Hobart's Funnies: Engineering Innovation That Won D-Day

The General Who Was Too Clever

Percy Hobart was one of the most brilliant and difficult officers in the British Army. A pioneer of armoured warfare in the 1930s, he was forced into retirement in 1940 and reduced to serving as a corporal in the Home Guard. It took Winston Churchill's personal intervention to recall him to active service.

The Problem

The Dieppe Raid of 1942 demonstrated that conventional tanks could not operate effectively on defended beaches. They bogged down in shingle, were stopped by sea walls, and were vulnerable to anti-tank guns. A new approach was needed for any future amphibious invasion.

The Solution

Hobart assembled the 79th Armoured Division and developed a range of specially modified tanks: Sherman Crabs with chain flails to clear minefields; Churchill AVREs carrying demolition charges; DD (Duplex Drive) swimming tanks; Crocodile flame-throwers; and bridge-laying Churchills. Each addressed a specific obstacle that had defeated conventional armour at Dieppe.

D-Day Results

On 6 June 1944, Hobart's Funnies were used extensively on Sword, Juno, and Gold beaches. The British and Canadian forces, equipped with these specialised tanks, suffered significantly fewer casualties than the Americans on Omaha Beach, who had declined Hobart's offer of his vehicles.
