by units of the main invasion force. Waters completed disembarkation and unloading operations without further incident and, by 0855, stood down Blanche Channel in company with Dent to return to Purvis Bay, where she anchored that afternoon. Rendova had been taken primarily as a stepping-stone to the main objective—Munda—as well as its airstrip— and to provide locations for supporting heavy artillery and its observation posts. By the time troops began shuttling from Rendova to Zanana—located to the east of Munda Point—for the planned occupation, Waters had picked up more troops at Guadalcanal and had landed them on the opposite coast of New Georgia. She departed Guadalcanal on 4 July and, the following morning, sent them ashore at Rice Anchorage on the northern coast of the island. The force she landed, a mixture of Marine Corps and Army units, succeeded in isolating and reducing the Japanese garrisons at Bairoko and on Enogai Inlet while the troops in the south concentrated upon the seizure of Munda without fear of interference from the north. During the next ten days, she made two more runs to New Georgia carrying reinforcements and supplies to Rendova and returning to Guadalcanal with casualties. On the morning of 13 July, in the aftermath of the naval battles of Kula Gulf and Kolombangara, she escorted the cruisers and St. Louis into Purvis Bay. Two days later, she received orders to head for Vella Lavella—located northwest of New Georgia—to pick up survivors from Helena which had been sunk during the Battle of Kula Gulf. She embarked three war correspondents at Koli Point and cleared Guadalcanal at 1325 on 15 July. At 2258 that night, she hauled in sight of her destination and began searching for the Helena sailors. At 0159 on 16 July, she lowered her boats to enter Paraso Bay. Later, she moved to Lambu Lambu cove, where her boats picked up 40 survivors from the sunken cruiser. She completed rescue operations at 0450 and departed Vella Lavella for Guadalcanal. She disembarked the 40 survivors at Tulagi just after 1300 and anchored in Purvis Bay an hour later. For the next month, Waters transported supplies, reinforcements, and garrison troops from Guadalcanal to Rendova and New Georgia and evacuated casualties in support of the mopping up of New Georgia and the capture of the remainder of the smaller islands of the group. During these operations, she served both as a
