World War II: Formation and role

The 4th Infantry Division, known as the “Ivy Division” was activated on 1 June 1940 at Fort Benning, Georgia USA. The division trained in the United States before deploying to the United Kingdom in early 1944. There, it conducted extensive amphibious training in preparation for the Allied invasion of northwest Europe. Assigned to VII Corps under First U.S. Army, the division was designated as the primary assault force for Utah Beach.

Early history

Following its activation, the division underwent extensive training in the United States as part of the Army’s expansion prior to entry into World War II. It participated in large-scale training exercises, including the Louisiana Maneuvers, which helped develop modern U.S. infantry tactics.

The division departed for overseas service on 18 January 1944 from the New York Port of Embarkation and arrived in the United Kingdom on 26 January 1944. During this period, it conducted amphibious training and rehearsals for its role in Operation Overlord.

Normandy Campaign

Utah Beach (6 June 1944)

On D-Day, 6 June 1944, the division landed on Utah Beach as part of the Allied invasion of Normandy. The assault was led by the 8th Infantry Regiment, followed by the 12th and 22nd Infantry Regiments. Due to strong currents and navigation errors, elements of the division landed approximately 2,000 yards south of their intended landing area. Brigadier General Theodore Roosevelt Jr., assistant division commander, landed with the first wave and made the decision to continue the assault from that location.

Despite the mislanding, the division encountered relatively lighter resistance compared to Omaha Beach. By the end of the day, it had successfully secured the beachhead and began advancing inland, linking up with airborne elements of the 82nd Airborne Division and 101st Airborne Division.

Cotentin Peninsula and Cherbourg

Following the landings, the division advanced across the Cotentin Peninsula, relieving airborne units and securing key terrain, including the area around Sainte-Mère-Église. The division played a major role in the capture of Cherbourg, a critical deep-water port for Allied logistics. The city fell on 25 June 1944 after heavy fighting.

Breakout from Normandy and advance across France

After the successful breakout from Normandy, the division advanced rapidly across France as German resistance weakened. Elements of the 12th Infantry Regiment later entered Paris in coordination with French forces during the liberation of the city in August 1944.

Siegfried Line and Hürtgen Forest

In September 1944, the division was among the first U.S. units to penetrate the Siegfried Line (Westwall), marking the transition from rapid advance to sustained combat against fortified German defenses. In November 1944, the division entered the Battle of Hürtgen Forest, one of the longest and most difficult battles fought by U.S. forces in Europe. Dense forest, rugged terrain, and determined German resistance resulted in heavy casualties and limited progress.

Ardennes Offensive

During the Battle of the Bulge in December 1944, the division was forced to withdraw from forward positions but established defensive lines that contributed to halting the German advance.

Final operations in Germany

In early 1945, the division resumed offensive operations, advancing into Germany as part of the broader Allied advance. It crossed the Rhine River and continued operations into central Germany. The division captured key objectives, including Würzburg, and continued advancing through southern Germany. By the end of the war in Europe on 8 May 1945, the division had advanced deep into Germany and was assigned occupation duties.

Operational significance

The combat record of the 4th Infantry Division reflects its role as a key assault and maneuver formation in the European Theater:

• Amphibious assault: Utah Beach (D-Day)
• Airborne link-up and expansion: Cotentin Peninsula
• Strategic objective: Capture of Cherbourg
• Breakout and pursuit: France
• Transition to fortified warfare: Siegfried Line
• Attritional combat: Hürtgen Forest
• Defensive operations: Ardennes Offensive
• Final advance: Germany, 1945

The division’s successful landing at Utah Beach secured the western flank of the Normandy invasion and enabled the rapid capture of Cherbourg, a vital logistical objective for sustaining Allied operations in France.
