298th & 299th Infantry Regiments

The troop ship USAT Royal T. Frank was torpedoed while transporting trainees from Oahu to Hilo; 17 die in the attack. The surviving soldiers ultimately became part of the Hawaiian Provisional Battalion, from which the 100th Infantry Battalion (Separate) was formed.

298th & 299th Infantry Regiments of the Hawaii Territorial Guard are federalized. Over the coming year, their ranks swell with 3,000 Hawaii draftees, half of them Nisei.
