The 65th Infantry originated as a Puerto Rican outfit in the form of the Battalion of Porto Rican Volunteers (May 20, 1899) in the aftermath of the Spanish-American War of 1898. They were regarded as colonial troops, part of the first “American Colonial Army.” In 1908, and by then a regiment, the unit officially became part of the U.S. Army. It came to be known as the Porto Rican Regiment. During WWI the regiment was sent to the Canal Zone in Panama- far from the European battlefields. In 1920, the unit’s name changed from the Porto Rican Regiment to the 65th Infantry Regiment, United States Army.
