11th Infantry Regiment 13th Infantry Regiment

The 12th Infantry Regiment is a unit of the United States Army. The 12th Infantry has fought in seven wars from the Civil War to the Global War on Terrorism and has been awarded four Presidential Unit Citations, five Valorous Unit Awards, a Joint Meritorious Unit Award, two citations in the Order of the Day of the Belgian Army, three Republic of Vietnam Cross of Gallantry, the Republic of Vietnam Civil Action Honor Medal First Class, a Meritorious Unit Commendation, and the Belgian Fourragere.


War of 1812

Thomas Parker was colonel of the regiment in 1812.[2] The 12th was raised in Virginia and fought in the Canadian and Chesapeake theaters of the War of 1812.[3]

Civil War

Less than a month after the first shots of the Fort Hamilton in New York. The battalion saw extensive combat during the Civil War, participating in twelve campaigns with the Army of the Potomac.

During the Peninsula Campaign, the 12th Infantry distinguished itself in its first combat action at the Battle of Gaines' Mill in June 1862, while sustaining fifty percent casualties. The regiment also participated in such historic battles as Antietam, Fredericksburg, Chancellorsville, Gettysburg and six additional campaigns culminating with the Siege of Petersburg, Virginia, from late summer 1864 through April 1865 and the war's end.

Indian Wars

The battalion was reorganized and redesignated as the 12th Infantry Regiment on 7 December 1866. In the 1870s, the regiment took part in three campaigns of the Indian Wars; against the Modoc tribe in California during 1872-1873, against the Bannocks in the Northwest in 1878, and against the Sioux at Pine Ridge, South Dakota from 1890-91. During these campaigns, six soldiers performed acts deemed worthy of the Medal of Honor.

Spanish-American War and Philippine-American War

During the Spanish–American War, the 12th Infantry was sent to Cuba, in June 1898, and participated in the storming of the Spanish fortress in the Battle of El Caney, where the 12th had the distinction of capturing the Spanish colors.

At the conclusion of the War with Spain, the regiment was immediately deployed in February 1899 to the Philippine Islands to reinforce other Army units fighting elements of the Filipino Army that resisted the United States after they defeated the Spanish at the Battle of Manila. There, the regiment participated in three campaigns (Malolos, Tarlac, and Luzon 1899) of what was to be known as the Philippine-American War and then served as garrison troops, not returning to the United States until 1912.

Garrison duty

On 17 December 1917 the 12th Infantry was assigned to the 8th Division at Camp Fremont, California, but was not sent overseas in World War I. In August 1918 most of the regiment volunteered for duty in Siberia and the regiment was skeletonized until replacements were received and trained. As part of the 15th Infantry Brigade, the regiment moved to its pre-embarkation staging location at Camp Mills, New York, between 23 October and 31 October 1918, but entrained while quarantined at Camp Fremont for Spanish influenza. After its arrival, the regiment remained in strict quarantine until after its convoy had sailed, and was not released until 11 November, the day the armistice ended the war.

The regiment remained assigned to the 8th Division until 15 August 1927 when it was reassigned to the 4th Motorized Division.

World War II

The 12th Infantry Regiment was reorganized as a motorized infantry regiment on 29 September 1942. Less than a year later, on 1 August 1943, the 12th was reorganized as a standard infantry regiment when the 4th Division was converted from motorized to dismounted infantry. The regiment along with the rest of the 4th Infantry Division arrived in England on 29 January 1944. On D-Day, 6 June 1944, the 12th Infantry saw its first action of the war when, as part of the 4th Infantry Division, it spearheaded the assault landing on Utah Beach under the command of Colonel Russell "Red" Reeder. Between 9 and 12 August 1944, the regiment helped defeat the German Operation Lüttich. The regiment fought in five European campaigns through France, Belgium, Luxembourg and Germany. The 12th Infantry was awarded the Presidential Unit Citation for valor in action at Luxembourg during the Battle of the Bulge. The regiment was also awarded the Belgian Fourragere. After Germany's surrender, the 12th Infantry, along with the 4th Infantry Division, returned to the United States on 12 July 1945 and was inactivated 27 February 1946 at Camp Butner, North Carolina. During this time famed author J. D. Salinger served with the unit.

