The Grebbe Line was the principal defensive position into Fortress Holland from the east. Following a preparatory bombardment, the outpost line was attacked at sunrise on 11 May and the defenders slowly fell back to the trenches on the hill. The front line proper was penetrated by the Germans on the afternoon of 12 May, setting the stage for the final assault the next day. . .
