List of military units raised by the state of Indiana during the American Civil War.
Note: Cavalry regiments also had infantry designations.
Note: The 1st, 2nd, 3rd, 4th and 5th Regiments Indiana Volunteer Infantry were units that served in the Mexican–American War.
The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army by an act of Congress on 3 August 1861. This act converted the U.S. Army's two regiments of dragoons, one regiment of mounted riflemen, and two regiments of cavalry into one branch of service. The cavalry branch transitioned to the Armored Forces with tanks in 1940, but the term "cavalry", e.g. "armored cavalry", remains in use in the U.S. Army for mounted reconnaissance, surveillance, and target acquisition (RSTA) units based on their parent Combat Arms Regimental System (CARS) regiment. Cavalry is also used in the name of the 1st Cavalry Division for heraldic/lineage/historical purposes. Some combined arms battalions are designated as armor formations, while others are designated as infantry organizations. These "branch" designations are again, heraldic/lineage/historical titles derived from the CARS regiments to which the battalions are assigned.
XXII Corps was a corps in the Union Army during the American Civil War. It was created on February 2, 1863, to consist of all troops garrisoned in Washington, D.C., and included three infantry divisions and one of cavalry. Many of its units were transferred to the Army of the Potomac during Grant's Overland Campaign.
The Indiana National Guard is the armed force of the state of Indiana. It consists of the Indiana Army National Guard and the Indiana Air National Guard, and is part of the larger Army National Guard and the Air National Guard. With roots dating back to 1801, Indiana units first served in a national conflict in 1846 during the Mexican–American War, and were reorganized into their current configuration in 1903. Since then the guard has served at home and abroad as a part of multiple wars, disaster relief actions, and putting down strikes and riots.
The 3rd Indiana Cavalry Regiment, also designated the 45th Indiana Infantry Regiment or the 45th Indiana Volunteers was a military unit from the U.S. state of Indiana that participated in the American Civil War. It consisted of two separate "wings" that never operated together:
In the United States (US) Department of Defense, a beret flash is a shield-shaped embroidered cloth that is 2.25 in (5.72 cm) tall and 1.875 in (4.76 cm) wide with a semi–circular base that is attached to a stiffener backing of a military beret. These flashes—a British word for colorful cloth patches attached to military berets—are worn over the left eye with the excess cloth of the beret shaped, folded, and pulled over the right ear giving it a distinctive appearance. The embroidered designs of the Army's beret flashes represent the heraldic colors and patterns of a unit with a unique mission or represent the Army overall. The Air Force's beret flashes represent their Air Force Specialty Code (AFSC) or their assignment to a unit with a unique mission. Joint beret flashes—such as those worn by the Joint Communications Support Element and the Multinational Force and Observers—are worn by all who are assigned, given their uniform regulations allow.
The 39th Regiment Indiana Infantry was an infantry regiment that served in the Union Army during the American Civil War. The regiment fought at Shiloh, Corinth, and Stones River. In April 1863 the unit acquired horses and became mounted infantry, serving in the Tullahoma campaign and at Chickamauga. On October 15, 1863, the unit was renamed the 8th Indiana Cavalry Regiment.
The 6th Regiment Indiana Cavalry was a cavalry regiment that served in the Union Army during the American Civil War.
The 623rd Field Artillery Regiment is a single-battalion unit of the Kentucky Army National Guard. The unit draws its lineage from cavalry and infantry units of the Kentucky Militia formed in 1846 for service in the Mexican–American War. Its antecedents include units that served on both sides of the American Civil War as well as those that fought for the United States in the Spanish–American War, World War One and World War Two. The unit was first designated as the 623rd Field Artillery Battalion in 1947, serving under that name in the Korean War. It was part of the 138th Artillery Regiment in the 1960s before becoming the 623rd Artillery Regiment in 1969 and the 623rd Field Artillery Regiment in 1972. The unit served in the Gulf War as a self-propelled artillery unit; it is now equipped with the M142 HIMARS system.
