The Battle for Brest was fought in August and September 1944 on the Western Front during World War II. Part of the overall Battle for Brittany and the Allied plan for the invasion of mainland Europe called for the capture of port facilities, in order to ensure the timely delivery of the enormous amount of war materiel required to supply the invading Allied forces. It was estimated that the 37 Allied divisions to be on the continent by September 1944 would need 26,000 tons of supplies each day. The main port the Allied forces hoped to seize and put into their service was Brest, in northwestern France.

The Churchill Crocodile was a British flame-throwing tank of late Second World War. It was a variant of the Tank, Infantry, Mk IV (A22) Churchill Mark VII, although the Churchill Mark IV was initially chosen to be the base vehicle.
