The Man So Dangerous His Own Bodyguards Had Orders to Kill Him

On August 19, 1942, a British radar specialist landed on the German-occupied coast of France carrying a cyanide pill and a terrifying secret. His name was Jack Nissenthall, and the eleven Canadian soldiers assigned to protect him had been given an extraordinary order: if German forces were about to capture him, they were to kill him rather than allow Britain's most sensitive radar secrets to fall into enemy hands. His mission was part of the disastrous Dieppe Raid, one of the bloodiest Allied operations of World War II. While thousands of Canadian troops stormed the beaches under devastating German fire, Nissenthall had a different objective: infiltrate a heavily defended German Freya radar station overlooking the French coast, examine its advanced equipment, and bring back valuable intelligence. But almost immediately, everything began falling apart. Landing in the wrong location, Nissenthall and his escorts were forced to fight through a French village, cross a bridge under enemy fire, and climb a hillside protected by machine guns, artillery, and barbed wire. As Canadian casualties mounted, the radar station remained frustratingly out of reach. Unable to capture the installation, Nissenthall attempted a desperate alternative: crawl through enemy fire and cut the station's communication cables, forcing German operators to transmit valuable information over the radio. With German troops closing in and the Allied invasion collapsing, Nissenthall faced an even more terrifying challenge: escaping a battlefield where surrender was not an option. By the time he reached the sea, only one of his eleven Canadian bodyguards remained beside him. Even then, German aircraft attacked their escape craft, threatening to send the survivors to the bottom of the Channel. This is the extraordinary story of Jack Nissenthall's secret mission at Dieppe, a World War II operation so dangerous that the men assigned to protect him were also ordered to become his executioners. - As images and footage of actual events are not always available, Dark Docs sometimes utilizes similar historical images and footage for dramatic effect.
