Bedford conducted affairs in France with firmness and prudence, but he was thwarted in his policy by the thoughtless and passionate acts of his brother, the Duke of Gloucester. The latter had become smitten with Jacqueline of Hainault, the daughter and heiress of the Count of Hainault, and married, in the first instance, to the second Dauphin, John, poisoned at Compiègne. Still young at the death of that prince, she had married the Duke of Brabant; but she soon conceived a horror of her husband, who had, she said, the taste for favourites of low degree, and abandoning him after three years of union, she had taken refuge in England, where King Henry IV. had received her with great honours. He had, however, opposed the project of marriage of his brother, and upon his death-bed had recommended him to renounce them. The Pope, Martin V., had refused to break off the marriage of Jacqueline of Hainault with the Duke of Brabant; but she pleaded the degree of relationship; and addressed herself to the Anti-Pope, Benedict XIII., who had refused to submit to the decision of the Council of Constance to terminate the schism. Too happy to perform the act of a pontiff, Benedict pronounced the nullity of the marriage, and the Duke of Gloucester espoused Jacqueline of Hainault. The remonstrances of the Duke of Burgundy became more ardent; he had, from the first moment, defended the rights of his cousin, the Duke of Brabant, proposing to refer the case to the arbitration of the Duke of Bedford. "I am content," said he, "that we should take as judge my very dear and beloved cousin, and also your brother the regent, Duke of Bedford, for he is such a prince, that I know that to you and to me, and to all others, he would be an upright judge." The Duke of Gloucester had listened to no remonstrance, and the dangerous disaffection of the Duke Philip was secretly becoming graver, when, shortly after the battle of Verneuil, Gloucester and Jacqueline landed at Calais with a body of English soldiers, notwithstanding the entreaties of their uncle Beaufort in England, and those of the Duke of Bedford in France; they traversed the dominions of the Duke of Burgundy, and attacked the Duke of Brabant in Hainault; they had already taken possession of Mons when the Duke of Burgundy, in a state of fury, wrote to Gloucester, challenging him to single combat. At the same time he sent considerable assistance to the Duke of Brabant, accepting for that favour the service of his former enemies. Saintrailles was among the number of the knights who proceeded to fight against the English in the Low Countries.

The bonds which united the House of Burgundy to England were beginning to relax, and the Pope was already working secretly in concert with the Duke of Savoy, to negotiate an agreement with Charles VII. The Duke of Gloucester had returned to England; fearing the influence of his uncle Beaufort, he had left Jacqueline entrusted to defend her inheritance. Scarcely had he departed, when the majority of the towns opened their gates to the Duke of Burgundy; and Jacqueline, at first tightly held within Mons, then led a captive to Ghent, escaped with great difficulty to take refuge in Holland.

So much imprudence on the part of his nephew had irritated the Bishop of Winchester so far as to bring about an open quarrel. The Duke of Bedford was compelled to repair to England towards the end of the year 1425 to prevent bloodshed between the two parties. He had some trouble in effecting a reconciliation, sincere on the part of the Duke of Gloucester, whose character was as frank as it was impetuous; doubtful in that of the priest, more implacable than the warrior; the Bishop of Winchester resigned the seals, and finding himself elevated by Martin V. to the dignity of a Cardinalship, he quitted England with the Duke of Bedford. The latter had been recalled to France by the defection of the Duke of Brittany, who had recently declared himself in favour of King Charles VII. at the instigation of his brother, the Count of Richemont, already for some time rallied, and whom the king had made Constable. Scarcely had Bedford set foot upon French soil, when he sent an army into Brittany; the country was devastated, the Duke of Brittany was shut up within Rennes and so closely pressed, that he found himself compelled to sever his alliance with the King of France; he swore for the second time to the treaty of Troyes, and did homage to the little king Henry VI.

The Pope, Martin V., had solemnly declared the nullity of the marriage of Jacqueline de Hainault with the Duke of Gloucester, and the latter had consoled himself by espousing Eleanor Cobham, formerly a lady of the household of his wife. The Countess Jacqueline still held out bravely in Holland; the Duke of Brabant had recently died; his brother, who had succeeded him, had no claim upon Jacqueline or upon her dominions; she would have been free if the enemy whom she had raised up had not been too powerful and too greedy to stop on such a fine road; from town to town, from territory to territory, the Duke of Burgundy prosecuted his conquest, and Jacqueline, abandoned by nearly all her vassals, a victim on sea and on land, at length consented, in the summer of 1428, to recognize the Duke Philip as her heir, and to entrust to him immediately the government of her dominions. The duke, satisfied with the English, who had not hindered him in this last act of his ambition, promised troops for the great expedition which was being prepared against the country beyond the Loire, almost entirely rallied to King Charles VII.

