The Wessex was then joined by a Lynx which launched a Mark 46 torpedo, but the weapon was configured to home on submerged submarines and passed harmlessly underneath its target. Wasps then joined the attack firing AS-12 missiles. As "Endurance" was much closer to the action, her Wasps were able to rearm and attack several times, while "Plymouth"'s Wasp was able to carry out only one attack. As the submarine approached Grytviken, Argentine positions at King Edward Point opened fire with rifles and anti-tank rockets, and during the last Wasp attack, the crew attempted to defend themselves with small arms and at least one machine gun, but with no effect. The last missile fired caused the most damage, destroying the periscope standards and nearby pumps and injuring a sailor who was manning a machine gun. By 1100, the crippled "Santa Fe" was once again moored at Grytviken pier, where she was abandoned by her crew.
