Operation Fustian was a British airborne forces mission during the Allied invasion of Sicily in the Second World War. The operation was carried out by the 1st Parachute Brigade, part of the 1st Airborne Division. Their objective was the Primosole Bridge across the Simeto River. The intention was for the brigade, with glider-borne forces in support, to land on both sides of the river. They would then capture the bridge and secure the surrounding area until relieved by the advance of XIII Corps, which had landed on the south eastern coast three days previously. Because the bridge was the only crossing on the river, and would give the Eighth Army access to the Catania plain, its capture was expected to speed the advance and lead to the eventual defeat of the Axis forces in Sicily.
