Captain Peter Babbington's K Company crossed their start line first and proceeded up the mountain undetected, knifing two sentries on the way. They remained undetected until they approached Sub-Lieutenant Mario Juarez' 120 mm mortar platoon positions and decided to engage them. They were assisted in the advance by HMS "Yarmouth"'s, artillery, and their own battalions mortars. During the engagement, Second Lieutenant Juarez was badly wounded firing his handgun in the dark and Corporal Laurence G Watts from K Company was killed clearing the occupants of a tent. The supporting British artillery batteries and mortar crews fired over 1,000 rounds to keep the Argentines pinned down, and helped stop the defenders getting a proper aim at the Royal Marines from K and L Companies.
