Elsewhere French and then American forces pushed hard in the Meuse-Argonne Offensive, and gradually the German Army on the Western Front collapsed. The Kaiser abdicated in October 1918 and the new government of Germany decided to sue for peace. The last great British battle of the war was on 4th November 1918 along the Sambre Canal, a day when WW1 war poet Wilfred Owen was killed. The final shots were in the streets and suburbs of the city of Mons on 11th November 1918; a place where for the British, the war had begun in August 1914. As the war came to an end it had cost Britain and the Commonwealth more than a million war dead.
