The Australians then achieved a series of victories against the Germans at Chuignes, Mont St Quentin, Peronne and Hargicourt. Monash had 208,000 men under his command, including 50,000 inexperienced Americans. Monash planned the attack on the German defences in the Battle of the Hindenburg Line between 16 September and 5 October 1918. The Allies eventually breached the Hindenburg Line by 5 October, and the war was essentially over. On 5 October, Prinz Max von Baden, on behalf of the German Government, asked for an immediate armistice.
