1st Infantry Division (United States)


The 1st Infantry Division is a combined arms division of the United States Army, and is the oldest continuously serving in the Regular Army. It has seen continuous service since its organization in 1917 during World War I. It was officially nicknamed "The Big Red One" after its shoulder patch and is also nicknamed "The Fighting First." The division has also received troop monikers of "The Big Dead One" and "The Bloody First" as puns on the respective officially sanctioned nicknames. It is currently based at Fort Riley, Kansas.

World War I

The First Expeditionary Division, later designated the 1st Infantry Division, was constituted on 24 May 1917, in the Regular Army, and was organized on 8 June 1917, at Fort Jay, on Governors Island in New York harbor under the command of Brigadier General William L. Sibert, from Army units then in service on the Mexico–United States border and at various Army posts throughout the United States. The original table of organization and equipment included two organic infantry brigades of two infantry regiments each, one engineer battalion; one signal battalion; one trench mortar battery; one field artillery brigade of three field artillery regiments; one air squadron; and a full division train. The total authorized strength of this TO&E was 18,919 officers and enlisted men. George S. Patton, who served as the first headquarters commandant for the American Expeditionary Forces, oversaw much of the arrangements for the movement of the 1st Division to France, and their organization in-country. Frank W. Coe, who later served as Chief of Coast Artillery, was the division's first chief of staff.
The first units sailed from New York City and Hoboken, New Jersey, on 14 June 1917. Throughout the remainder of the year, the rest of the division followed, landing at St. Nazaire, France, and Liverpool, England. After a brief stay in rest camps, the troops in England proceeded to France, landing at Le Havre. The last unit arrived in St. Nazaire 22 December. Upon arrival in France, the division, less its artillery, was assembled in the First training area, and the artillery was at Le Valdahon.
On 4 July, the 2nd Battalion, 16th Infantry, paraded through the streets of Paris to bolster the sagging French spirits. An apocryphal story holds that at Lafayette's tomb, to the delight of the attending Parisians, Captain C.E. Stanton of the division's 16th Infantry Regiment stepped forward and declared, "Lafayette, nous sommes ici! " Two days later, 6 July, Headquarters, First Expeditionary Division was redesignated as Headquarters, First Division, American Expeditionary Forces.
On 8 August 1917, the 1st Division adopted the "square" Table of Organization and Equipment, which specified two organic infantry brigades of two infantry regiments each; one engineer regiment; one signal battalion; one machine gun battalion; one field artillery brigade of three field artillery regiments, and a complete division train. The total authorized strength of this new TO&E was 27,120 officers and enlisted men.
On the morning of 23 October, the first American shell of the war was fired toward German lines by a First Division artillery unit. Two days later, the 2nd Battalion of the 16th Infantry suffered the first American casualties of the war.
By April 1918, the German Army had pushed to within of Paris. In reaction to this thrust, the division moved into the Picardy Sector to bolster the exhausted French First Army. To the division's front lay the small village of Cantigny, situated on the high ground overlooking a forested countryside. The 28th Infantry Regiment attacked the town, and within 45 minutes captured it along with 250 German soldiers. It was the first American victory of the war. The 28th was thereafter named the "Black Lions of Cantigny."
Soissons was taken by the 1st Division in July 1918. The Soissons victory was costly – 700 men were killed or wounded.. The 1st Division took part in the first offensive by an American army in the war, and helped to clear the Saint-Mihiel salient by fighting continuously from 11 to 13 September 1918. The last major World War I battle was fought in the Meuse-Argonne Forest. The division advanced a total of seven kilometers and defeated, in whole or part, eight German divisions. This victory was mainly due to the efforts of George C. Marshall, who began the war as the division's Deputy Chief of Staff before being elevated to G-3 for the entire AEF in July 1918. Combat operations ended with the implementation of the terms of the Armistice on 11 November 1918. At the time the division was at Sedan, the farthest American penetration of the war, and was the first to cross the Rhine into occupied Germany.
By the end of the war, the division had suffered 4,964 killed in action, 17,201 wounded in action, and 1,056 missing or died of wounds. Five division soldiers received Medals of Honor.
The division's dog-mascot was a mixed breed terrier known as Rags. Rags was adopted by the division in 1918 and remained its mascot until his death in 1936. Rags achieved notoriety and celebrity as a war dog, after saving many lives in the crucial Argonne Campaign by delivering a vital message despite being bombed and gassed.

