According to Wiesenthal, on 20 April 1943, Second Lieutenant Gustav Wilhaus, second in command at the Janowska camp, decided to shoot 54 Jewish intellectuals in celebration of Hitler's 54th birthday. Unable to find enough such people still alive at Janowska, Wilhaus ordered a roundup of prisoners from the satellite camps. Wiesenthal and two other inmates were taken from the Eastern Railway camp to the execution site, a trench deep and long at a nearby sandpit. The men were stripped and led through "the Hose", a six- or seven-foot wide barbed wire corridor to the execution ground. The victims were shot and their bodies allowed to fall into the pit. Wiesenthal, waiting to be shot, heard someone call out his name. He was returned alive to the camp; Kohlrautz had convinced his superiors that Wiesenthal was the best man available to paint a giant poster in honour of Hitler's birthday.
