This battle involved an offensive launched by the Germans, using troops released from fighting in the East, following the Russian Revolution. The idea was simply, to crush the allies before the arrival of the Americans. The action started in the Somme moving up to the Ypres sector. The final breakout utilised the same ideas as in 1917, but the Germans lacked the strength they had then and the breakout was achieved in two stages. By the day of the Armistice the British Army were 51 miles from the Salient.
