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. Through 1416 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, and the consent of John of Burgundy to conclude an alliance, encouraged Henry to resume his attempt to recover Normandy. Whatever may have been his aim in this enterprise--whether it were, 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 in July 1417 with an army of forty thousand men near the mouth of the Touque, he stormed Caen, received the surrender of Bayeux, reduced Alencon and Falaise, and detaching his brother the Duke of Gloucester in the spring of 1418 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-l'Arche, 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-l'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
