Prisoner of War Map
Murky posts the story of the map his grandfather kept while a prisoner of war during World War II, along with scans of the map itself.
It is a flimsy document, held together with a wing and a prayer, and a few pieces of tape. The map was kept in the camp, and the prisoners used it to follow troop movements which they heard from local Germans at their work placements, one of which was working in a plant which helped to make V2 rockets — an activity they were forced to do.
…The map was hidden by being wrapped in oil skins, and it was kept in the pot of constantly boiling water which they used in the hut for various purposes.
