American Expeditionary Forces in the context of "General of the Armies"

The Meuse–Argonne offensive (also known as the Meuse River–Argonne Forest offensive, the Battles of the Meuse–Argonne, and the Meuse–Argonne campaign) was a major part of the final Allied offensive of World War I that stretched along the entire Western Front. It was fought from September 26, 1918, until the Armistice of November 11, 1918, a total of 47 days. The Meuse–Argonne offensive was the largest in United States military history, involving 1.2 million American soldiers, sailors and marines, along with 800,000 French and 850 Siamese personnel. It is also the deadliest campaign in the history of the United States Army, resulting in over 350,000 casualties, including 28,000 German lives, 26,277 American lives and an unknown number of French lives. American losses were worsened by the inexperience of many of the troops, the tactics used during the early phases of the operation, and the widespread onset of the global influenza outbreak called the "Spanish flu."

The offensive was the principal engagement of the American Expeditionary Forces (AEF) in World War I. It was one of a series of Allied attacks, known as the Hundred Days Offensive, which brought the war to an end. It was the largest and bloodiest operation of the entire war for the AEF even though, given the scale of other battles on the Western Front, its size was limited and the operation itself secondary, being far from the main offensive axis.

Wendell Lewis Willkie (born Lewis Wendell Willkie; February 18, 1892 – October 8, 1944) was an American lawyer, corporate executive and the 1940 Republican nominee for president of the United States. Willkie appealed to many convention delegates as the Republican field's only interventionist: although the U.S. remained neutral prior to Pearl Harbor, he favored greater U.S. involvement in World War II to support Britain and other Allies. His Democratic opponent, incumbent President Franklin D. Roosevelt, who had made campaign pledges against U.S. involvement in World War II, won the 1940 election with about 55% of the popular vote and took the electoral college vote by a wide margin.

Willkie was born in Elwood, Indiana, in 1892; both his parents were lawyers, and he also became one. He served in World War I but was not sent to France until the final days of the war, and saw no action. Willkie settled in Akron, Ohio, where he was initially employed by Firestone, but left for a law firm, becoming one of the leaders of the Akron Bar Association. Much of his work was representing electric utilities, and in 1929 Willkie accepted a job in New York City as counsel for Commonwealth & Southern Corporation (C&S), a utility holding company. He was rapidly promoted, and became corporate president in 1933. Roosevelt was sworn in as U.S. president soon after Willkie became head of C&S, and announced plans for a Tennessee Valley Authority (TVA) that would supply power in competition with C&S. Between 1933 and 1939, Willkie fought against the TVA before Congress, in the courts, and before the public. He was ultimately unsuccessful, but sold C&S's property for a good price, and gained public esteem.

The United States became directly involved in World War I after declaring war on Germany on April 6, 1917. The declaration ended nearly three years of American neutrality in the war since the beginning, and the country's involvement in the conflict lasted for nineteen months before a ceasefire and armistice were declared on November 11, 1918. The U.S. played a major role in providing much needed supplies, raw material, and money to the United Kingdom, France, and the other Allied powers, even well before 1917.

After declaring war, the U.S. mobilized over 5 million military personnel. General John J. Pershing commanded the American Expeditionary Force (AEF) in France, in which over 2 million American soldiers served. American troops began to arrive in Europe by June 1917, first at a slow rate, but by the summer of 1918 the rate had skyrocketed to 10,000 soldiers arriving each day. Most of the ground fighting for the U.S. took place on the Western Front. At sea, the U.S. Navy would play a key role in the Allied convoy system and in the ongoing battle against German submarines. Over 116,000 American servicemen were lost in the war.

George Catlett Marshall Jr. (31 December 1880 – 16 October 1959) was an American army officer and statesman. He rose through the United States Army to become Chief of Staff of the U.S. Army under presidents Franklin D. Roosevelt and Harry S. Truman, then served as Secretary of State and Secretary of Defense under Truman. Winston Churchill lauded Marshall as the "organizer of victory" for his leadership of the Allied victory in World War II. During the subsequent year, he unsuccessfully tried to prevent the continuation of the Chinese Civil War. As Secretary of State, Marshall advocated for a U.S. economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of this work, he was awarded the Nobel Peace Prize in 1953, the only Army general ever to receive the honor.

