A strong Japanese naval force was dispatched in response from Rabaul in an effort to disrupt the landing operations and, overnight on 1/2 November, clashed with a force of US cruisers and destroyers during the Battle of Empress Augusta Bay. Heavy losses resulted for the Japanese and the force eventually returned to Rabaul. Meanwhile, on the second day, the remaining stores and equipment were unloaded from the transports. Over the course of the two days following the landing, the US troops ashore consolidated their beachhead and began patrolling operations as they worked to secure the perimeter. This was firmly established by 3 November, when Torokina Island was occupied.
