The 40th Infantry Division was activated for World War II on 3 March 1941. It was at the time a
National Guard division from the California and Utah Army National Guards. It departed for
overseas service on 23 August 1942.
The Division's first overseas assignment was the defense of outer islands of Hawai'i, where
it arrived in September 1942. Training continued as defensive positions were improved and
maintained.