Born in Uniontown, Pennsylvania, Marshall graduated from the Virginia Military Institute (VMI) in 1901. He received his commission as a second lieutenant of Infantry in February 1902 and immediately went to the Philippines. He served in the United States and overseas in positions of increasing rank, including platoon leader and company commander in the Philippines during the Philippine–American War. He was the top-ranked of the five Honor Graduates of his Infantry-Cavalry School Course in 1907 and graduated first in his 1908 Army Staff College class. In 1916 Marshall was assigned as aide-de-camp to J. Franklin Bell, the commander of the Western Department. After the nation entered the First World War in 1917, Marshall served with Bell, who commanded the Department of the East. He was assigned to the staff of the 1st Division; he assisted with the organization's mobilization and training in the United States, as well as planning of its combat operations in France. Subsequently assigned to the staff of the American Expeditionary Forces headquarters, he was a key planner of American operations, including the Meuse-Argonne Offensive.

The Bonus Army was a group of 43,000 demonstrators—17,000 veterans of U.S. involvement in World War I, their families, and affiliated groups—who gathered in Washington, D.C., in mid-1932 to demand early cash redemption of their service bonus certificates. Organizers called the demonstrators the Bonus Expeditionary Force (B.E.F.), to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers". The demonstrators were led by Walter W. Waters, a former sergeant. Many of the war veterans had been out of work during the beginning of the Great Depression. The World War Adjusted Compensation Act of 1924 had awarded all World War I veterans "bonuses" in the form of certificates they could not redeem until 1945. Each certificate, issued to a qualified veteran soldier, bore a face value equal to the soldier's promised payment with compound interest. The principal demand of the Bonus Army was the immediate cash payment of their certificates.

On July 28, 1932, U.S. Attorney General William D. Mitchell ordered the veterans removed from all government property. Washington police met with resistance, shot at the protestors, and two veterans were wounded and later died. President Herbert Hoover then ordered the U.S. Army to clear the marchers' campsite. Army Chief of Staff General Douglas MacArthur commanded a contingent of infantry and cavalry, supported by six tanks. The Bonus Army marchers with their wives and children were driven out, and their shelters and belongings burned.

General of the Armies John Joseph Pershing (September 13, 1860 – July 15, 1948), nicknamed "Black Jack", was an American army general, educator, and founder of the Pershing Rifles. He served as the commander of the American Expeditionary Forces (AEF) during World War I from 1917 to 1920. In addition to leading the AEF to victory in World War I, Pershing served as a mentor to many in the generation of generals who led the United States Army during World War II, including George C. Marshall, Dwight D. Eisenhower, Omar Bradley, Lesley J. McNair, George S. Patton, and Douglas MacArthur.

During his command in World War I, Pershing resisted British and French demands that American forces be integrated with their armies, essentially as replacement units, and insisted that the AEF would operate as a single unit under his command, although some American units fought under British and Australian command, notably in the Battle of Hamel and the breaching of the Hindenburg Line at St Quentin Canal, precipitating the final German collapse. Pershing also allowed (at that time segregated) American all-Black units to be integrated with the French Army.

The Third Battle of the Aisne (French: 3 Bataille de l'Aisne) was part of the German spring offensive during World War I that focused on capturing the Chemin des Dames Ridge before the American Expeditionary Forces arrived completely in France. It was one of a series of offensives, known as the Kaiserschlacht, launched by the Germans in the spring and summer of 1918.

The Battle of Château-Thierry was fought from late May to early June 1918 and was one of the first actions of the American Expeditionary Forces (AEF) under General John J. Pershing. It was a battle in World War I as part of the Second Battle of the Marne, initially prompted by a German Spring Offensive. German and local actions at Château-Thierry recommenced on May 31 to July 22, 1918, against the AEF, an American Expeditionary Force, consisting of troops from both the United States Army and Marine Corps units. These units from the 2nd US Division were the newest troops on the front in France and just barely out of training.

The AEF counter-offensive combat action at Château-Thierry was relatively brief starting on July 1, 1918 and lasting for less than a week and was part of the allied effort to push back the recent German advance. American forces had linked up with their French allies at the Marne River on June 3, 1918 and had forced the Germans back across the river. This set the stage for the action at Château-Thierry and at the Battle of Belleau Wood. However, the later action raged for another three weeks.
