Whilst Sigismund was anxiously engaged in endeavouring to bring the two nations to terms of peace, news arrived of an event which must have made his efforts and mediation appear hopeless. The French had fallen upon part of the garrison of Harfleur, and cut off a considerable body of them. Not long after this, and whilst negociations were pending between London and Paris, with a more favourable appearance of a successful issue, tidings came that the French fleet had scoured the Channel, had blockaded Southampton, and had made various attempts on the Isle of Wight; that the Constable, D'Armagnac, had recalled them, and they were then besieging Harfleur. Henry and his council resolved on making an immediate and vigorous effort to destroy that fleet; and forthwith an armament was prepared, of which Henry expressed his determination to take the command himself. At the urgent request, however, of the Emperor, he desisted from that resolution, and gave the supreme command to his brother the Duke of Bedford; who, after a most obstinate battle, gained a decided victory over the enemy, and relieved Harfleur.[157]

The Emperor was soon convinced that his mediation must fail, and that France was resolved to renew the war. He then determined not to remain neutral, but to join himself by a solemn league with Henry. The preamble of this covenant is deeply interesting, as indicative, at least, of the professed sentiments of Sigismund with regard to the pretensions of Henry, and to the conduct and character of the two belligerent kings. Sigismund declared the object of his desire to have been the restoration of peace to the church and to Christendom; and, with that end in view, he had endeavoured to reconcile the Kings of England and France, but without success. The failure he ascribed entirely to the hatred of peace which influenced the French King, to whom he attributed also the prevalence of schism in the church, and the disturbed state of the Christian world. He then expresses his resolution "to form a league with Henry in the name of the Lord God of Hosts, and to assist him in the recovery of his JUST RIGHTS."[158] This league was signed August 15, 1416. The Emperor, shortly after this unlooked-for termination of his office as mediator, left England. Before he had proceeded onwards from Calais, Henry himself arrived at that town. After some days, the Duke of Burgundy also joined them; and much time was spent in secret negociations, the nature of which did not transpire, though we may suppose both the Emperor and King were anxious to make him a party to the league already concluded between themselves. A covenant, however, was signed by the Duke early in October, in which he declared that, "though he had taken part with the enemies of Henry in time past, yet now, being assured of his lawful claim, he would employ his arms in his service as the rightful King of France."

The Emperor left Calais for Germany; and Henry, having concluded a truce with France till the 2nd of February, returned to England, and met his parliament on October 19th. Much zeal was here shown in his behalf; and whilst the parliament granted two whole tenths and two whole fifteenths, to be levied on the laity, the clergy gave two tenths, to be paid by their own body. But all this was not enough; recourse was again had to borrowing, the Dukes of Clarence, Bedford, and Gloucester pledging themselves, in case of Henry's death, to the repayment of the loans. Henry pawned a valuable crown to his uncle, the Bishop of Winchester, for money to a great amount; and he pledged very valuable jewels to the Mayor of London for another large sum. No measure was left untried, that Henry might be prepared by the ensuing spring with men and money for the invasion of France.[159] In the meanwhile, the French princes and nobles who had been taken prisoners at Agincourt were anxiously negociating for their release. In a communication of strict confidence to the Emperor, Henry declares that all their proceedings were suspicious, and selfish, and deceitful; that he had suffered the Duke of Bourbon to return to France on certain conditions, but that the Emperor might be assured of his resolution to invade that country.

Henry's exertions were effectual; and, soon after midsummer, he found himself prepared with men and money to renew his expedition to Normandy in a fleet of fifteen hundred sail, and with an army of not less than twenty-five thousand soldiers. Before he embarked, however, he commissioned Holland, Earl of Huntingdon, whose father had been beheaded at Cirencester in the reign of Henry IV, with a squadron to scour the seas, and secure a free passage for the transports. The Earl was successful in a most hard-fought battle with a fleet of Genoese large ships, sent by their republic[160] to aid the French King; and on July 23rd 1417, Henry set sail for the coast of France.[161] A large body of French on the shore threatened to oppose him; but he landed his forces safely, on the 1st of August, at Beville. As soon as his people were all safe on shore, by an act characteristic of himself, he adopted the same measure which, on his former expedition, had compelled him to make his way to Calais by land. He dismissed all his ships homeward, excepting what were required for transporting cannon; thus assuring his soldiers that they must conquer or die, for they had no retreat.

