American troops in WW2 in London
Group
During WW2 the US armed forces worshipped at the Grosvenor Chapel and partied at Rainbow Corner.
This seems a good place to mention the searchable on-line honour roll of 28,000 Americans based in Britain who were killed in action in WW2. The actual book was presented by Eisenhower in 1951 and is held in St Paul's American Memorial Chapel, bombed in the war but rebuilt.
