The battle for Guadalcanal that lasted from August 1942 to February 1943 was the first major American counter offensive against the Japanese in the Pacific. The battle of Savo Island on the night of 9 August 1942, saw the Japanese inflict a sever defeat on the Allied force, driving them away from Guadalcanal and leaving the just-landed marines in a perilously exposed position. This was the start of a series of night battles that culminated in the First and Second battles of Guadalcanal, fought on the nights of 13 and 15 November. One further major naval action followed, the battle of Tassafaronga on 30 November 1942, when the US Navy once again suffered a severe defeat, but this time it was too late to alter the course of the battle as the Japanese evacuated Guadalcanal in early February 1943. This title will detail the contrasting fortunes experienced by both sides over the intense course of naval battles around the island throughout the second half of 1942 that did so much to turn the tide in the Pacific.
