The immediate result of the battle of Agincourt was small, for the English army was too exhausted for pursuit, and it made its way to Calais only to return to England. The war was limited to a contest for the command of the Channel, till the increasing bitterness of the strife between the Burgundians and Armagnacs encouraged Henry to resume his attempt to recover Normandy. Whatever may have been his aim in this enterprise - whether it wore, as has been suggested, to provide a refuge for his house, should its power be broken in England, or simply to acquire a command of the seas - the patience and skill with which his object was accomplished raise him high in the rank of military leaders. Disembarking with an army of 40,000 men, near the mouth of the Touque, he stormed Caen, received the surrender of Bayeux, reduced Alengon and Falaise, and detaching his brother the Duke of Gloucester to occupy the Cotentin, made himself master of Avranches and Domfront. With Lower Normandy wholly in his hands, he advanced upon Evreux, captured Louviers, and, seizing Pont-de-PArche, threw his troops across the Seine. The end of these masterly movements was now revealed.

Rouen was at this time the largest and wealthiest of the towns of France; its walls were defended by a powerful artillery; Alan Blanchard, a brave and resolute patriot, infused the fire of his own temper into the vast population; and the garrison, already strong, was backed by fifteen thousand citizens in arms. But the genius of Henry was more than equal to the difficulties with which he had to deal. He had secured himself from an attack on his rear by the reduction of Lower Normandy, his earlier occupation of Harfleur severed the town from the sea, and his conquest of Pont-de-1'Arche cut it off from relief on the side of Paris. Slowly but steadily the King drew his lines of investment round the doomed city; a flotilla was brought up from Harfleur, a bridge of boats thrown over the Seine above the town, the deep trenches of the besiegers protected by posts, and the desperate sallies of the garrison stubbornly beaten back. For six months Rouen held resolutely out, but famine told fast on the vast throng of country folk who had taken refuge within its walls. Twelve thousand of these were at last thrust out of the city gates, but the cold policy of the conqueror refused them passage, and they perished between the trenches and the walls.

In the hour of their agony women gave birth to infants, but even the new-born babes which were drawn up in baskets to receive baptism were lowered again to die on their mothers' breasts. It was little better within the town itself. As winter drew on one-half of the population wasted away. "War," said the terrible King, " has three handmaidens ever waiting on her, Fire, Blood, and Famine, and I have chosen the meekest maid of the three." But his demand of unconditional surrender nerved the citizens to a resolve of despair; they determined to fire the city and fling themselves in a mass on the English lines; and Henry, fearful lest his prize should escape him at the last, was driven to offer terms. Those who rejected a foreign yoke were suffered to leave the city, but his vengeance reserved its victim in Alan Blanchard, and the brave patriot was at Henry's orders put to death in cold blood.

A few sieges completed the reduction of Normandy. The King's designs were still limited to the acquisition of that province; and pausing in his career of conquest, he strove to win its loyalty by a remission of taxation and a redress of grievances, and to seal its possession by a formal peace with the French Crown. The conferences, however, which were held for this purpose at Pontoise failed through the temporary reconciliation of the French factions, while the length and expense of the war began to rouse remonstrance and discontent at home. The King's difficulties were at their height when the assassination of the Duke of Burgundy at Montereau, in the very presence of the Dauphin with whom he had come to hold conference, rekindled the fires of civil strife. The whole Burgundian party, with the new Duke, Philip the Good, at its head, flung itself in a wild thirst for revenge into Henry's hands. The mad King, Charles the Sixth, with his Queen and daughters, were in Philip's power; and in his resolve to exclude the Dauphin from the throne the Duke stooped to buy English aid by giving Catharine, the eldest of the French princesses, in marriage to Henry, by conferring on him the Regency during the life of Charles, and by recognizing his succession to the crown at that sovereign's death.

The treaty was solemnly ratified by Charles himself in a conference at Troyes, and Henry, who in his new capacity of Regent had undertaken to conquer in the name of his father-in-law the territory held by the Dauphin, reduced the towns of the Upper Seine and entered Paris in triumph side by side with the King. The States-General of the realm were solemnly convened to the capital; and strange as the provisions of the Treaty of Troyes must have seemed, they were confirmed without a murmur, and Henry was formally recognized as the future sovereign of France. A defeat of his brother Clarence in Anjou called him back to the war. His reappearance in the field was marked by the capture of Dreux, and a repulse before Orleans was redeemed by his success in the long and obstinate siege of Meaux. At no time had the fortunes of Henry reached a higher pitch than at the moment when he felt the touch of death. But the rapidity of his disease baffled the skill of physicians, and with a strangely characteristic regret that he had not lived to achieve the conquest of Jerusalem, the great conqueror passed away.
