 Dinter returned to Germany in 1914 and was obliged to remain there until after the end of the war.South Africa had been given a mandate to administer the former Deutsch-Südwest-Afrika and Dinter applied to the authorities to be reinstated as the regional botanist.To this end he returned to Okahandja in 1922 and helped with the planning of Ernst Julius Rusch's succulent garden on the farm Lichtenstein.
