During Westward Expansion, the regiment provided escort for the early western settlers and maintained peace on the American frontier.

The men enlisted for the usual term of five years and privates received $13 per month, plus room, meals, and clothing.

[citation needed] The mustering, organized by Maj. Francis Moore, 65th U. S. Colored Infantry, formed the nucleus of the enlisted strength, and was obtained from New Orleans and its vicinity.

[3] By the end of March 1867, the 9th Cavalry was at nearly full strength with a total of 885 enlisted men, or an average of over 70 to a Troop, and was ordered to San Antonio, Texas, where it arrived early in April for three months of training.

The men at this point still had not been introduced to the Articles of War, and two soldiers convicted to death were pardoned and restored to duty.

While in Texas, the troops battled intermittently with Apaches, Kiowas, and Comanches, escorted mail, and rescued civilians from Native American captivity.

On 26 December 1867, K Troop lost three troopers at Fort Lancaster in an encounter with an estimated force of 900 Native Americans and white outlaws.

The 6th Cavalry was ordered in by President Benjamin Harrison to quell the violence and capture the band of hired killers.

The Buffalo Soldiers responded within about two weeks from Nebraska, and moved the men to the rail town of Suggs, Wyoming, creating "Camp Bettens" despite a hostile local population.

It had been proposed in 1897 at the "Cavalry and Light Artillery School" at Fort Riley that West Point cadets learn their riding skills from the black non-commissioned officers who were considered among the best.

[14] The regiment departed Manila on 12 October 1922 on the troopship USAT Logan and arrived on 11 November 1922 at San Francisco, California.

The battalion was activated at Camp Polk, Louisiana on 1 November of that year and inactivated at Fort Knox on 10 April 1956.

[23] The squadron was reactivated in April, 1986, at Ladd Army Airfield, Hangar 2,Fort Wainwright, Alaska, with the 6th Infantry Division, where it served during the later years of the Cold War.

In 1977 D-Troop under the leadership of Cpt Maldonado and Medal of Honor Recipient Frank D. Miller attended the Jungle Operations Training Center program at Ft. Sherman, Panama Canal with one medic from the HHT.

In 1977 the HHT, A-Troop, B-Troop were moved 40 miles away to Ft Stewart where it was re-designated as an Air and Armored Cavalry.

While D-Troop maintained the Rotary Wings Aircraft and Cavalry Recon Scouts (Airmobile – Air Assault group), A-Troop was given APC's armored personnel carriers and B-Troop had many of the larger track vehicles.

(As a side note, the Third Brigade was led by then Colonel George Casey Jr. and the 1st Cavalry Division was led by future Democratic presidential candidate General Wesley Clark Sr.) 1-9 Cavalry was a rapidly deployable infantry unit of action which deployed abroad several times in the decade; to thwart aggressive and hostile maneuvers of the Iraqi Army.

1993: 1994: 1995: 1996: 2000 Today, the units of the 9th United States Cavalry Regiment provide RSTA (reconnaissance, surveillance, and target acquisition) capabilities forward of enemy lines and supply infantrymen as sniper and long range surveillance teams for use as special reconnaissance in the area of combat operations.

These small Army reconnaissance units, provide valuable real-time intelligence about an enemy nation, including its leaders, combat capabilities etc.

Troop B ("Bloody Knife"), 9th Cavalry, 3rd Brigade, 4th Infantry Division, was deployed from Fort Carson, Colorado, to Iraq in April 2003.

The lead elements of the Brigade Reconnaissance Troop (BRT) then crossed into Iraq, covering a distance of over 300 kilometers.

The Bloody Knife Troop became the quick reaction force for one of the largest logistics bases in Iraq while still conducting operations where ever the brigade needed them.

The unit was featured as the command of LTC Bill Kilgore in the classic Vietnam War movie Apocalypse Now.

The 1st Squadron, 9th Cavalry Regiment (1-9th Cav), began deployment to Iraq in September 2003 in support of Operation Iraqi Freedom.

[31] During their first deployment, 124 Purple Heart medals were awarded to Task Force 1-9 soldiers, who operated in one of the most dangerous sections of Iraq, including the 2004 Battles of Sadr City and Haifa street.

In October 2006, the 1st Squadron, 9th Cavalry Regiment, began its second deployment to Iraq from Fort Bliss, Texas, in support of Operation Iraqi Freedom, along with the rest of 4th Brigade Combat Team, 1st Cavalry Division, to work alongside units of the 25th Infantry Division to comprise Task Force Lightning.

In June 2008, 1-9th Cav deployed to OIF 08-10 to CSC SCANIA and assumed responsibilities for MSR TAMPA and the cities of Hamza, Qasim, Hashimiyah, Ash Shumali and other smaller towns from 3rd Squadron, 73rd Cavalry of the 1st Brigade Combat Team, 82nd Airborne Division.

During Operation Desert Storm, it served as the 24th Infantry Division's Divisional Cavalry Squadron and was based at Fort Stewart, Georgia.

In 2009 the squadron again deployed to Iraq, this time to Kirkuk Province for OIF 09-10, where it was responsible for the security, stability, and reconstruction of the Daquq district and the Taza, Laylan, and Rashaad sub-districts.

The squadron also helped to balance ethnic tensions through the training and equipping Iraqi security forces, improvement of essential services, and the support and promotion of the legitimate government.