World War II

Order of battle

Shortly after the German invasion of Poland, beginning World War II in Europe, the 1st Infantry Division, under Major General Walter Short, was moved to Fort Benning, Georgia, on 19 November 1939 where it supported the U.S. Army Infantry School as part of American mobilization preparations. It then moved to the Sabine Parish, Louisiana area on 11 May 1940 to participate in the Louisiana Maneuvers. The division next relocated to Fort Hamilton, Brooklyn on 5 June 1940, where it spent over six months before moving to Fort Devens, Massachusetts, on 4 February 1941. As part of its training that year, the division participated in both Carolina Maneuvers of October and November before returning to Fort Devens, Massachusetts on 6 December 1941.
A day later, on 7 December 1941, the Japanese attacked Pearl Harbor and, four days later, Germany declared war on the United States, thus bringing the United States into the conflict. The division was ordered to Camp Blanding, Florida, as quickly as trains could be gathered and winter weather permitted, and arrived on 21 February 1942. The division, now under Major General Donald C. Cubbison, was there reorganized and refurbished with new equipment, being re-designated as the 1st Infantry Division on 15 May 1942. Within a week, the division was returned to its former post at Fort Benning, Georgia, from where it was expedited on 21 June 1942 to Indiantown Gap Military Reservation for wartime overseas deployment final preparation. The division, now under the command of Major General Terry Allen, a distinguished World War I veteran, departed the New York Port of Embarkation on 1 August 1942, arrived in Beaminster in south-west England about a week later, and departed 22 October 1942 for the combat amphibious assault of North Africa.
As part of II Corps, the division landed in Oran, Algeria on 8 November 1942 as part of Operation Torch, the Allied invasion of French North Africa. Elements of the division then took part in combat at Maktar, Tebourba, Medjez el Bab, the Battle of Kasserine Pass, and Gafsa. It then led the Allied assault in brutal fighting at El Guettar, Béja, and Mateur. The 1st Infantry Division was in combat in the Tunisian Campaign from 21 January 1943 to 9 May 1943, helping secure Tunisia. The campaign ended just days later, with the surrender of almost 250,000 Axis soldiers. After months of nearly continuous fighting, the division had a short rest before training for the next operation.

In July 1943, the division took part in the Allied invasion of Sicily, codenamed Operation Husky, still under the command of Major General Allen. Lieutenant General George S. Patton, commanding the U.S. Seventh Army, specifically requested the division as part of his forces for the invasion of Sicily. It was still assigned to the II Corps. In Sicily the 1st Division saw heavy action when making amphibious landings opposed by Italian and German tanks at the Battle of Gela. The 1st Division then moved up through the center of Sicily, slogging it out through the mountains along with the 45th Infantry Division. In these mountains, the division saw some of the heaviest fighting in the entire Sicilian campaign at the Battle of Troina; some units losing more than half their strength in assaulting the mountain town. On 7 August 1943, Major General Allen was relieved of his command by Lieutenant General Omar Bradley, then commanding the II Corps. Allen was replaced by Major General Clarence R. Huebner who was, like Allen, a decorated veteran of World War I who had served with the 1st Infantry Division throughout the war.
When that campaign was over, the division returned to England, arriving there on 5 November 1943 to prepare for the eventual invasion of Normandy. The 1st Infantry Division and one regimental combat team from the 29th Infantry Division comprised the first wave of troops that assaulted German Army defenses on Omaha Beach on D-Day. The division had to run 300 yards to get to the bluffs, with some of the division's units suffering 30 percent casualties in the first hour of the assault, and secured Formigny and Caumont in the beachhead by the end of the day. The division followed up the Saint-Lô break-through with an attack on Marigny, 27 July 1944.
The division then drove across France in a continuous offensive, reaching the German border at Aachen in September. The division laid siege to Aachen, taking the city after a direct assault on 21 October 1944. The 1st Division then attacked east of Aachen through the Hürtgen Forest, driving to the Ruhr, and was moved to a rear area 7 December 1944 for refitting and rest following 6 months of combat. When the German Wacht Am Rhein'' offensive was launched on 16 December 1944, the division was quickly moved to the Ardennes front. Fighting continuously from 17 December 1944 to 28 January 1945, the division helped to blunt and reverse the German offensive. Thereupon, the division, now commanded by Major General Clift Andrus, attacked and again breached the Siegfried Line, fought across the Ruhr, 23 February 1945, and drove on to the Rhine, crossing at the Remagen bridgehead, 15–16 March. The division broke out of the bridgehead, took part in the encirclement of the Ruhr Pocket, captured Paderborn, pushed through the Harz Mountains, and was in Czechoslovakia, fighting at Kynšperk nad Ohří, Prameny, and Mnichov when the war in Europe ended. Sixteen members of the division were awarded the Medal of Honor during World War II.

