World War II At the outbreak of World War II, the U.S. Army began buildup and reorganization of its fighting forces. The division was called into active service on 3 February 1941. Elements of the division were then sent to Fort Meade, Maryland for training. The 57th and 58th Infantry Brigades were inactivated as part of an army-wide removal of brigades from divisions. Instead, the core units of the division were its three infantry regiments, along with supporting units. On 12 March 1942, over three months after the Japanese attack on Pearl Harbor and the subsequent American entrance into World War II, with this reorganization complete the division was redesignated as the 29th Infantry Division and began preparing for overseas deployment to Europe.
