenches.
1.0 am. Artillery lowered to enemy's frontline trenches. 1.15 am. artillery cease fire 11.40pm.
11.40.pm. 'D' Company advanced on enemy's trenches Returned 12.50am.
Casualties. Killed. Offrs 1 (2Lt. WHILE). O.R. 2: Wounded Offrs. nil. O.R. 20 (includes 1 m-duty) Missing Offrs 2 (Capt FIELD, LT. HOOTON). O.R. 15"I notice they didn't capture anyone (it eventuated some of the missing got captured), there was no report of a 'successful' mission, no taking of prisoners. Sure, often the goal of this tactic was to intimidate the enemy or gain new information (via capturing and identifying the enemy etc) - what an expensive waste of life!
Here's the map of where this raid took place. It's about 4 kms south of Bird Cage trenches, Jim. As you said, Thomas could have been anywhere along that line. I've roughly coloured the enemy trench area.
