The mission had been planned at short notice, following an offer by the Italian government to open the ports of Taranto and Brindisi on the heel of Italy to the Allies. The 1st Airborne Division was selected to undertake the mission, but at the time they were located in North Africa. A shortage of transport aircraft meant the division could not land by parachute and glider, and all the landing craft in the area were already allocated to the other landings: Operation Avalanche at Salerno on the western coast, and Operation Baytown at Calabria. Instead, the division had to be transported across the Mediterranean by ships of the Royal Navy. The landing was unopposed, and the airborne division successfully captured the ports of Taranto, and later Brindisi on the Adriatic coast, in working order.
