John Pendlebury, the archaeologist, at Heraklion on 22 May 1941

John Pendlebury was a British archaeologist who was working on reconstructing the bronze age on the island of Crete. During the war, he was apparently working for British intelligence. He had been in Britain for training from the outbreak of the war until May 1940, when he returned to Heraklion. He was near Heraklion during the initial attack on 20 May 1941. He spoke Greek like a native and was assimilated into Cretan society. With his Cretan companions, he was going to participate in an attack on German troops. Along the way, he fired on some Germans. There were Ju-87 divebombers overhead and John Pendlebury was shot in the chest. He was taken to a house. He was eventually treated by a German doctor, but some passing German paratroops took him outside and executed him. His body was eventually transported to the cemetary near Suda Bay.
