No Overflix. Graeme Warrack was Divisional Chief Doctor of the 1st Airborne Division at the Battle of Arnhem in September 1944. With other doctors, medical personnel and padres, he stayed behind with the wounded. The first improvised hospital was a German-occupied Dutch military barracks at Apeldoorn. From here, the wounded were transported to prisoner of war camps in Germany. As the last of the wounded left, Colonel Warrack escaped.
