 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 .
