Army led formation of the U. S. Armed Forces on the Western Front of World War I

The American Expeditionary Forces (AEF) was a formation of the United States Armed Forces on the Western Front during World War I, comprised mostly of units from the U. S. Army. The AEF was established on July 5, 1917, in France under the command of then Major General John J. Pershing. It fought alongside French Army, British Army, Canadian Army, British Indian Army, New Zealand Army and Australian Army units against the Imperial German Army. A small number of AEF troops also fought alongside Italian Army units in 1918 against the Austro Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château Thierry and Battle of Belleau Wood) in the summer of 1918, and fought its major actions in the Battle of Saint Mihiel and the Meuse Argonne Offensive in the latter part of 1918.

President Woodrow Wilson initially planned to give command of the AEF to Gen. Frederick Funston, but after Funston's sudden death, Wilson appointed Major General John J. Pershing in May 1917, and Pershing remained in command for the rest of the war. Pershing insisted that American soldiers be well trained before going to Europe. As a result, few troops arrived before January 1918. In addition, Pershing insisted that the American force would not be used merely to fill gaps in the French and British armies, and he resisted European efforts to have U. S. troops deployed as individual replacements in depleted Allied units. This approach was not always well received by the western Allied leaders who distrusted the potential of an army lacking experience in large scale warfare. In addition, the British government tried to use its spare shipping as leverage to bring US soldiers under British operational control. By June 1917, only 14,000 American soldiers had arrived in France, and the AEF had only a minor participation at the front up to late October 1917, but by May 1918 over one million American troops were stationed in France, though only half of them made it to the front lines. Since the transport ships needed to bring American troops to Europe were scarce at the beginning, the U. S. Army pressed into service passenger liners, seized German ships, and borrowed Allied ships to transport American soldiers from the Hoboken Port of Embarkation with facilities in New York City and New Jersey, and the Newport News Port of Embarkation in Virginia. The mobilization effort taxed the American military to the limit and required new organizational strategies and command structures to transport great numbers of troops and supplies quickly and efficiently. The French harbors of Bordeaux, La Pallice, Saint Nazaire, and Brest became the entry points into the French railway system that brought the American troops and their supplies to the Western Front. American engineers in France also built 82 new ship berths, nearly 1000 mile (1609 km) of additional standard gauge tracks, and over 100000 mile (160934 km) of telephone and telegraph lines. by which time troop numbers justified it. Initially II Corps consisted of the 27th, 30th, 33rd, 78th and 80th Divisions. In June 1918, many component infantry units from II Corps – commanded by Maj. Gen. George W. Read – were attached to veteran British Army or Australian Army units. This served two purposes: familiarizing the Americans with actual battlefield conditions in France, and temporarily reinforcing the British Empire units that were often severely depleted in numbers, after more than three years of fighting. In fact, the first major operation in World War I to involve US troops concerned individual infantry platoons of the 33rd Division, which were attached to battalions of the Australian Corps for the Battle of Hamel on the 4th of July. Their involvement was voluntary and occurred despite last minute orders from AEF headquarters, that its troops should not take part in offensive operations led by non US generals. Thus Hamel was historically significant as the first major offensive operation during the war to involve US infantry and the first occasion on which US units had fought alongside British Empire forces. The AEF used French and British equipment. Particularly appreciated were the French canon de 75 modèle 1897, the canon de 155 C modèle 1917 Schneider, and the canon de 155mm GPF. American aviation units received the SPAD XIII and Nieuport 28 fighters, and the U. S. Army tank corps used French Renault FT light tanks. Pershing established facilities in France to train new arrivals with their new weapons. By the end of 1917, four divisions were deployed in a large training area near Verdun: the 1st Division, a regular army formation; the 26th Division, a National Guard division; the 2nd Division, a combination of regular troops and U. S. Marines; and the 42nd "Rainbow" Division, a National Guard division made up of soldiers from nearly every state in the United States. The fifth division, the 41st Division, was converted into a depot division near Tours.

Logistic operations were under the direction of Chicago banker Charles G. Dawes, with the rank first of colonel and then brigadier general. Dawes reported directly to Gen. Pershing. Dawes recommended in May 1918 that the allies set up a joint logistics planning board, which was approved by the Allies in the form of the Military Board of Allied Supply (MBAS), which coordinated logistics and transportation on the Western and Italian fronts. Supporting the two million soldiers across the Atlantic Ocean was a massive logistical enterprise. In order to be successful, the Americans needed to create a coherent support structure with very little institutional knowledge. The AEF developed support network appropriate for the huge size of the American force. It rested upon the Services of Supply in the rear areas, with ports, railroads, depots, schools, maintenance facilities, bakeries, clothing repair shops (termed salvage), replacement depots, ice plants, and a wide variety of other activities. The Services of Supply initiated support techniques that would last well into the Cold War including forward maintenance, field cooking, graves registration (mortuary affairs), host nation support, motor transport, and morale services. The work of the logisticians enabled the success of the AEF and contributed to the emergence of the American Army as a modern fighting force.

