Delta Troop, 4th Cavalry began as Delta Troop, 1st Cavalry and was organized in June of 1855 at Jefferson Barracks, Missouri. The period between July 1855 and the start of the Civil War saw D Troop and the rest of the 1st Cavalry operating in Kansas and against Indians in what would become the states of Oklahoma and Colorado. In August of 1861, the cavalry regiments of the Regular Army were renumbered and reorganized. This resulted in the 1st Cavalry becoming the 4th Cavalry.

The 4th Cavalry served in the Western Theater throughout the Civil War. D Troop took part in many of the regiment’s engagements culminating with the Tennessee Campaign in 1864 and Wilson’s Raid through Macon and Selma, Georgia, in 1865. The men of the 4th Cavalry could be proud of their war record, but history would not allow them much time to rest on their laurels. New duties beckoned and new challenges waited. D Troop would spend much time in the occupied South carving out the fighting reputation that was second to none in the Army of the time. On a cold snow-covered plain on October 23, 1876, D Troop, reinforcing General Crook’s forces, surrounded and disarmed Red Cloud’s Sioux village without a single loss of life. D Troop spent the remainder of the decade in New Mexico and Arizona. D Troop spent the last decade of the 19th Century occupying a variety of posts in the Pacific Northwest. This quiet duty ended with a deployment to the Philippines in July of 1899.

From its formation until the turn of the century, D Troop formed a steady and reliable part of the 4th Cavalry. It was present at most of the regiment’s most famous engagements, distinguishing itself time and again both in battle and on long campaigns in the heat of the Southwest and the cold of the northern plains. On 11 May 1959, D Troop was redesignated 4th Reconnaissance Squadron, 4th Cavalry. 4th Squadron, 4th Cavalry was inactivated 13 December 1965. It was once again reactivated as D Troop, 4th Cavalry on 25 February 2000 as the Brigade Reconnaissance Troop. D Troop continued its operational heritage when it deployed to Kuwait in August 2001 as part of Intrinsic Action.

To this day Delta Troop remains “Prepared and Loyal!”