They were later joined by 1–5 Field Artillery in northern Iraq in late spring 2011.
2nd Heavy Brigade Combat Team deployed to Baghdad, Iraq in November 2010 in an advise and assist role as part of Operation New Dawn under the command of COL Paul T. Calvert. The brigade HQ was located at Victory Base Complex, where it was co-located within the USD-C Division HQ building and shared the same TOC. This unique C2 relationship earned the brigade the moniker of the "Luckiest Brigade in the Army" from the USD-C commander. The brigade was placed under USD-C and was single-handedly responsible for the entire province of Baghdad. As the brigade responsible for the "center of gravity" for United States Forces-Iraq, the 2nd "Dagger" Brigade was responsible for advising and assisting 50% of the Iraqi security forces within Iraq to include two Iraqi corps HQ and seven Iraqi divisions and 50,000 Iraqi policemen.
The 1st Battalion, 18th Infantry Regiment, commanded by LTC John Cross, was located at Camp Taji and FOB Old MOD. They were partnered with the 9th and 11th IA Divisions. 1st Battalion, 7th FA, commanded by LTC Andrew Gainey, was located at JSS Loyalty. They were partnered with the 1st Federal Police Division. 1st Battalion, 63rd Armored, commanded by LTC Michael Henderson, was located at JSS Deason, Muthana Airfield, and VBC. They were partnered with the 6th and 17th IA Divisions. 5th Squadron, 4th Cavalry, commanded by LTC Mathew Moore was located at JSS Falcon. They were partnered with the 2nd and 4th FP Divisions. The Special Troops Battalion, commanded by LTC Shilisa Geter, was located at VBC and partnered with the Baghdad Police Directorate. Meanwhile, due to the drawdown of US forces and the redeployment of theater-level sustainment brigades, the 299th BSB, commanded by LTC Dale Farrand, assumed the area support mission for all DOD and DOS elements within the province of Baghdad in addition to supporting the Dagger Brigade.
Significant events during this deployment included the resumption of attacks by the Sadrist movement and other Iranian-backed militia, the subsequent operations that stopped those attacks, the rearward passage of lines of USD-North as they redeployed through Baghdad, the organization and training of divisional field artillery regiments for the IA divisions, the fielding of M1 tanks for the 9th IA Division, and the hand-over of all US facilities within Baghdad to the Government of Iraq or elements of the US State Department. During this deployment the brigade simultaneously trained ISF units to the point of conducting Iraqi-led battalion CALFEXs, advised ISF units as they conducted hundreds of Iraqi-led raids which disrupted the attacks of Iranian-backed militia, while also conducting unilateral and combined force protection operations to ensure the security of US bases and redeploying US forces. The brigade experienced nine KIAs during this deployment, the majority of which resulted from a single IRAM attack conducted against JSS Loyalty by Iranian-backed militia on 6 June 2011. The brigade departed Iraq in November 2011 after having turned the majority of the city of Baghdad over to complete Iraqi control.

Afghanistan 2011–2012

From 1st Heavy Brigade Combat Team, 1st Battalion, 16th Infantry and 4th Squadron, 4th Cavalry deployed to Afghanistan in the winter of 2011, with 2nd Battalion, 34th Armor later deploying in the spring of 2011. 1–16 IN was assigned to support the combined joint special task force, the Iron Rangers were deployed to 58 remote locations across Afghanistan.