The war had languished since the battle of Verneuil; the King of France was poor, indolent, and delivered up to favourites. The Sire de Giac and the Sire de Beaulieu had given place to the Sire de la Trémoille, more adventurous and more dangerous than the two others; he counteracted beside the king the influence of the Constable de Richemont and of the true friends of France. The Duke of Bedford for a long time paralyzed by the quarrels of the Duke of Gloucester, had recently received reinforcements from England, under the order of the Earl of Salisbury. The latter resolved to undertake the siege of Orleans. On the 12th of October, 1428, he appeared before the city, commencing his siege preparations according to the most learned rules of the time, but not considering that he had given time for the place to furnish itself with men and victuals, to repair its fortifications, and to place itself in a state of defence; the best knights of the King of France had shut themselves up in Orleans.

The assaults failed, the citizens of Orleans valiantly supporting the garrison. The Bastard of Orleans, Count of Dunois, had brought reinforcements, Salisbury dreamt of metamorphosing the siege into a blockade, when, contemplating the city from the Tournelles fort, which he had taken at the outset, he was struck in the face by a stone shot from a falconet, which rebounded against the embrasure of the window and killed his esquire beside him. The general was dying; it was found necessary to carry him to Fertê-sur-Meung, where he died at the end of a few days, to the great joy of the population of Orleans. The Earl Suffolk arrived to take the command, and the siege continued. The English army, badly installed beneath its huts of tree branches, suffered from the cold, and often from hunger; the country which surrounded them was hostile and devastated; the Duke of Bedford resolved, in the month of February, to send provisions to him from Paris. It was during Lent and the convoy which Sir John Falstaff was entrusted to lead, consisted especially of herrings, when, on the 12th of February he was attacked by the French near the village of Rouvray, between Graville and Orleans. As usual, the Scotch and the French quarrelled among themselves; the former, wishing to fight on foot, the latter to remain on horseback; they were within bowshot, and the English archers were beginning to shoot; the rout was not long delayed, and Sir John Falstaff arrived triumphantly at the camp with the herrings which gave their name to his victory.

This defeat threw discouragement into Orleans; hunger began to make itself felt; the citizens spoke of surrendering their city, not to the English but the Duke of Burgundy; the latter came to Paris to consult about it with the regent. "No," said Bedford, "it is just that those who have had the trouble should have the honour." Philip did not remonstrate; disquieting rumours were beginning to circulate among the Burgundians: it was said that the Duke of Bedford had declared that the Duke of Burgundy would finally proceed to England to drink more beer than would quench his thirst. The duke quitted the court, dissatisfied and gloomy. The King of France was at Chinon; his affairs appeared desperate; many noblemen had abandoned him, and he would have willingly retired to the South, abandoning to their fate Orleans and the banks of the Loire, but for the efforts of his wife, Mary of Anjou, and the anger of Dunois. La Trémoille had caused the Constable to be sent away.

Deliverance was approaching by the weakest instrument which it has ever pleased God to employ for the accomplishment of His designs. A young girl was growing up in the village of Domrémy, upon the borders of Lorraine and Burgundy; she was named Joan of Arc, she was eighteen years of age, she was good and pious. For a long while already—from the age of thirteen years—she had begun to have visions, to hear voices, Saint Michael, Saint Catherine, and Saint Margaret commanding her to go to France, to the assistance of the king: as she grew up the voices became more urgent. People began to speak in the village of the strange exaltation of Joan. The Sire de Baudricourt, in command at Vaucouleurs, wished to see her; but he sent her back ridiculing her. Urged however, by others, he resolved to cause her to be taken to the king. "I must go to the king before Mid-Lent," said Joan, "even should I have to wear my legs to the knees to reach him, for nobody in the world, neither king nor duke, nor daughter of the King of Scotland can deliver the kingdom of France; I should prefer to remain and spin beside my poor mother, for it is not my work, but I must go, because Messire wills it." "Who is Messire?" it was asked. "It is God," said Joan, and the noblemen who were leading her forward were struck with admiration on seeing her pass the night kneeling in the churches, and fasting on bread and water.
