Guadalcanal campaign
The convoy also delivered 137 vehicles, tents, aviation fuel, ammunition, rations and engineering equipment to Guadalcanal. These new soldiers enabled Vandegrift, beginning on 19 September, to establish an unbroken defence around the Lunga perimeter. While protecting this convoy the aircraft carrier  was sunk by the Japanese submarine  southeast of Guadalcanal. For a while, this left only one Allied aircraft carrier () in the South Pacific area.