Cold War

On 15 July 1947, the 12th Infantry Regiment was reactivated as a training regiment when 4th Infantry Division was given the mission of basic training at Fort Ord, California. In July 1951, the 4th Division was returned to line status and rotated to Germany as part of Operation Gyroscope. In 1956, the Division returned to the United States and was stationed at Fort Lewis, Washington.

In 1957, the Army decided that in the era of battlefield atomic weapons, tactical infantry regiments were obsolete. To preserve the historic infantry regiments the Army set up the 79th Infantry Division.

By the time the Berlin Wall went up in August 1961, the 2nd Battle Group, 12th Infantry along with the rest of the 1st Infantry Division had been transferred back to Fort Riley, Kansas. To reinforce NATO, the 1st Division was directed to begin Operation Long Trust whereby the individual battle groups were rotated on temporary duty to West Germany. In July 1962, the 2nd Battle Group, 12th Infantry was airlifted to West Germany where it undertook several months of tactical training and testing at Wildflecken, West Germany. It was then ordered to proceed to Berlin overland through East Germany using the Helmstedt-Berlin autobahn to test the Warsaw Pact's willingness to allow NATO forces to continue to use it. Arriving without incident in Berlin to reinforce the U.S. Army's Berlin Brigade, the 2nd Battle Group was quartered at Andrews and McNair Barracks. Because of the ongoing Cuban missile crisis, the battle group was almost on constant alert in October 1962.

In 1963, the Army concluded that the battle group was not the answer and reorganized the infantry and airborne divisions into a quasi-regimental structure of three brigades of three infantry battalions each. Consequently on 1 October 1963, the 2nd Battle Group, 12th Infantry was reorganized and redesignated as the 2nd Battalion, 12th Infantry and reassigned to the 4th Infantry Division at Fort Carson, Colorado where it joined the 1st and 3rd Battalions of the 12th Infantry.


The three 12th Infantry battalions deployed to Vietnam with the 4th Division from August through October 1966. The 3rd Brigade, 4th Division, to which the 2nd Battalion, 12th Infantry was assigned, set up base camp at Dầu Tiếng in III Corps while the rest of the 4th Division was assigned to the Vietnamese Highlands in II Corps alongside the 3rd Brigade of the 25th Division which had arrived in December 1965. On 1 August 1967, the two divisions swapped 3rd Brigades. Subsequently, the 2nd Battalion, 12th Infantry served with the 25th through 10 of the Battalion's 11 Vietnam campaigns and received the Presidential Unit Citation for gallantry in action at Suoi Tre. As part of the U.S. draw-down, the 2nd Battalion, 12th Infantry was returned to Fort Lewis, WA, and inactivated on 17 April 1971.

The 4th Battalion, 12th Infantry was activated and assigned to the Fort Carson, CO. Three soldiers from the 1st Battalion, one from the 2nd Battalion, two soldiers from the 4th Battalion, and one soldier from the 5th Battalion, were awarded the Medal of Honor.

Post Vietnam

The CARS system was replaced by the US Army Regimental System in 1985 when the army contemplated shifting to a unit replacement system. Under the new system four battalions of the 12th Infantry were activated. The 1st and 2nd Battalions were assigned to the 4th Infantry Division at Fort Carson and the 3rd and 4th Battalions were assigned to the 8th Infantry Division in Germany. The concept was for members of the regiment to spend the majority of their army careers rotating between assignments with regimental battalions at Fort Carson and in Germany.

By the early 1990s, the Army draw-down and its expanding worldwide peace-keeping commitments led to a decision to scrap the unit replacement concept before it was fully implemented. The 3rd and 4th Battalions were transferred to the 1st Armored Division and served in Bosnia before being inactivated in Germany in 1997.

