独仏休戦協定
Immerhof saw little action during 1940, at most seeing harassing fire, resulting in the death of corporal Andé Rabu on 14 June.. German forces bypassed the area in the days leading up to the Second Armistice at Compiègne. The Immerhof garrison, under the command of Captain Réquiston, surrendered to the German occupiers on 30 June 1940.
