 The German victory at Lenzen was total, resulting in the suppression of effective Slavic resistance to German rule along the Elbe for the rest of Henry's reign.In the winter of 928, Henry I marched against the Slavic Hevelli tribes, intent on seizing their capital of Brandenburg, located along the Havel.The Hevelli were allied to the Bohemians, who in turn had permitted military access through their territory for the Magyars when they launched failed raids on the German duchies of Thuringia and Saxony in 924.
