With their usual astuteness they utilized wisely all periods of calm, and reckoned with the love of gain to help them in less peaceful moments. When the English made things uncomfortable for them at home, they revenged themselves upon them at Bruges or at Bergen, paralysing their commerce, and harassing their vessels, even forbidding them to enter the ports of Norway, Iceland, and Greenland. For verily in those days whosoever tried to outwit the Hansa was likely to prove the victim of his own plots. Circumstances aided the Germans, enabling them to make their power felt just when England had to betray weakness. The feeble and stormy period of Henry VI., often deposed and made prisoner, the Wars of the Roses, the long and continual hostilities waged with France, all favoured the League, and made the English submit to its demands rather than attract to themselves yet more enemies. In no place, not even in Bergen, did the Hanseatics succeed in enjoying greater independence. Their factory was privileged, and while benefiting by English law, they were quite independent of it. Everything, therefore, was favourable to their commerce, and they were hampered by no such restrictions as weighed, not only upon other foreigners, but upon the English themselves. To give a just idea of the degree of power to which their privileges and trade had raised the League, let us cite one example. It will serve in lieu of many, and it places in full light the almost incredible ascendency which a company of merchant cities, isolated and distant from each other, had gained over a great kingdom and a proud and valiant nation.
