The British SAS had a secret observation post on Many Branch Point, a ridge above Port Howard, which was discovered on 10 June 1982 by an Argentine assault section of the 601 Commando Company. During the ensuing fire fight, Captain Gavin Hamilton was killed, and his Goan signaler, Sergeant Fonseca captured. That night witnessed inaccurate shelling on Port Howard carried out by British frigates. This led to speculation among Argentinian officers that the mission of Hamilton was to act as a forward observer for naval gunfire support. Hamilton's grave can still be seen up the hill from Port Howard. The Argentines allowed the Union Flag to be placed on his coffin before burial.
