I've just started to look into the history of my Grandfather's service, and am confused by some Army terms, and some apparently conflicting information. Can anyone help, please? The service record says he joined up in May 1916 and was posted to 99Bn Training Reserve. That's easy to understand. But then: 20th May 1917 Posted to ROYAL WEST KENT Regt and Embarked for BEF. According to their Regimental History site, the Royal West Kents spend much of the war in India, Pakistan and the Dardanelles. Can anyone help with that mystery? And then 5th June 1917 posted to 2 Bn Royal Fusiliers Their history website doesn't have details before August 1917, so can anyone help with that? Then, he was in sick bay and there are some abbreviations I don't understand so can anyone advise what's meant by - Deck to Fd Amb: Field? Apparently this happened at Dullens Road Etaples which is now a big cemetery but may have had a field hospital. Then he 'joined Ex2 Con Dept' still at Etaples. What does this mean? Then he was classed P.B. due to injuries. What does that mean? Then he seems to have been a naughty boy as he had '3 days CC not complying with an order'. Would CC be 'confined to something'? Finally he moved to the Labour Corps (possibly as he wasn't fit to return?) joining 715 Coy and moving to 49 Coy in October 1919. I can't find any record of where they were at those times. Again, can anyone help? Sorry if it's such a long post, but I'm hoping different people might help with different areas of his career in France. He was born in 1899 so would have been 17 years 3 months old when he joined, and one month short of his 21st birthday when he left.
