In March 1918, the British and French Armies, under separate commands, opposed the furious attacks of numerically superior and more powerfully equipped enemy forces, grouped under the command of a single chief: Ludendorff.
THE GERMAN OFFENSIVE OF MARCH 21.
The Opposing Forces—Their Material and Moral Strength.
Towards the end of 1917, the abandonment of the Allies, by Russia, was consummated by the Russo-German Armistice of December 20, followed by the Peace of Brest-Litowsk, of February 9, 1918. As early as November 1917, Germany began to transfer her legions from the eastern to the western front. Arriving, via Belgium, in ever-increasing numbers, sixty-four new divisions were thus added to her Western Armies, already one hundred and forty-one divisions strong, giving a total strength of 205 German divisions against the Allies' 177 divisions.
The material resources, accumulated on the Russian front, were likewise transferred to the western front. The enemy's artillery was reinforced all along the line, the number of heavy batteries being doubled in many of the sectors.
