The First Nebraska Cavalry had "veteran volunteered," as it was called. After a person had served in the field eighteen months, then he could "veteranize," as it was said, and enlist for three years longer and get a bounty of $300, so that soldiers and sometimes regiments "veteranized." The First Nebraska was a regiment in which the men had veteranized to such an extent that it was reorganized as a veteran regiment, and bore the name of veteran volunteer in the title of the regiment. The incursions of the Indians, and the vast damages which they had done in Nebraska, raised such an outcry that the Government had to send Nebraska troops home for the protection of Nebraska, the same as a portion of our regiment was stationed in Iowa. And so it happened that the "First Nebraska Veteran Volunteer Cavalry" was drawn from the field, and the Confederacy, and sent out to fight Indians in the Northwest. The [[7th Regiment Iowa Volunteer Cavalry|7th Iowa Cavalry]] and the First Nebraska got along together very well.Chapter 32, Ware, Eugene, [http://www.kancoll.org/books/ware/ew_main.htm The Indian War of 1864:] Being a Fragment of the Early History of Kansas, Nebraska, Colorado and Wyoming", Crane & Company (1911).
