Colonel Hans Christian Heg of the Norwegian pioneer settlement at Muskego, Wisconsin, led a regiment of immigrant soldiers, recruited chiefly in the Badger State but also in Illinois, Iowa, and Minnesota, to the battlefield of the South in the Civil War. This volume is made up mainly of the letters, hitherto unpublished, hat he wrote to his wife and children from January 16, 1862, shortly after the organization of the Fifteenth Wisconsin Volunteer Infantry, to September 188, 1863, the day before the battle of Chickamauga, in which, as commander of the brigade, he met his death. Some of these personal records are presented in full, some in the form of abstracts, and some merely through excerpts. Supplementing them are a few communications from Colonel Heg that found their way into the columns of a Milwaukee newspaper. A biographical essay supplies a background for the interpretation of the documents.
