Imperial Sunset is a moderate level complexity simulation of the largest naval battle in history, the Battle of Leyte Gulf. The battle was fought from October 23-26 1944 as the US returned to the Philippines, landing on the island of Leyte. The US Navy and the Imperial Japanese Navy fought a series of actions that collectively have been recorded as the Battle of Leyte Gulf. The historical result was a decisive defeat of the Imperial Navy, virtually eliminating it as a viable force for the remainder of the war. For the US Navy, it was a victory that was almost squandered due to command problems.