Operation Sea Signal

The 1st Battalion, 12th Infantry Regiment "Warriors" of the 4th Infantry Division deployed from 29 August 1994 - 25 February 1995 to Guantanamo Bay, Cuba in support of Joint Task Force 160 to provide refugee camp security at Camp Alpha, Camp Bravo, Camp Golf, Camp Mike, Camp Quebec, Camp Romeo, Camp Sierra, and Camp X-Ray. The unit also served as a quick reaction force to quell any refugee uprisings, built refugee housing camp facilities, escorting refugees for medical treatment, repatriation of Haitian refugees, distribution of food and supplies, and main base security.The battalion was housed in a tent city located on the football field of the base high school with the exception of Charlie Company who was housed in tents in the nursery. Awards for participation in Joint Task Force 160 include the Humanitarian Service Medal, and the Joint Meritorious Unit Award. The 1st Battalion was inactivated at Fort Carson in September 1995, after returning from deployment to Guantanamo Bay as a part of Operation Sea Signal. The 2d Battalion was then reflagged as the 1st Battalion in 1996 after having soldiers from the inactivated 1st Battalion added to the ranks.

Operation Iraqi Freedom

The 1st Battalion, 12th Infantry Regiment was formerly assigned to the 3d Brigade Combat Team of the U.S. 4th Infantry Division at Fort Carson and deployed with the 3d BCT in March 2003 in support of Operation Iraqi Freedom I. From May 2003 - February 2004, the battalion and elements of 1-68 Armor and 4th Engineers was attached to 173rd Airborne Infantry Brigade while B/1-12 remained with 1-68 Armor under 3rd Brigade/4th Infantry Division. The battalion redeployed back to Fort Carson in March 2004. As a result of the transformation of the brigade to the modular concept, elements of the battalion were changed to a cavalry squadron, the 2nd Squadron, 9th Cavalry Regiment in November 2004. 1st Battalion, 12th Infantry Regiment was reactivated at Fort Hood as part of the 4th BCT, 4th Infantry Division and deployed to Baghdad, Iraq, in fall of 2005 in support of Operation Iraqi Freedom. It was replaced in the fall of 2006 by the 2d BCT, 2d Infantry Division from Fort Carson. This unit was temporarily assigned to 1st Cavalry Division to which the 2d Battalion, 12th Infantry Regiment was attached until February 2007 when the 4th BCT, 1st Infantry Division was assigned tactical control of Baghdad. 1st and 2d Battalions, 12th Infantry Regiment are currently assigned to 4th BCT, 4th Infantry Division, Fort Carson, Colorado.

Operation Enduring Freedom

In December 2001, Companies B and C of the 1st Battalion deployed to Kuwait in support of Intrinsic Action 01-02 and later in support of Operation Enduring Freedom. Elements of other units from within the 3d BCT, 4th Infantry Division made up the remainder of Task Force 1-12. The task force redeployed to Fort Carson in May 2002.

In May 2009, 1st and 2nd Battalions, 12th Infantry Regiment, 4BCT, 4th Infantry Division, deployed to Afghanistan in support of Operation Enduring Freedom X. 1st Battalion was based in the Arghandab River Valley, west of Kandahar City, for the latter eight months of the deployment. Task Force 1-12's area of responsibility was referred to as the "Heart of Darkness" due to its significance as the birthplace of the Taliban, and also due to the inherent complexity of their mission. Much of their fighting was conducted in notoriously dense grapefields, which provided excellent concealment for insurgent forces. The 2nd Battalion was based in the Pech River Valley, Kunar Province, home to the Korengal, Waygal, Shuriak, and Wata Pour Valleys. During its time in the Pech Valley, the 2nd Battalion saw heavy fighting throughout their area of responsibility at the foothills of the Hindu Kush mountains. In June 2010, Task Force 1-12 and Lethal Warrior (2-12), 4th BCT, 4 ID redeployed to Fort Carson, Colorado, after 12 months in Afghanistan.

In March 2012, 1st and 2nd Battalions, 12th Infantry Regiment, 4BCT, 4 ID, again deployed to Afghanistan in support of Operation Enduring Freedom. This time, both battalions were based out of Regional Command East. Both battalions returned by December, 2012, after 9-months in Afghanistan.

Several photographers and journalists were embedded with the 1st Battalion 12th Infantry Regiment during their 2009-2010 tour to Kandahar. A series of articles published by David Philipps in the Colorado Springs Gazette chronicles the 2nd Battalion of the 12th Infantry Regiment.[5] The series inspired the book Lethal Warriors - When the New Band of Brothers Came Home.[6] which follows the lives of Lethal Warriors members after returning to the United States.
