I have a puzzle. The writer of some letters in my possession served with REME in WW2 and at this point, December 1943/January 1944, he was still stationed in England. He was on leave for ten days, spanning the Christmas period. In his letter to his sweetheart, written from his home, he said that he would have to return to his Unit in Eastbourne at the end of his leave. His first letter after his return from leave informs us however that he returned to Upstreet, near Canterbury - a completely different place. My puzzle/question is:- assuming that he had been told to report to Eastbourne when he left his unit to go on leave, how would he have received the instructions to report to a different location? The same question applies to any other soldier on leave at that time - what means of communication would there have been in these situations? I imagine that perhaps telegrams were used, or maybe they had some arrangements at railway stations? If anyone can point me in the direction of a source of information about this (printed material at the time perhaps? or an authenticated account?) I would be very grateful. I'm also interested in hearing from a serving or ex-military member of the forum who can explain how they were informed of changes whilst they were on leave (ie post-WW2 and in the modern, technologically advanced era)
