My dad was in the RASC, and was at St Nazaire on 17th June 1940.
I wish he was still alive for me to ask him more details of what happened.
He told me that he got to Falmouth and troops were asking to use the phone in the Post Office to phone to their families to let them know they were back in England. Apparently my dad got through to home and told them he was back in England, and said "Tell Joyce that we will get married as soon as possible" At which a big cheer went up from the big crowd in the Post Office. He got married on the 23rd June.
