Photograph showing W.E. Hammond and D. Lister in Switzerland after escaping from their prisoner of war camp at Lamsdorf. Armed with forged identity papers, money and civilian clothing, Hammond and Lister volunteered to wash up the Sunday soup cauldrons in the wash house and slipped out of the camp through a nearby garden. They travelled by train to join the Colditz escape route at Dresden, showing German cigarettes as they passed through the police checks. Going via Nuremburg [sic] they continued to Ulm, accepting a drink from a German soldier along the way. Finally they ended up in Switzerland where they later held a great Christmas party with other escapers.
