As the first foreign war in U.S. history, it was the first time members of the Oregon National Guard had fought on foreign soil. The regiment also served with distinction in the Philippine–American War. At full strength, it was composed of 50 officers and 970 enlisted men. The regiment's last company was mustered out of service in August 1899.
