Following the defeat, the Chief of the German General Staff, Field Marshal Paul von Hindenburg, ordered the "Oberste Heeresleitung" ("OHL", Supreme Army Command) to conduct a court of enquiry into the defensive collapse of the Arras sector. The court concluded that the 6th Army headquarters had disregarded frontline commander reports, noting a possible imminent attack and as a result, reserve units were kept too far back to execute a timely and effective counterattack. The court concluded that 6th Army commander General Ludwig von Falkenhausen failed to apply an elastic defence properly as espoused by German defensive doctrine of the time. Instead, the defensive system was a series of unmoving strong points and static lines of resistance, which the Allied artillery isolated and destroyed. Hindenburg removed Falkenhausen from his command and transferred him to Belgium where he served the remainder of the war as Governor General.
