Operation Michael, the German offensive of March-July 1918, represented Germany's final attempt to achieve a decisive victory on the Western Front before American reinforcements tipped the balance decisively against Germany. Initiated by General Ludendorff in the spring of 1918, the operation began with a massive artillery bombardment and an assault by nearly 4 million soldiers along the Western Front. For the first time in three years, German forces achieved a breakthrough, advancing up to 65 kilometers in some sectors. Yet despite this initial success, the offensive ultimately failed, exhausting Germany's remaining military resources and ensuring final defeat.

Strategic Necessity and German Planning

By 1918, Germany's strategic situation had become dire. The Russian collapse and the subsequent Treaty of Brest-Litovsk freed German forces from the Eastern Front, allowing Germany to concentrate forces in the west. However, American forces were arriving in France in increasing numbers—over 2 million American soldiers would eventually serve in France. Ludendorff recognized that Germany had perhaps six months before American numbers would make a German victory impossible. He therefore committed Germany to a massive offensive designed to break the British and French lines and force the Allies to negotiate peace.

The German offensive began on March 21, 1918, with a bombardment of unprecedented intensity. Over 1 million shells fell on British positions in a matter of hours. The German infantry assault that followed was based on new 'stormtrooper' tactics developed by German junior officers—infiltration of weak points in the enemy line followed by exploitation toward deep objectives rather than advancing rigidly along front lines. The British Fifth Army under General Edmund Allenby, weakened by earlier attrition, broke under the assault. The German advance proceeded rapidly, capturing tens of thousands of prisoners and hundreds of artillery pieces.

Initial Success and Mounting Problems

For the first time since the opening of the Western Front in 1914, German forces achieved meaningful territorial advances. The breakthrough seemed to promise final victory. However, the German successes created their own problems. Supply lines stretched to the breaking point. Infantry advancing across devastated terrain captured more ground than logistical systems could support. Reinforcements could not keep pace with the advance. Meanwhile, the Allies, initially panicked, rallied under the unified command of French General Ferdinand Foch. Fresh reserves were committed to counter-attacks. American forces, now arriving in increasing numbers, provided additional manpower.

The German momentum, built on momentum and initial shock, gradually dissipated. Counter-attacks by French and British forces, and the growing presence of American troops, combined to halt the German advance. Ludendorff, recognizing the failure of his grand strategy, attempted further offensives, but each successive assault produced diminishing returns. By July, the window for German victory had closed. The Allies launched their own offensives in August and September, pushing German forces backward. Germany, having committed its last reserves to Operation Michael and having achieved nothing but tactical gains, possessed no resources for final defense. The German collapse came in November 1918, less than eight months after Operation Michael began. Ludendorff's last gamble had failed, and Germany faced defeat and revolution.
