The Spring Offensive, also known as Kaiserschlacht (the "battle for the Emperor"), was the last major offensive of the German military forces on the western front. The Germanic general staff rested in it all the hopes of victory, before the American forces arrived in large numbers, making the numerical superiority of the Allies overwhelming. The desperate German attacks, even arriving at the gates of Paris and endangering the Anglo-French positions, ended in nothing with heavy losses that could no longer be settled. Germany was close to defeat.
