Hundred Days Offensive in the context of "Battle of Cambrai (1917)"

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.

Ferdinand Foch (/fɒʃ/ FOSH, French: [fɛʁdinɑ̃ fɔʃ]; 2 October 1851 – 20 March 1929) was a French general, Marshal of France and a member of the Académie Française and Académie des Sciences. He distinguished himself as Supreme Allied Commander on the Western Front during the First World War in 1918.

A commander during the First Marne, Flanders and Artois campaigns of 1914–1916, Foch became Supreme Allied Commander in late March 1918 in the face of the all-out German spring offensive. He successfully coordinated the French, British and American efforts, deftly handling his strategic reserves. He stopped the German offensive and launched a war-winning counterattack. In November 1918, Marshal Foch accepted the German cessation of hostilities and was present at the Armistice of 11 November 1918.

Amiens (English: /æˈmjæ̃/ or /ˈæmiənz/ AM-ee-ənz; French: [amjɛ̃] ; Picard: Anmien, Anmiens or Anmyin) is a city and commune in northern France, located 120 km (75 mi) north of Paris and 100 km (62 mi) south-west of Lille. It is the capital of the Somme department in the region of Hauts-de-France and had a population of 135,429, as of 2021. A central landmark of the city is Amiens Cathedral, the largest Gothic cathedral in France. Amiens also has one of the largest university hospitals in France, with a capacity of 1,200 beds. The author Jules Verne lived in Amiens from 1871 until his death in 1905, and served on the city council for 15 years. Amiens is the birthplace of French president Emmanuel Macron.

The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath, the city was rebuilt according to Pierre Dufau's plans with wider streets to ease traffic congestion. These newer structures were primarily built of brick, concrete and white stone with slate roofs. The architect Auguste Perret designed the Gare d'Amiens train station and nearby Tour Perret.

Field Marshal Douglas Haig, 1st Earl Haig, KT, GCB, OM, GCVO, KCIE (/heɪɡ/; 19 June 1861 – 29 January 1928) was a senior officer of the British Army. During the First World War he commanded the British Expeditionary Force (BEF) on the Western Front from late 1915 until the end of the war.

Haig's military career included service in the War Office, where he was instrumental in the creation of the Territorial Force in 1908. In January 1917 he was promoted to the rank of field marshal, subsequently leading the BEF during the final Hundred Days Offensive. This campaign, in combination with the Kiel mutiny, the Wilhelmshaven mutiny, the proclamation of a republic on 9 November 1918 and revolution across Germany, led to the armistice of 11 November 1918. It is considered by some historians to be one of the greatest victories ever achieved by a British-led army.