African Americans were drafted on the same basis as whites and made up 13 percent of the draftees. By the end of the war, over 350,000 African Americans had served in AEF units on the Western Front. However, they were assigned to segregated units commanded by white officers. One fifth of the black soldiers sent to France saw combat, compared to two thirds of the whites. They were three percent of AEF combat forces, and under two percent of battlefield fatalities. "The mass of the colored drafted men cannot be used for combatant troops", said a General Staff report in 1918, and it recommended that "these colored drafted men be organized in reserve labor battalions." They handled unskilled labor tasks as stevedores in the Atlantic ports and common laborers at the camps and in the Services of the Rear in France. The French, whose front line troops were resisting combat duties to the point of mutiny, requested and received control of several regiments of black combat troops. Kennedy reports "Units of the black 92nd Division particularly suffered from poor preparation and the breakdown in command control. As the only black combat division, the 92nd Division entered the line with unique liabilities. It had been deliberately dispersed throughout several camps during its stateside training; some of its artillery units were summoned to France before they had completed their courses of instruction, and were never fully equipped until after the Armistice; nearly all its senior white officers scorned the men under their command and repeatedly asked to be transferred. The black enlisted men were frequently diverted from their already attenuated training opportunities in France in the summer of 1918 and put to work as stevedores and common laborers." The 369th, 370th, 371st, and 372nd Infantry Regiments (nominally the 93d Division, but never consolidated as such) served with distinction under French command with French colonial units in front line combat. The French did not harbor the same levels of disdain based on skin color and for many Americans of African descent it was a liberating and refreshing experience. These African American soldiers wore American uniforms, some dating from the time of the Union Army, with French helmets and were armed with French Model 1907/15 Berthier rifle manufactured by Remington Arms, rather than the M1903 Springfield or M1917 Enfield rifles issued to most American soldiers. One of the most distinguished units was the 369th Infantry Regiment, known as the Harlem Hellfighters. The 369th was on the front lines for six months, longer than any other African American regiment in the war. One hundred seventy one members of the 369th were awarded the Legion of Merit. One member of the 369th, Sergeant Henry Johnson, was awarded the French Croix de guerre, and posthumously the Medal of Honor.

At the beginning, during the spring of 1918, the four battle ready U. S. divisions were deployed under French and British command to gain combat experience by defending relatively quiet sectors of their lines. After the first offensive action and American led AEF victory on 28 May 1918 at the Battle of Cantigny, by the U. S. 1st Division, and a similar local action by the 2nd Division at Belleau Wood beginning 6 June, both while assigned under French Corps command, Pershing worked towards the deployment of an independent US field Army. The rest followed at an accelerating pace during the spring and summer of 1918. By June Americans were arriving in theater at the rate of 10,000 a day; most of which entered training by British, Canadian and Australian battle experienced officers and senior non commissioned ranks. The training took a minimum of six weeks due to the inexperience of the servicemen. The first offensive action by AEF units serving under non American command was 1,000 men (four companies from the 33d Division), with the Australian Corps during the Battle of Hamel on 4 July 1918. (Corporal Thomas A. Pope was awarded the Medal of Honor for this battle.) This battle took place under the overall command of the Australian Corps commander, Lt. Gen. Sir John Monash. The Allied force in this battle combined artillery, armor, infantry, and air support (combined arms), which served as a blueprint for all subsequent Allied attacks, using "tanks". U. S. Army and Marine Corps troops played a key role in helping stop the German thrust towards Paris, during the Second Battle of the Marne in June 1918 (at the Battle of Château Thierry (1918) and the Battle of Belleau Wood). The first major and distinctly American offensive was the reduction of the Saint Mihiel salient during September 1918. During the Battle of Saint Mihiel, Pershing commanded the U. S. First Army, composed of seven divisions and more than 500,000 men, in the largest offensive operation ever undertaken by United States armed forces. This successful offensive was followed by the Meuse Argonne offensive, lasting from September 26 to November 11, 1918, during which Pershing commanded more than one million American and French combatants. In these two military operations, Allied forces recovered more than 200 sq mi (488 km2) of French territory from the German army. By the time the World War I Armistice had suspended all combat on November 11, 1918, the American Expeditionary Forces had evolved into a modern, combat tested army. These latter two were known as the American Expeditionary Force Siberia, and the American Expeditionary Force North Russia.

The AEF sustained about 320,000 casualties: 53,402 battle deaths, 63,114 noncombat deaths and 204,000 wounded. Relatively few men suffered actual injury from poison gas, although much larger numbers mistakenly thought that they had been exposed. Faculty included Walter M. Chandler, a Progressive Party member and, later, a Republican Party member of the U. S. House of Representatives from the State of New York. Botanist Edwin Blake Payson was also an instructor there.
