The destroyer escort operated on this circuit for four months while Allied forces consolidated their grip on the northern Solomons. On 5 August, while off the mouth of the Jaba River on Bougainville Island, she bombarded a small contingent of Japanese soldiers holding out against the Allied forces controlling the island. Allied aircraft reported that all of her target areas were well covered with fires. After destroying a floating mine on 19 August, "Bowers" searched the area around Bougainville and Treasury Island for a submarine reported to be in the vicinity. Her duties in the northern Solomons ended at Biak, New Guinea, where she joined a group of fleet oilers bound for the Philippines to support the American landing on Leyte.
