The area around Kalvslund and Brænøre was the last to be determined, since the border at Kalvslund would lead to Kalvslund’s peasant farmers having land on both sides of the border. This in turn would lead to them having to undergo border control every time they had to attend to their fields. It would also mean that a stretch of road between Ribe and Kolding would belong to Germany, which was impractical.
Kalvslund’s inhabitants wrote to the king, Christian IX, and asked that they be allowed to belong to Denmark. He intervened, and a solution was found whereby the border was moved approximately 200 m to the east. In return, Denmark had to give up an area near Brænøre.
The Customs Border Corps kept a criminal register of the border gendarmes’ transgressions, which for the most part consisted of being drunk or sleeping while on duty. In 1868, four gendarmes from Kalvslund were either arrested or reprimanded for having visited a dance hall without permission.
