This presentation by Dr Bill Stewart, is about the German defensive doctrine in 1917-1918. This centrepiece of this doctrine was that of the counterattack allied with a flexible defence-in-depth to frustrate Allied attacks. They could deliver punishing counter blows that violently overthrew Allied advances.
This presentation examines four case studies of German multi-battalion counterattacks in 1917 and 1918 at Arras based on Canadian and German records. The presentation will explain why, despite favourable circumstances, these counterattack in 1918 failed unlike 1917.
