Niels Knudsen from Stavanger, Norway. He joined the WI 15th Infantry, Company A. The men of the company called themselves the "St. Olaf's Rifles." They were also known as the "Sailor Company" because of the large number of seamen in its ranks, and as the "Chicago Company" because so many of its members were residents of that city. The army listed him as living in Chicago, IL, age 27, and unmarried. He enlisted for three years on October 28, 1861 at Chicago, and mustered on November 15, 1861, at Madison, WI, as a Private (Menig). Knudsen was under arrest at Mississippi River Island No. 10 on May 17, 1862, and disappeared from jail on July 11, 1862 and was never mustered out. After the war, he was said to be living in Norse, TX.
