Hello Chris
I think we have much to thank Colonel Swayne for the expressive attention to detail he gave in the War Diary of 5th Labour Battalion. I have read many diaries, but his I found account quite amazing. I can't imagine what would have happened if the adjutant and colonel hadn't arrived in the first two days in Southampton. I was so pleased to read that Colonel Swayne was made Companion of the Order of St Michael and St George in the New Years Honours in 1917. He deserved it, but I don't whether it was for his efforts during that time.
As regards, my man, Thomas Richard Clarke. I found him mentioned twice in the War Diary, quite unusually. The first time, on 24th June 1916, he and another pioneer found a large stone on the level crossing and they were later questioned about it. The second time was on 5th August when it mentions he was wounded but remained on duty.
I'm afraid his hospitalisation in Le Treport was the end of his service overseas. He was sent back and was in hospital in Cedar Lawn Hospital in Hampstead, then discharged.
Happy hunting,
Judy
