New Georgia Campaign
The 43rd Division went overseas in October 1942 and participated in the landings at Russell and Rendova Islands. Hester commanded the 43rd Division during the attack on Munda Airport held by Japanese forces at the end of July 1943. However, he was relieved of command by Major General John R. Hodge on 29 July 1943. Official reason of his dismissal was "exhaustion of combat". Hester was subsequently sent back to the United States and granted two months leave for recovery. He was also decorated with Legion of Merit for the success in the initial stages of New Georgia Campaign.
