Eighty-nine Marines of 42 Commando had arrived in Brunei on 11 December, led by Captain Jeremy Moore (who later commanded the British Forces during the Falklands War). After acquiring two landing craft, the Marines were transported to Limbang by Royal Navy crews led by Captain Black (who later commanded HMS "Invincible" during the Falklands War) and staged their arrival at dawn, 13 December. The landing craft had manually operated ramps which took too long to lower and the senior officer took the decision that the Marines would vault over the sides or over the ramps under covering fire from Vickers machine guns mounted on the bridges. One landing craft's bridge was raked with Bren gun fire, disabling the crew, and the craft rammed into the river bank and quay.
