In 1942, Colonel Allan M. Ogilvie, RCAF(Ret.), was a Flight Lieutenant in his early twenties, land a navigator in a Lancaster Bomber which was shot down over occupied France. He parachuted to safety with only minor injuries, and then had to decide whether to let himself be captured, and spend the remainder of the war in close confinement but relative safety, or attempt an escape through hostile territory to a neutral country. There was a great danger that if captured posing as a civilian, he could be executed as a spy.
He chose to attempt an escape, and, with the help of the French Underground, spent the next three months walking and hiding as he worked his way into Spain.
