During this time, irregular support had been provided by the Protestant (and non-Protestant) powers of Europe (Kingdom of England, the Dutch Republic) for the Protestant cause in Germany. Both Sweden and Denmark sought to receive aid in order to bring a powerful nation into the German conflict proper, but the terms on which Gustavus proposed had some very definite clauses, and as Christian of Denmark effectively underbid him, support was provided to him. The sum of the Danes' effort was although they achieved some initial inroads into Roman Catholic territory, the Catholic League, under the able General Albrecht von Wallenstein (who is reported on one occasion to have told Ferdinand that Gustavus was worse than "the Turk") defeated them at the Battle of Lutter. This resulted in the treaty of Lubeck and the expulsion of any major Protestant combatant from the German theatre. All of Germany was effectively in the hands of the Holy Roman Emperor.
