The Invasion of Hawaii

With the fall of China in mid-October, the Japanese were finally willing to commit to a full scale invasion of Hawaii. By December 1943, Japan initiated its assault. With fuel stocks depleted, the USAAF was unable to challenge Japanese aircraft as it soared over the islands strafing American forces, defending the Japanese landings. Oahu was first. The US Army's emaciated soldiers failed to hold back the charging Imperial troops. Pushing inland, Japanese soldiers discovered atrocities. Tales of cannibalism were related to the Japanese by Nissei who had been rounded up in camps and systematically butchered to feed the citizens. They also spoke of being beaten by American soldiers and used as slave labor to haul around equipment when fuel had run out. For the smallest offense, many were shot point blank. Others were raped. Imperial troops were quick in capturing and executing every American soldier they could find. They would also commit violent acts of murder and rape against the white civilian inhabitants as retribution.
With Oahu in their hands, and the sad state of American forces revealed, Japanese forces expanded their operations seizing the remainder of the chain throughout the end of December. Plans were drawn up to begin rebuilding the former naval installations. The Nissei became willing supporters of the Japanese, renouncing their American citizenship following the vile treatment they had received at the hands of American forces. The rays of the Imperial standard extended further eastward.
