The Battle of the Marne was a significant conflict during World War I, fought from September 6 to September 12, 1914. It marked the end of the German advance into France and the beginning of trench warfare on the Western Front. The battle involved the forces of the Allies, primarily France and Britain, against the German Empire. The battle is notable for the successful counteroffensive launched by the Allies, which halted the German advance towards Paris. This victory prevented the Germans from achieving a quick victory in the war and set the stage for a prolonged conflict that would last for several years.
