Overview: The Japanese Navy is ascendant in its conquests, of which its linchpin is the main base at Rabaul in the New Britain Islands. This Victory at Sea episode refers to the US strategy of surrounding and strangling the Japanese base in the fall of 1943 through set piece invasions of its surrounding islands (Bouganville, Rendova). Praise should be given to the Seabees, which made the airfields operational in a short time, and observation planes and radar, which helped the U.S. Navy stop cold Japanese reinforcements and counterattacks.
