3 Para, supported by HMS Avenger, was tasked with interdicting the Argentine supply route to Mount Longdon and shelling their supporting positions on Wireless Ridge. The first lines of the Mount Longdon defence were taken but the Paras then encountered strong resistance.

The 105mm guns of 29 Cdo and Avengers 4.5in gun subdued the defenders but the frigate had to curtail her bombardment after firing 156 rounds. 3 Para sustained the heaviest casualties in any land attack; eighteen men were killed and thirty-nine wounded. Among the dead were Sgt Ian Mackay, who was awarded a posthumous Victoria Cross for his courage and leadership.

45 Cdo began to move forward on Two Sisters after the battle on Mount Longdon had begun, but approached in silence and were not detected until they were within 500 yards of the nearest peak. The Marines pressed their advance covered by supporting fire from Glamorgan and Avenger and Two Sisters was taken by the early morning.

HMS Glamorgan and Yarmouth withdrew, leaving Avenger on the gunline to continue support for 3 Para. About seventeen miles south-west of Port Stanley, Glamorgan detected an approaching radar contact - an Exocet fired from a truck on a road behind Port Harriet -> more.

HMS Arrow returned to the Carrier Battle Group before dawn, having spent the night bombarding the Sapper Hill, racecourse and airfield areas.
