Canterbury where he took sanctuary, but many of his officials were arrested. However, after casting himself as a second Thomas à Becket, the wily prelate then managed to shift the dispute from the administrative to the constitutional field—he accused Edward of infringing Magna Carta, insisted on the right of ministers to be tried by Parliament, and manoeuvred him into summoning one in April 1341. The Archbishop found massive support in the Parliament, and the King was wise enough to give way in return for supplies ; soon he was reconciled with Stratford. Edward knew very well that he had to keep his subjects’ support, above all that of the magnates, not only to continue with his French ambitions but to keep his throne.
Despite the subsidies granted in 1341, King Edward could not repay his loans. These included £180,000 which he had borrowed from the Florentines. In 1343 the Peruzzi, who were owed £77,000 (quite apart from interest) went bankrupt; the Bardi followed them three years later. For a short time the small group of native English financiers—among them an enterprising Hull merchant, William de la Pole, whose family will be heard of later—who controlled the wool trade tried to make a profit by lending money to the King, but in 1349 they in their turn crashed. However, by then Edward was at least able to rely on the maletote or export duty on wool. The Parliament, which included many wool producers, had at last grown reconciled to this hateful tax becoming an annual subsidy, partly because they had wrested from the King the right of controlling taxes. Indeed the growth of parliamentary power was one of the most important side effects of the Hundred Years War for the English.
In the spring of 1341 Duke John III of Brittany died. The ducal succession was disputed by Jeanne, Countess of Blois, the daughter of the late Duke’s younger brother who had predeceased him; and by John, Count of Montfort, the Duke’s half-brother. Jeanne was the niece of Philip VI, who—with a certain irony, in view of his inheritance through an exclusively male line—recognized her as Duchess of Brittany. John of Montfort thereupon sailed to England, where he acknowledged Edward to be the rightful King of France; in return he was accepted as Duke of Brittany and was also created Earl of Richmond (Robert of Artois having recently been killed). There were sound economic and strategic reasons why Edward should intervene in this struggle. On their way to Bordeaux, or to Portugal and Castile, the little English ships dared not cross the stormy Bay of Biscay but hugged the coast; it was essential that they should be able to put in at Breton ports and sail without fear of Breton privateers. A friendly Duke had to reign at Rennes if the Gascon sea-route was to be guaranteed, just as later British communications with India depended on a biddable Cairo and a biddable Aden.
A vicious little war ensued in Brittany, the lesser nobles and the peasants of the Celtic west rallying to John of Montfort, the great lords and French-speaking bourgeois of the east supporting Jeanne of Blois. In November 1341 Count John was besieged in Nantes by the French, who catapulted the heads of thirty of his knights over the walls which so terrified the defenders that they surrendered, John being taken prisoner to Paris. However, his gallant Countess kept his cause alive. She was saved by the arrival of Edward III in person in the autumn of 1342, bringing 12,000 men with him. He launched a savage chevauchée, and laid siege to the duchy’s three great cities—Rennes, Nantes and Vannes. King Philip’s son and heir, John, Duke of Normandy, marched to relieve them with a host which outnumbered the English army by at least two to one. Edward thereupon copied Philip’s precedent by digging in at a strong position. Autumn turned into a wet midwinter and soon both camps were waterlogged. In these dismal conditions Papal envoys were able to negotiate a truce in
