They had to pay an indemnity in silver, estimated at ten times the annual income of the King of England, in four annual installments.[86] To meet these payments, the Knights borrowed heavily, confiscated gold and silver from churches and increased taxes. Two major Prussian cities, Danzig (Gdańsk) and Thorn (Toruń), revolted against the tax increases.[88] The defeat at Grunwald left the Teutonic Knights with few forces to defend their remaining territories. Since Samogitia became officially christened, as both Poland and Lithuania were for a long time, the Knights had difficulties recruiting new volunteer crusaders.[89] The Grand Masters then needed to rely on mercenary troops, which proved an expensive drain on their already depleted budget.
