This book will cover the fierce night naval battles fought after Guadalcanal between the US Navy and the Imperial Japanese Navy during late 1943 as the Allies advanced slowly up the Solomons Islands toward the major Japanese naval base at Rabaul. During this period, several vicious actions were fought around the American beachheads on the islands of New Georgia, Kolombangara and Vella Lavella in the central Solomons. These battles featured the most modern destroyers of both navies. Throughout most of 1942, the Imperial Navy had held a marked edge in night-fighting during the six-month long struggle for Guadalcanal. A key ingredient of these Japanese successes was their destroyer force which combined superior training and tactics with the most capable torpedo in the world, known to the Allies as the "Long Lance". Even into 1943, at the battles of Kula Gulf and Kolombangara, mixed Allied light cruiser/destroyer forces were roughly handled by Japanese destroyers. After these battles, the Americans decided to stop chasing Japanese destroyers with cruisers so the remainder of the battles in 1943 (with one exception) were classic destroyer duels. The Americans still enjoyed the technical edge provided to them by radar, and now added new, more aggressive tactics. After four more destroyer duels during the second half of 1943, the final result was the defeat of the Imperial Navy's finely trained destroyer force and the demonstration that the Japanese were unable to stop the Allies' advance.
