The film the wooden horse was show the other day.
It is quite amazing to think that the men who tunnelled out of a prisoner of war camp in the escape known as the "wooden horse" managed to tunnel 100 feet in three months. Only the shaft had wooden shoring meaning the rest of the tunnel carried a high risk of collapse. The three men who escaped made it back to re-join the war effort. It makes me wonder about their bravery and whether their return made any difference to the war.
