In 1989 I was commissioned to write and present a programme about the Phoney War for BBC Radio 4. My research took me to the Imperial War Museum’s sound archives and the testimony of a Dunkirk veteran called Anthony Rhodes, who was commissioned into the Royal Engineers shortly before Britain declared war on Nazi Germany in September 1939. At that stage I’d no idea Rhodes had written a book about his experiences, but what he had to say on tape was exemplary . . .
