The Dauphin, at the age of nineteen, was crowned at Poitiers, as Charles VII. On the 12th of October, 1428, the Earl of Salisbury laid siege to Orleans, the last stronghold of any importance held by the Royalists. It was bravely defended by Glaucour, Lahyre, and Dunois. Repeated messages were sent to the king imploring assistance. The city was naturally strong, and well-garrisoned, but the English commenced an elaborate system of counter-fortification, and cut off the supplies of the besieged.

Jeanne d'Arc watched with eager anxiety the siege of Orleans. Even as a child she had learned to detest the English; and now she felt herself commanded, by frequent visions and supernatural admonitions, to undertake the deliverance of her king and country. Believing firmly that Heaven destined her to save France, she refused more than one advantageous offer of marriage. In February, 1429, being then, according to the most reliable authorities, barely eighteen, she was commanded by a vision of Our Lady to raise the siege of Orleans, and afterwards conduct Charles to Rheims to be crowned in state. She presented herself before Robert de Baudricourt, governor of Vaucoulour, a town situated a few miles from Domremy, and related her mission. Believing her to be insane, the governor twice sent her away, threatening the second time to box her ears; but when she returned a third time he thought it best to send her with letters of recommendation to the Dauphin, at Chinon, in Touraine.

The fame of Jeanne d'Arc preceded her; and the king awaited with impatience the arrival of his extraordinary visitor. Although Charles disguised himself and mixed with his courtiers, Jeanne singled him out at once, and addressed him as king of France.

After being subjected to the most severe examination during three weeks, by divines, counsellors of parliament and learned men, the king was satisfied that her story was true, and consented to accept her aid. She was furnished with a suit of armour, and armed with a sword marked on the blade with five crosses, taken by her directions from the tomb of an old warrior in the church of St. Catherine at Fierbois. In company with several nobles she was sent to the camp at Blois, thirty-five miles from Orleans. Her presence produced the most miraculous effect upon the drooping spirits of the soldiers. The French generals resolved now to make some great effort for the relief of Orleans; and ten thousand men, commanded by St. Severre, Lahyre, and the veteran Dunois were despatched to its aid. Most of the soldiers retreated in dismay when they saw the strong towers of the besiegers, but La Pucelle, followed by a small party, forced her way through the English camp, and entered Orleans on the 29th of April, 1429. She was clad in armour and mounted on a snow-white horse; her head was bare, and the long raven tresses, parted across her forehead, were tied at the back with ribbon. In her right hand she grasped a lance; by her side hung the consecrated sword and a small battle-axe.

On the 4th of May a sortie was made against the English bastille of St. Loup, but the French were driven back with great slaughter. Jeanne, hearing the noise of the fight, mounted her horse and galloped to the spot, when she rode into the midst of the battle. The French, re-animated by her presence, again charged the English, drove them back, and captured the bastille.

After this first success the rest was comparatively easy. On the 6th and 7th the remaining bastilles on the south bank of the Loire were carried by storm. The most important, that at the head of the bridge, defended by Sir William Gladsdale with five thousand picked men, yielded after an attack of fourteen hours. During the attack on this tower, Jeanne, having placed a ladder against the walls, was attempting to scale the battlements, when she was struck in the neck by an arrow. She plucked out the weapon immediately, but the loss of blood compelled her to leave the field. However, when she heard that her absence dispirited the soldiers, she insisted upon returning to the scene of action.

The Earl of Salisbury died during the siege; and the Earl of Suffolk, who succeeded to the command, raised the siege on the 8th of May, and beat a hasty retreat.

Jeanne d'Arc, the "Heaven-sent Maid," had now fully entered upon her extraordinary career of victory. The universal belief in her elevated mission—as much amongst the English as the French—produced marvellous results. Resolute and chivalrous, pious and gentle, she won the hearts of all,—even the roughest and most sceptical veterans. However, it was only in matters of moral discipline that she was implicitly obeyed; oaths or foul language were severely censured when they reached her ears. She compelled the entire army, generals and soldiers alike, to attend regularly at confession; and at every halt she ordered an altar to be established and the Holy Sacrament administered. But the generals, while they skilfully employed her to animate the soldiers, did not implicitly follow her counsels in military matters.

Her tactics were very simple. "I used," she said, "to say to them 'go boldly in among the English,' and then I used to go boldly in myself." Her duties were chiefly confined to bearing at the head of the army the consecrated sword and the sacred banner—the latter made of white satin, semée with fleurs-de-lis, with the words "Jesus Maria," and a representation of Our Saviour in his glory embroidered on its surface. Her conduct was never stained by unfeminine cruelty. It appears from the documents relative to her trial, that, although she was herself wounded many a time, she never shed the blood of anyone. Some French historians, however, aver that she did sometimes, when hard pressed, use the consecrated sword as a weapon of offence.
