In October 1310 Grand arrived in the monastery in Hude, which belonged in religious respect to his new diocese, but as to the secular reign it was part of the County of Oldenburg. From there monks and representatives of the city of Bremen accompanied him into the Prince-Archbishopric of Bremen. The federation welcomed him warmly and accepted Grand as Prince-Archbishop. The federation and Grand made "Isern Hinnerk" abandon the castle in Vörde, with "Isern Hinnerk" entrenching in his own castle near Beckdorf.
