79th Division (United States)

79th Division (United States)

The 79th Division (United States) is a formation of the United States Army with origins in World War I that later served in various training and reserve roles through World War II and the Cold War. Raised under the Selective Service Act of 1917 and organized at Camp Meade, the division deployed to the Western Front during the First World War and later underwent multiple reorganizations linked to the National Army (United States), the Organized Reserve Corps, and the United States Army Reserve. The unit's service intersects with campaigns such as the Meuse-Argonne Offensive and figures including commanders from the United States Army Chief of Staff lineage.

History

The division was constituted in the National Army (United States) following United States entry into the First World War under the authority of the Selective Service Act of 1917 and organized at Camp Meade, Maryland. Trained by cadres drawn from Regular Army units including elements associated with the Fort Meade establishment, it deployed to France as part of the American Expeditionary Forces. In the spring of 1918 the division was assigned to operations in the Lorraine region and later participated in the Meuse-Argonne Offensive, operating in coordination with formations of the British Expeditionary Force and the French Army. After demobilization at Camp Dix following the Armistice of 11 November 1918, the division was reconstituted in the Organized Reserve Corps between the wars and stationed in the northeastern United States, linking its heritage to state institutions and Reserve Officers' Training Corps units. During the Second World War the division was reactivated for training and replacement missions under commands associated with the Army Ground Forces and later redesignated in the postwar era as part of the evolving United States Army Reserve structure.

Organization and Structure

Originally organized as an infantry division, the 79th Division's World War I table of organization included infantry brigades, field artillery brigades, engineer units, and support elements as prescribed by Army organization policy and doctrines promulgated by the War Department. Subordinate units historically included infantry regiments and artillery regiments formed under the numbering conventions used by the Center of Military History and coordinated with corps-level formations such as I Corps and III Corps. Between wars, its structure adapted to the Organized Reserve Corps model with headquarters in locations tied to Pennsylvania, New Jersey, and surrounding states, incorporating personnel from Citizens' Military Training Camps and officers from Reserve Officers' Training Corps programs at institutions like Penn State University, Rutgers University, and Princeton University. During World War II and the Cold War the division's organization was altered under Triangular Division reforms and later under postwar reserve command reorganizations directed by the National Defense Act Amendments and policy from the Office of the Secretary of Defense.

Combat Operations

In France during the First World War the division saw action in sectors of the Lorraine defenses and was committed to the Meuse-Argonne Offensive where it faced German formations including units of the German Empire. Its operations involved coordinated assaults supported by units from the American Expeditionary Forces artillery assets and engineer detachments, and it worked in operational conjunctions with elements of the Fourth Army and allied French corps during combined operations. The division's engagements occurred against the backdrop of strategic decisions by leaders in the American Expeditionary Forces such as John J. Pershing and were influenced by logistics chains routed through ports like Le Havre and railheads connected to the Ports of Embarkation. While World War II saw some divisions of the same numeric series deployed to the European and Pacific Theaters under commands like U.S. Army Europe and United States Army Pacific, this division's wartime role shifted toward training, replacement, and administrative missions supervised by Army Ground Forces and Replacement and School Command organizations rather than sustained front-line divisional combat as a unit.

Postwar Service and Reorganizations

Following the Second World War, the division was inactivated and its lineage transferred into the Organized Reserve Corps, later redesignated within the United States Army Reserve system. Cold War reorganizations under the Pentomic Division experiments and later the Reorganization Objective Army Divisions impacted reserve formations, prompting realignments of the 79th's brigades, battalions, and support units. The division headquarters and subordinate elements were reassigned across installations including Fort Dix, Fort Devens, and regional reserve centers, integrating with training programs overseen by the TRADOC and mobilization plans coordinated with United States Northern Command and U.S. Army Reserve Command. During the late 20th and early 21st centuries, elements bearing the division's lineage contributed personnel to operations such as Operation Desert Shield, Operation Iraqi Freedom, and Operation Enduring Freedom through individual mobilization augmenting active duty formations.

Honors and Legacy

The division earned campaign credit for Meuse-Argonne Offensive and related World War I operations and its soldiers received individual decorations tied to actions in France, recognized by documents of the United States Army Center of Military History. Its shoulder sleeve insignia and divisional insignia entered heraldry records maintained by the Institute of Heraldry (United States). The unit's legacy endures in Reserve training traditions, commemorations at memorials such as Meuse-Argonne American Cemetery and Memorial, and institutional histories preserved at repositories including the National Archives and Records Administration and the United States Army Heritage and Education Center. Associations of veterans and reenactor groups maintain lineage awareness alongside academic treatments found in works by historians connected to United States Army Center of Military History and university military history programs.
