When the
American Civil War started, the immigrants raised an entire company and Krans was among the volunteers. He mustered into the
Union Army in Company D,
57th Illinois Volunteer Infantry Regiment. He changed his last name to Krans. The word
krans can be translated to mean wreath or garland in the Swedish language. His whole family subsequently adopted the new name. After the
Battle of Fort Donelson in Tennessee he was given a disability discharge on June 3, 1862. After the war, Krans married in 1867 and relocated to
Galva, Illinois. There he became a house painter and also did interior decorating, including the interior of Galva's Methodist and Lutheran Churches. In 1896 while he was recovering from a fall, he began painting memories and people from his youth in the Bishop Hill Colony. In his paintings, Krans documented daily life at Bishop Hill. He began painting a series of pictures that described everyday life in the early days of the colony. On the 50th anniversary of the Bishop Hill Colony, Krans donated a large portions of his paintings to the colony. Olof Krans died in
Altona, Illinois. At the time of his death he had finished more than 90 pictures. ==Memorials==