Henry found the country altogether deserted, the inhabitants having fled from their homes in every direction on receiving the alarming tidings of his approach. It is said that twenty-five thousand families fled into Brittany; and so complete was the evacuation in some districts, that there reigned through the country the stillness of death. In Lisieux, a considerable town eighteen miles from the sea, the English found but one old man and one woman. The people had secured themselves, to the utmost of their means, in fortified towns, all of which had been supplied with strong garrisons on the first news of the intended invasion.

Henry systematically caused the most strict discipline to be observed in his army, of which many proofs are recorded. Among other instances we read that when a monk complained of having been robbed by a soldier, he was desired to fix upon the guilty man. On discovering the culprit, the King upbraided him with his baseness, and pronounced him worthy of death; but, on making restitution, and promising never again to be guilty of the offence, he pardoned him. "And you, friend," said he, turning to the monk, "go back to your brethren in peace, and attend all of you to your sacred duties without fear of me or my army. I am not come hither as a thief to rob your churches and altars, but as a just and merciful King to protect you from violence." Henry then proclaimed through the army that no one should injure an ecclesiastic on pain of death.[162] It was amusing, we are told, to see how the numbers of the regular clergy were suddenly swollen; rustics shaving their heads, and putting on the dress of a monk, to be safe under the terms of that protection.

During this campaign Henry sent repeated bulletins of his proceedings and successes to the mayor and aldermen of London, many of the originals of which are still in existence; and which combine, with the answers to them, in bearing evidence to the popularity of Henry's person, and of the cause in which he was embarked. Some of these documents are exceedingly interesting; but it would be needless to transfer them all into these pages.[163] It is to be lamented that such indisputable records are not all published, or rendered accessible to every one who would wish to consult them. The interspersion of a few in this part of the volume may enable the reader to verify in more points than one the views which are here offered of Henry's character and the feeling of the people of England at this period. The first is a letter from Henry himself, dated August 9, 1417, at Touque, the very day of the surrender of that place, and only a week after he landed.

"Trusty and well-beloved, we greet you oftentimes well; doing [giving] you to understand for your comfort, that, by the grace of God, we be safely arrived into our land of Normandy, with all our subjects ordained to go with us for the first passage. And this day, the even of St. Lawrence, about mid-day, was yolden [yielded] unto us the castle of Touque, about the which our well-beloved cousin, the Earl of Huntingdon, lay; and the keys of the said castle delivered unto us without the shedding of Christian blood, or defence made by our enemies:—the which castle is an honour, and all the viscounty and lordships of Ange hold thereof, as we have been informed of such men as were therein. Whereof we thank God lowly, that hym lust [he is pleased] of high grace to show unto us so fair beginning in our present voyage; desiring also that ye thank God thereof in the most best wise that ye can, and that ye send us from time to time such tidings be komerys be thwene [by comers between], as ye have in that side the sea. Given under our signet, at our said Castle of Touque, the 9th day of August.

"To the Mayor, Sheriffs, Aldermen, and good people of our City of London."—Endorsed in French.

But though Henry speaks thus encouragingly of his present campaign, he had soon much to make him anxious, and to rouse all the energies of his mind. Among other sources of solicitude was the growing evil of desertion. Many of his soldiers grew tired of the war, and, dishonourably leaving his camp, stole back to their native country. Of the prevalence of this mischief we have too clear proof in the following writ, a copy of which was despatched to all the sheriffs of England. It is found among the Norman Rolls, and is one of the few specimens with which Mr. Hardy has enriched the interesting introduction to his edition of those valuable documents.[164]
