A couple of requests for information regarding the 58th Infantry Regiment's involvement in the Aleutian Islands during WWII found me with no answers. I searched through two dozen books and the Internet at length looking for information about the 58th Infantry with no luck. Ardon Smith (WWII Attu) came through with this description of the 58th's history in the Aleutians:
