This muster roll of Company E of the First Mounted Rangers dated December 10th, 1862, lists Captain Eugene St. Julien Cox of St. Peter as its commander. The roll also contains the names of additional officers and the names of non-commissioned officers. 75 men are sequentially numbered as privates, and two additional names, without numbers, were apparently added later to the list.
On December 27th, 1862, Phiney Wells signed this document in St. Peter to enlist in the First Mounted Rangers. Wells stated that he was born in New York and that he was 25 years and eight months old. He listed his occupation as a farmer. Wells had blue eyes, dark hair, a light complexion, and was 5 feet 10 inches tall. The document was signed by D.R. Kennedy, who was the quartermaster of the regiment. Wells was obligated to serve for up to 12 months.
This document, dated May 11th, was sent to Eugene St. Julien Cox of St. Peter, who was the Captain of Company E of the First Mounted Rangers. The document addressed Cox as a major, but various records indicate that his highest rank was that of captain. Cox was ordered to include Sibley County in the sub-district for which he was responsible. He was also informed that a new squad had been organized in New Ulm, and that ""trappers report Indians plenty west of here."" The letter was sent from Mankato by Second Lieutenant and Adjutant George A. Clarke. The document appears to have an 1865 date, but Cox served from December 10, 1862, until November 11, 1863, and Clarke served from December 20, 1861, until December 20, 1864. It therefore appears that the document was sent in 1863.
