The night of 24 September she helped guard an amphibious landing convoy to Vella Lavella Island, then departed to escort high-speed transports to Rendova Island. She soon turned back to Vella Lavella Island at full speed, having received word that unloading tank landing craft there were under enemy air attack. The attack had ceased by the time she reached the scene, but she launched motor whaleboats with medical and rescue parties to aid the wounded.
