Ludendorff selected as his battlefield an eighty-kilometer front from La Fère to Arras defended by the British army, regarded as less skilled than its French ally.
He refused to set final territorial objectives. This was a gross error, for the British army was highly vulnerable at the rail hubs of Amiens and Hazebrouck and capturing these logistical choke points could have pushed it from the continent. Instead, Ludendorff chose his attack front with two other aims in mind. First, he hoped to punch through at the boundary between the British and French armies here and then turn north to eliminate the British line. Second, tactical and psychological calculations were paramount.
The defenders were weak here, raising the likelihood of a breakthrough. Once dislodged, the enemy’s unwieldy command system and troops schooled only in trench combat were expected to collapse quickly under the pressure of mobile war. There were serious command errors. Ludendorff squandered his best chance at victory by missing British logistical vulnerabilities, and he lost a grip on the operations, repeatedly reinforcing mere tactical successes.
