Beginning on 21 March 1918 the Germans launched a series of five offensives known as the 1918 Spring Offensive, or Kaiserschlacht ("Kaiser’s Battle"). The first two offensives, Michael and Georgette, were aimed at the British armies. The objectives were to separate the British and French forces, to push the British armies back to the English Channel and to cut the rail line through Hazebrouck, the main supply line for the British force. Although successful in pushing the British back, Michael was unsuccessful in separating the French and British armies while Georgette was checked north of Hazebrouck and failed to cut the British supply line.
