Eastern Solomons order of battle

IJ Combined Fleet and US Pacific Fleet Commanders

Adm. Isoroku Yamamoto (HQ at Tokyo)

Adm. Chester W. Nimitz (HQ at Pearl Harbor)

The Battle of the Eastern Solomons was fought August 23–25, 1942 in the waters east and northeast of the Solomon Islands by forces of the Imperial Japanese Navy's Combined Fleet and the US Navy's Pacific Fleet. The battle resulted from a major effort by the Japanese to reinforce their troop strength on the island of Guadalcanal. The Japanese high command had realized this reinforcement was necessary following the annihilation of the Ichiki Detachment by the 1st Marines a few days earlier.

The battle can be counted both a tactical and strategic American victory: greater ship losses were inflicted on the Japanese, and the transports were turned back from their mission of landing reinforcements.
