The fortune of war had been oscillating with the regularity of a pendulum between England and France, when the Earl of Derby threw himself into the scale with tremendous weight, and turned it completely in England's favour. In the emphatic language of the day, he was "down upon the French like a thunderbolt." Edward went off to Flanders to treat with the free cities for their allegiance, and, in fact, ascertain the price of those friends of Liberty. Louis the Count, though deprived of nearly all his revenue, kept up his independence, and refused to pay allegiance or anything else to Edward. The English king tried to effect a transfer of the loyalty of the Flemings from Louis, the Count of Flanders, to his own son, Edward the Black Prince; and with this view he obtained the support of his old friend James von Artaveldt, the brewer, whose stout gave him a great ascendency over the actions of the people. He addressed to them a good deal of frothy declamation, and endeavoured to brew the storm of revolution; but it ended in very small beer, amid which Artaveldt himself was eventually washed away through the impetuosity of the stream he had himself set in motion. A popular insurrection broke out, and the brewer behaved with great gallantry. He wore a casque on his head which pointed him out as a butt for the malice of his enemies. He was cruelly murdered, and Edward vowed vengeance when he heard that the lifeless bier was all that remained of his friend the brewer. [Illustration: 201]
