On his deathbed, Henry V detailed his plans for the war after his death. Henry bade his followers to continue the war until the Treaty of Troyes had been recognised in all of France; the Duke of Burgundy must be offered the regency of France, with Bedford as substitute should he decline; the Burgundian alliance must be preserved at all costs; the Duke of Orléans and some other prisoners must be retained until Henry's son had come of age. There would be no treaty with the Dauphin unless Normandy would be confirmed as an English possession. Bedford adhered to his brother's will, and the Burgundian alliance was preserved as long as he lived. After Henry's early death in 1422, almost simultaneously with that of his father-in-law, his baby son was crowned King Henry VI of England and II of France. The Armagnacs did not acknowledge Henry and remained loyal to Charles VI's son, the dauphin Charles. The war thus continued in central France. In 1423, the Earl of Salisbury completely defeated another Franco-Scottish force at Cravant on the banks of the Yonne river. He personally led the crossing of the river, successfully assaulting a very strong enemy position, and in the resulting battle the Scots took very heavy losses. The same year saw a French victory at the Battle of La Brossinière. The following year, Bedford won what has been described as a "second Agincourt" at Verneuil when his army destroyed a Franco-Scottish army estimated at 16,000 men. This was not a victory of the longbow for advances in plate armour had given armoured cavalry a much greater measure of protection. The heat of August meant the English archers could not implant their stakes, which led to the archers of one flank being swept away. However the English men-at-arms stood firm and waded into their enemy. Assisted by a flank attack from archers from the other wing, they destroyed the allied army. The Scots were surrounded on the field and annihilated, virtually to the last man. Approximately 6500 died there, including all their commanders. As a result, no large-scale Scottish force landed in France again. The French were also subjected to heavy punishment, as their leaders were killed on the field and the rank and file were killed or mostly dispersed. The following five years witnessed the peak of English power, extending from the Channel to the Loire, excluding only Orléans and Angers, and from Brittany in the west to Burgundy in the east.
