Another landing by motor launches and boats, carrying a detachment of Argyll and Sutherland Highlanders and a machine-gun platoon of Royal Northumberland Fusiliers, whose Vickers machine guns were to defend the perimeter, partially failed to reach the landing point. Because of extremely heavy fire from Tobruk harbour, only two launches, MTB 261 and MTB 314, made it into Marsa Umm el Sciausc, the target cove.
