Eric “Digger” Dowling, who forged passports, made maps and helped to dig the one tunnel that the Germans did not discover before the Great Escape from Stalag Luft III, has died, aged 92. On March 24, 1944, 250 prisoners lined up to await their turn to crawl through the tunnel to freedom. Many of them were equipped with documents that had been forged by Mr Dowling, who learnt to speak five languages fluently during his three years in the prison.
