Second Battle of the Marne

The Second Battle of the Marne (French: Seconde Bataille de la Marne; 15 – 18 July 1918) was the last major German offensive on the Western Front during the First World War. The attack failed when an Allied counterattack, led by French forces and supported by several hundred Renault FT tanks, overwhelmed the Germans on their right flank, inflicting severe casualties.
