Within the occupied Prince-Archbishopric the Leaguist occupants carried out the restitution. In Stade, "Tilly's" headquarters, all churches, except of St. Nicholas, were handed over to foreign Catholic clerics. But the burghers didn't attend Catholic services. So in March 1630 "Tilly" expelled all Lutheran clergy, except the one of St. Nicholas. "Tilly" levied high war contributions from "Stade's" burghers (e.g. 22,533 rixdollars in 1628 alone) and offered in 1630 to relieve every burgher, who would attend Catholic services, without success. In July 1630 "Tilly" left to head for the Duchy of Pomerania, where King Gustavus II Adolphus of Sweden had landed with his troops, opening a new front in the Thirty Years' War. He had been won by French diplomacy to join a new anti-imperial coalition, soon joined by the Netherlands.
