Operation Fustain, the division's second mission in Sicily, was carried out by the 1st Parachute Brigade. Their objective was the Primosole Bridge across the Simeto River. The intention was for the parachute brigade, with glider-borne forces in support, to land on both sides of the river. While one battalion seized the bridge, the other two battalions would establish defensive positions to the north and south. They would then hold the bridge until relieved by the advance of XIII Corps, part of the Eighth Army which had landed on the south eastern coast three days previously.
