Snow Tracs, predecessors of the Bv202s, but only six were landed in the first few days. There was also 160 Provost Company, Royal Military Police and 6 Field Cash Office, Royal Army Pay Corps. These logistic units constituted an augmentation of the Commando Logistic Regiment, rather than the logistic support required by a brigade engaged in combat operations. As a result, the 5th Infantry Brigade's arrival in the Falklands meant that the Commando Logistic Regiment became responsible for supporting two large brigades with a total strength of around 9,000 personnel. This placed stress on the regiment, as it was structured to support only the 3rd Commando Brigade's 3,000 personnel, and it had deployed to the Falklands with less than its usual allocations of manpower and transport. The coastal vessel MV Monsunen was used by the Argentinians until forced aground near Goose Green by Yarmouth on 23 May. It was salvaged by a prize crew from Fearless, and used to supplement the 5th Infantry Brigade's transport. While the 3rd Commando Brigade advanced on Port Stanley on a northerly axis, the 5th Infantry Brigade advanced on a southerly one. The plan was to establish a second FBMA at Fitzroy, with a DP at Bluff Cove. It was nowhere near as good as Teal Inlet. The route from Port San Carlos went all the way around Lafonia, a distance that landing craft and mexeflotes could not cover on their own. While the LPDs were fast enough to get there and back in darkness, the LSLs could not. Moreover, unlike at Teal Inlet, the Argentinians held the high ground overlooking it. As a result, Sir Galahad and Sir Tristram were caught unloading in daylight on 8 June and attacked by Argentine aircraft, and both were set ablaze. The fires on Sir Tristram soon burned themselves out, and some of the cargo was saved; ultimately, the ship was salvaged. But Sir Galahad was a total loss. The disaster cost 49 men their lives; another 115 were wounded. Among the dead were four Chinese crewmen. The field hospital was flooded with casualties, and arrangements were made for landing craft to send two dozen each to Fearless, Intrepid and Atlantic Causeway; others were flown to Uganda. That same day, one of the LCUs from Fearless was caught in open water in daylight, and attacked and sunk by Argentine aircraft, killing six men. On board were six Land
