Unbeaten left the island again on the evening of the 24th of June 1941, destined for her third patrol, only two days after returning from her last jaunt. She would head north to join the submarines Urge and Upholder which were already on station. The position of Unbeaten’s patrol area was a long way off Cape Passero. She was placed there in anticipation of intelligence received stating that an enemy convoy, consisting of four large merchantmen and five destroyers, was due to pass that area. Unbeaten only remained in that area for a short period of time. The enemy convoy was actually attacked by the Fleet Air Arm some distance from Unbeaten. Not long afterwards the boat received a recall back to Malta, safely entering harbour on Friday the 27th of June 1941.
