Henry VIDuring the 1430s the search for peace became more urgent, particularly in England. The Congress of Arras (1435) and discussions at Gravelines (1439) were unproductive, largely because English opinion remained divided as to the desirability of peace and the wisdom of significant concessions. But the recovery in Charles VII's fortunes, the mounting cost of English Still at War, 1390-1490 231 expeditions to defend Lancastrian France, Bedford's death in 1435, and especially the defection of Burgundy were decisive factors. The government freed the duke of Orleans (a captive in England since Agincourt) to promote peace among his fellow French princes (1440), though he did not have much success. In 1445 Henry VI married the French queen's niece, Margaret of Anjou, but even that only produced a truce, and a proposed meeting of kings never took place. Eventually, Henry VI promised to surrender hard-won territory in the county of Maine as an earnest of his personal desire for peace. His failure to win the support of his subjects for this move—especially those magnates and gentry who had lands in France and had borne the brunt of the fighting—led to the exasperated French attacking Normandy in 1449. Their onslaught, supported by artillery, was so spectacularly successful that the English were defeated at Rouen and Formigny, and quickly cleared from the duchy by the end of August 1450. ' . . . never had so great a country been conquered in so short a space of time, with such small loss to the populace and soldiery, and with so little killing of people or destruction and damage to the countryside,' reported a French chronicler.
Gascony, which had seen few major engagements under Henry V and Henry VI, was invaded by the triumphant French armies, and after their victory at Castillon on 17 July 1453, the English territories in the south-west were entirely lost. This was the most shattering blow of all: Gascony had been English since the twelfth century, and the long-established wine and cloth trades with southwest France were seriously disrupted. Of Henry V's 'empire', only Calais now remained. The defeated and disillusioned soldiers who returned to England regarded the discredited Lancastrian government as responsible for their plight and for the surrender of what Henry V had won. At home, Henry VI faced the consequences of defeat.
Within three weeks of Castillon, Henry VI suffered a mental and physical collapse which lasted for seventeen months and from which he may never have fully recovered. The loss of his French kingdom (and Henry was the only English king to be crowned in France) may have been responsible for his breakdown, though by 1453 other aspects of his rule gave cause for grave concern. Those in whom Henry confided, notably the dukes of Suffolk (murdered 1450) and Somerset (killed in battle at St. Albans, 1455), proved unworthy of his trust and were widely hated. Those denied his favour—including Richard, duke of York and the Neville earls of Salisbury and Warwick— were bitter and resentful, and their efforts to improve their fortunes were blocked by the king and his court. Henry's government was close to bankruptcy, and its authority in the provinces and in Wales and Ireland was becoming paralysed. In the summer of 1450, there occurred the first popular revolt since 1381, led by the obscure but talented John Cade, who seized London for a few days and denounced the king's ministers. The king's personal responsibility for England's plight was inevitably great.
Henry VI was a well-intentioned man with laudable aspirations in education and religion; he sought peace with France and wished to reward his friends and servants. But no medieval king could rule by good intentions alone. Besides, Henry was extravagant, over-indulgent, and did not have the qualities of a shrewd and balanced judge of men and policies. He was intelligent and well educated, but he was the least experienced of kings and never shook off the youthful dependence on others which had been the inevitable hallmark of his long minority (1422-36). Many of his problems were admittedly unavoidable. The dual monarchy created by his father made heavier and more complex demands than those placed on a mainly military conqueror such as Edward III or Henry V. His minority was a period of magnate rule which created vested interests that were not easily surrendered when the king came of age—particularly by his uncle, Humphrey, duke of Gloucester, and his greatuncle, Henry Beaufort, cardinal-bishop of Winchester. Moreover, after Gloucester's death in 1447, Henry was the only surviving descendant of Henry IV in the senior male line, a fact which Still at War, 1390-1490 233 led him to distrust the duke of York, the heir of that earl of March who had been passed over in 1399. There was, then, ample reason for disenchantment with late Lancastrian rule, and in Richard of York there was a potential leader of the discontented.
Despite the king's illness, the birth of a son to his abrasive queen in October 1453 strengthened the Lancastrian dynasty, but it hardly improved the immediate prospect for the realm or for Richard of York. As England's premier duke and Henry's cousin, York was twice appointed protector of the realm during the king's incapacity (1454-5, 1455—6). But as such he aroused the queen's fierce hostility which erupted in the battles of Blore Heath and Ludford Bridge (September-October 1459), and in the subsequent Parliament at Coventry which victimized York, the Nevilles, and their supporters. This alienation of powerful men by a regime with a disastrous record at home and abroad led York to claim the Crown in October 1460. After his death at Wakefield soon after, his son Edward took it for himself on 4 March 1461, with the aid of the earl of Warwick. The period of dynastic war that is popularly known as the Wars of the Roses was now well under way amid conditions that had been ripening during the 1450s.
