1st Cavalry Regiment (United States) - Origins

Origins

The "United States Regiment of Dragoons" was organized by an Act of Congress approved 2 March 1833. It became the "First Regiment of Dragoons" when the Second Dragoons were raised in 1836. With the outbreak of the Civil War and the War Department's desire to redesignate and reorganize its mounted units, its designation was changed to "First Regiment of Cavalry" by another Act of Congress on 3 August 1861. Its Headquarters were initially established at Jefferson Barracks, near St. Louis, Missouri. In the spring of 1855 two new regiments of cavalry, the First and Second Cavalry were authorized. One of these was named “The First Cavalry Regiment”, under the command of Lt. Col. Edwin Vose Sumner, the first regular American military unit to bear that name. Sumner was previously with the First Dragoons.

The regiment was initially organized as:

• Headquarters: Jefferson Barracks, Missouri: 4 March 1833
• Troop A: Nashville, Tennessee: 12 August 1833
• Troop B: Sacketts Harbor, New York: 29 July 1833
• Troop C: Louisville, Kentucky: June 1833
• Troop D: Cincinnati, Ohio: 25 July 1833
• Troop E: New York, New York: 29 June 1833
• Troop F: Jefferson Barracks: 5 December 1833
• Troop G: Jefferson Barracks: 16 January 1834
• Troop H: Jefferson Barracks: 2 March 1834

The first order announcing appointments in the regiment was dated 5 March 1833, and gave the names of the colonel, lieutenant-colonel, major, four captains and four lieutenants, stating that the organization of the regiment would be perfected by the selection of officers from the "Battalion of Rangers." In June 1834, the regiment filled its complement of officers, many of whom later became noted Civil War generals:
