"Born in the Essex village of Great Wakering near Southend, Mr Grimes was 17 when war broke out. He had left school at 14 to work as a clerk in E K Cole’s radio factory, later renamed EKCO. It was there he met Iris, whom he would go on to marry shortly before the Tirpitz raids. He served first with 106 Squadron then joined 617 Squadron, by then famous as the ‘Dambusters’ from the ‘bouncing bomb’ raids on dams in 1943." www.dailymail.co.uk/news/article-10873149/Last-RAF-hero-sank-Adolf-Hitlers-Tirpitz-battleship-dies-three-weeks-100th-birthday.html
