How a single, panicked order doomed the most disastrous convoy of World War II

The biggest convoy disaster of WW2 | Convoy PQ-17 · 13:28 · Video: Imperial War Museums · Watch at the source

In short: Convoy PQ-17 departed Iceland in 1942 with 34 merchant ships, but only 11 reached their destination. This video examines the catastrophic decision to scatter the fleet, which left defenseless vessels vulnerable to German forces and resulted in the greatest loss of any single British convoy during the war.

On June 27, 1942, convoy PQ-17 began its journey to the Soviet Union. While the convoy initially repelled German air attacks, the situation shifted on July 4 when Admiral Sir Dudley Pound issued a command for the convoy to scatter. Fearing an imminent strike by the German battleship Tirpitz, the escort ships retreated west, leaving the merchant vessels to navigate alone.

The order was based on a critical intelligence failure: the Tirpitz was actually still moored in northern Norway. Without protection, two-thirds of the convoy were destroyed by U-boats and aircraft over the next week. The video, featuring Rob Rumble from HMS Belfast, investigates the motivations behind Admiral Pound’s decision, the experiences of the sailors involved, and the broader impact of this tragedy on the war effort.
