One of the objectives of the Dieppe Raid was to discover the importance and performance of a German radar station on the cliff-top to the east of the town of Pourville. To achieve this, RAF Flight Sergeant Jack Nissenthall, a radar specialist, was attached to the South Saskatchewan Regiment landing at Green Beach. He was to attempt to enter the radar station and learn its secrets, accompanied by a small unit of 11 men of the Saskatchewans as bodyguards. Nissenthall volunteered for the mission fully aware that, due to the highly sensitive nature of his knowledge of Allied radar technology, his Saskatchewan bodyguard unit was under orders to kill him to prevent him from being captured. He also carried a cyanide pill as a last resort.
