Battle of Saint-Mihiel

Contents

Battle of Saint-Mihiel. The Battle of Saint-Mihiel was a significant military operation launched by the American Expeditionary Forces under the command of John J. Pershing, in conjunction with the French Army led by Georges Clemenceau and Ferdinand Foch, against the German Army under Kaiser Wilhelm II and Erich Ludendorff, as part of the broader Western Front campaign during World War I. This battle was a crucial test of the American Expeditionary Forces' ability to operate independently and marked a significant turning point in the war, as it coincided with the Battle of the Argonne Forest and the Meuse-Argonne Offensive, involving forces such as the United States Army Air Service and the French Air Force. The operation also involved coordination with other Allies of World War I, including the British Expeditionary Force under Field Marshal Douglas Haig and the Canadian Expeditionary Force under Arthur Currie.

Background

The Battle of Saint-Mihiel was set against the backdrop of the Hundred Days Offensive, a series of attacks by the Allies of World War I that began with the Battle of Amiens and would eventually lead to the Armistice of Compiègne. The strategic Saint-Mihiel salient, held by the German Army since 1914, posed a significant threat to the Allies of World War I' supply lines and communication networks, including those of the French Third Republic and the United Kingdom of Great Britain and Ireland. The American Expeditionary Forces, having gained experience in earlier battles such as the Battle of Belleau Wood and the Battle of Château-Thierry, were now ready to undertake a major operation under their own command, with support from French Army units like the Groupe d'armées de l'Est and Groupe d'armées du Centre. This operation would also involve coordination with other Allied forces, including the Belgian Army under Albert I of Belgium and the Portuguese Expeditionary Corps.

The American Expeditionary Forces assembled a large force for the operation, including the I Corps under Hunter Liggett, the IV Corps under George H. Cameron, and the V Corps under George B. Dyer, supported by French Army divisions such as the 37th Infantry Division and 2nd Colonial Division. The German Army defenders, primarily from the German Fifth Army under Georg von der Marwitz and the German Seventh Army under Max von Boehn, were well-entrenched but had been weakened by the ongoing Hundred Days Offensive and the Second Battle of the Marne, which involved forces like the United States Marine Corps and the Australian Corps. The American Expeditionary Forces also enjoyed significant air support from the United States Army Air Service, which worked closely with the French Air Force and the Royal Air Force to provide reconnaissance and combat missions, including those flown by Eddie Rickenbacker and other Lafayette Escadrille pilots.

The Battle of Saint-Mihiel began on September 12, 1918, with a massive artillery barrage by the American Expeditionary Forces and French Army against the German Army positions, followed by an infantry advance supported by tanks from the United States Tank Corps and French Renault FTs. The American Expeditionary Forces made rapid gains, pushing deep into the Saint-Mihiel salient and threatening to encircle the German Army defenders, who were also facing pressure from the Battle of the Argonne Forest and other Allied operations, including those led by Philippe Pétain and Ferdinand Foch. By September 15, the American Expeditionary Forces had achieved their objectives, capturing key locations such as Saint-Mihiel and Thiaucourt-Regniéville, and forcing the German Army to withdraw from the salient, marking a significant victory for the Allies of World War I and a major milestone in the Meuse-Argonne Offensive, which involved forces like the United States Army and the Canadian Corps.

The success of the Battle of Saint-Mihiel marked a significant turning point in the war, as it demonstrated the ability of the American Expeditionary Forces to operate independently and effectively, and it set the stage for the larger Meuse-Argonne Offensive, which would eventually involve over a million American Expeditionary Forces soldiers, including those from the United States Army and the United States Marine Corps. The battle also marked a significant shift in the balance of power on the Western Front, as the Allies of World War I gained momentum and the German Army began to retreat, leading to the eventual Armistice of Compiègne and the end of World War I, which would be negotiated by leaders like Woodrow Wilson, David Lloyd George, and Georges Clemenceau at the Paris Peace Conference. The Battle of Saint-Mihiel also had significant implications for the Treaty of Versailles and the post-war settlement, as it contributed to the defeat of the German Empire and the Austro-Hungarian Empire, leading to the rise of new powers like the United States and the Soviet Union.

The Battle of Saint-Mihiel is remembered as a significant milestone in the history of the American Expeditionary Forces and the United States Army, marking a major turning point in the war and demonstrating the ability of American forces to operate effectively in a major military campaign, alongside other Allies of World War I like the French Army and the British Army. The battle is also commemorated in numerous memorials and museums, including the American Battle Monuments Commission and the National World War I Museum and Memorial, which honor the sacrifices of soldiers like Alvin York and Eddie Rickenbacker, and provide a testament to the enduring legacy of the Battle of Saint-Mihiel and its significance in the history of World War I and the Western Front. The battle's legacy continues to be studied by military historians and strategists, including those at the United States Army Command and General Staff College and the French Military Academy, who seek to understand the lessons of the past and apply them to modern military operations, involving forces like the North Atlantic Treaty Organization and the European Union.