The brigade conducted Operations Tofan I and II. Tofan I's mission was to disrupt insurgent safe havens in the Musa Khel region of Khowst province, improve the ability for the government to reach the people there and gather intelligence for planning future operations. Tofan II's mission was to establish contact with the insurgents, disrupt their logistics, and reduce any material or moral support from the local population. Movement to the extremely remote area, which featured narrow or non-existent roads set among mountains, included mounted and dismounted soldiers who also had to be aware of the need to control the key terrain features around Suri Kheyl.

Afghanistan 2012–2013

The 1st Infantry Division headquarters deployed to Bagram, Afghanistan on 19 April 2012 as part of Operation Enduring Freedom XIII after receiving responsibility for Regional Command from 1st Cavalry Division.

This will be the first Division HQ deployed in Iraq since withdrawal back in 2011. Among the soldiers sent over approximately 200 will be stationed in Baghdad, where they will make up close to half of US troops deployed.
In mid-October 2016 the US Army announced it will deploy about 500 soldiers from the 1st Infantry Division Headquarters to Iraq in the fall of 2016. Troops will assume the role of Combined Joint Forces Land Component Command-Iraq in support of Operation Inherent Resolve.

Operation Freedom's Sentinel

In late July 2016, the U.S. Army announced that it will send 800 soldiers from 1st Combat Aviation Brigade, 1st Infantry Division, to Afghanistan to support Operation Freedom's Sentinel – the U.S. counter-terrorism operation against the remnants of al-Qaeda, ISIS–K and other terror groups. The brigade will deploy with its AH-64 Apache attack helicopters and UH-60 Black Hawk utility helicopters sometime before October 2016.

In April 2017, Military.com reported that approximately 4,000 soldiers from the 2nd Armored Brigade Combat Team, 1st Infantry Division will deploy to Europe as part of Operation Atlantic Resolve, replacing the 3rd Armored BCT, 4th Infantry Division in a regular rotation of forces. The unit deployed in September 2017 and redployed in June 2018, serving throughout Eastern Europe conducting readiness and inter-operability training with NATO Allies to assure U.S. Allies and deter aggression. The Division Headquarters deployed part of its headquarters in March 2018 to Poznan, Poland, to serve as the U.S. Army Europe's Mission Command Element forward providing mission command of the Regionally Aligned Forces serving in Atlantic Resolve. They are scheduled to remain until June 2020. In January the division's 1st Armored Brigade Combat Team and 1st Combat Aviation Brigade deployed to Eastern Europe in Support of Operation Atlantic Resolve with the mission of building readiness, assuring Allies, and deterring aggression on the continent.

Insignia

No credible source states how the insignia of the 1st Infantry Division originated in World War I. There are two theories as to how the idea of the patch came about. The first theory states that the 1st Division supply trucks were manufactured in England. To make sure the 1st Division's trucks were not confused with other allies, the drivers would paint a huge "1" on the side of each truck. Later, the division engineers would go even farther and put a red number one on their sleeves.
The second theory claims that a general of the division decided the unit should have a shoulder insignia. He decided to cut a red numeral "1" from his flannel underwear. When he showed his prototype to his men, one lieutenant said, "the general's underwear is showing!" Offended, the general challenged the young lieutenant to come up with something better. So, the young officer cut a piece of gray cloth from the uniform of a captured soldier, and placed the red "1" on top.

Music

Band

The 1st Infantry Division Band is the musical ambassador for the division that performs for military ceremonies at Fort Riley and the surrounding communities in the Midwest. The 38-member band contains the Concert Wind Ensemble, the Marching Band, a Seated Ceremonial Band as well as other specialized ensembles. The band was notably involved in the Thunder Road incident in Vietnam, during which Major General John Hay ordered the band to march down "Thunder Road", for one mile while playing the Colonel Bogey March. The road, which was critical to the division's operations, was under the control of a North Vietnamese Army regiment. Confused by the action, the regiment withdrew from the area, with the band fulfilling a remarkable combat mission without firing a shot. In 2008, A parachutist injured three members of the band after crashing into them following getting off course during military review.

Song

According to the 1st Infantry Division history, the song was composed in 1943 by Captain Donald T. Kellett, who retired after a 30-year career as a colonel and died in 1991.

Current structure

1st Infantry Division consists of the following elements: a division headquarters and headquarters battalion, two armored brigade combat teams, a division artillery, a combat aviation brigade, a sustainment brigade, and a combat sustainment support battalion.
