151^st Infantry Regiment

The 151st Infantry Regiment was an Indiana National Guard regiment federalized at Indianapolis on January 17, 1941 and assigned to the 38th Infantry Division. It trained in Mississippi, Florida, and Louisiana, then sailed to Hawaii and New Guinea in 1944. The regiment landed on Leyte on December 14, 1944 and performed security duty in the Culasian Point-Barugo area under the 24th Infantry Division while the 38th Division assembled for its main Philippine operations.

On Luzon, the 151st became central to the campaign for Subic Bay, Bataan, and the Manila Bay islands. A battalion captured Grande Island without opposition on January 30, 1945, helping secure Subic Bay while other XI Corps elements took Olongapo. The regiment then entered the battle for Zig Zag Pass after release from corps reserve. Fighting west of Dinalupihan, it attacked through dense jungle and broken ridges alongside the 152nd while the 149th worked in from the east. Once the pass was reduced, the reinforced 151st conducted the amphibious assault on Mariveles at the southern tip of Bataan on February 15. That night its perimeter repelled a Japanese counterattack, and patrols soon linked with East Force moving down the peninsula.

The regiment's most distinctive service came in the clearing of Manila Bay. A battalion relieved paratroopers on Corregidor, and 2nd Battalion assaulted Caballo Island on March 27. Japanese troops in tunnel and mortar-pit defenses resisted direct assault, so engineers and infantry used fuel, demolitions, and close security to finish the position. On April 13, Company F supported the seizure of El Fraile, the concrete fortress known as Fort Drum, where oil and demolitions destroyed the Japanese garrison. On April 16, 1st Battalion landed on Carabao Island and found it abandoned. The 151st later guarded flanks and routes during the 38th Division's Wawa Dam operation and ended the war in the Manila area.
