In an attempt to drive Allied forces from Guadalcanal and nearby islands and end the stalemate that had existed since September 1942, the Imperial Japanese Army planned a major ground offensive on Guadalcanal for 20–25 October 1942. In support of this offensive, and with the hope of engaging Allied naval forces, Japanese carriers and other large warships moved into a position near the southern Solomon Islands. From this location, the Japanese naval forces hoped to engage and decisively defeat any Allied (primarily U.S.) naval forces, especially carrier forces, that responded to the ground offensive. Allied naval forces also hoped to meet the Japanese naval forces in battle, with the same objectives of breaking the stalemate and decisively defeating their adversary.
