Danzig and, to a lesser extent, Lübeck forces carried the main burden, supported by the cities of Hamburg and
Bremen. The city of
Cologne opposed the war and was temporarily excluded from the Hansa for this. As the
Burgundian duke
Charles the Bold cancelled his commitment to open his harbours, the Hanseatic privateers had to wait for departure until spring 1470. The rule of the English king, on the other hand, was weakened by the dynastic
Wars of the Roses and in September Edward IV even had to flee to the Burgundian
County of Flanders. Duke Charles backed Edward's return to England and now opened his harbours providing the Hansa forces to capture several vessels of the king's enemies. Upon the restoration of the English king, Charles again withdrew his support immediately. From 1472 onwards, the Hansa forces were able to operate in the English Channel up to
Ushant island with larger formations, led by Lübeck and Hamburg squadrons, and their advance even called up a
French fleet. The war was fought mainly by the use of the naval strategy of
commerce raiding. One of the most successful
man of war ships was the
Peter von Danzig under
Paul Beneke, which from 1473 raided the English coast and did not spare neutral ships nor vessels flying Burgundian flags. The war concluded with the
Treaty of Utrecht in 1474 which confirmed the Hansa privileges and granted the League ownership of the London Steelyard, as well as the trading bases in
Boston and
Lynn. It virtually halted English trade with Germany and the Baltic region. ==References==
