Joan disembarked and proceeded, according to her custom, to examine the entrenchments that she contemplated assailing. Not far from the bastille of St. John-le-Blanc rose the Augustinian Convent, composed of massive buildings that were strongly fortified. Beyond that, the bastille of the Tournelles, a veritable citadel flanked with high wooden towers, spread its wings towards the Beauce and Touraine and faced the bridge of Orleans that had long been cut off by the enemy. Still another formidable redoubt, that of St. Privé, situated to the left and not far from the Tournelles completed the besieging works of the English to the south of the town. The martial maid proposed to carry the four formidable positions one after the other, after which the English would be compelled to abandon the other and less important bastilles which they had raised to the west, these being incapable of resistance after the destruction of the more important works. Joan long and leisurely observed the approaches of these works and revolved her plan of attack. Her woman's clothes aroused no suspicion with the English sentinels. After she had gathered full information with a quick and intelligent eye, she returned to her boat and re-entered the house of Master Boucher so well wrapped in her mantle that she actually escaped the observation of all eyes. She forthwith resumed her male attire to attend the high mass, where she again took the communion. The enthusiastic acclamations that broke out along her route to and from the church proved to her that she could count with the support of the people of Orleans. She entered the house of Master James Boucher where the captains and councilmen were gathered. The council soon went into session, but Joan was not summoned at the start.

At this session there assisted the magistrates of the town as well as Xaintrailles, Dunois, Marshals Retz and St. Sever, the Sire of Graville, Ambroise of Loré, Lahire and other captains. The Sire of Gaucourt presided in his quality of royal captain.[83] The recent victory of the Maid, a victory in which several of the captains least hostile to her had played a secondary role, inspired them all with secret and bitter envy. They had expected to serve themselves with the young peasant girl as a passive instrument of their will, to utilize her influence to their own advantage and to issue their commands through her. It had turned out otherwise. Forced, especially after the battle of the day before, to admit that Joan excelled them all in the profession of war, irritated at the injury done to their military fame, and convinced that the military successes would be wholly placed to the credit of Joan, the one time less hostile captains now went wholly though secretly over to her pronounced enemies, and the following plan of battle was unanimously adopted for the morrow:

"A feint shall be made against the fortress of the Tournelles in order to deceive the enemy and cause it to sally out of the redoubts that lie on the other side of the Loire and hasten to bring help to the threatened position. The enemy will be readily duped. A few detachments shall continue skirmishing on the side of the Tournelles. But the royal troops and the companies of mercenaries will move upon and easily capture the other bastilles where the English, in their hurry to hasten to the defence of an important post, will have left but feeble garrisons behind."[84]

This plan of battle, whether good or bad from the viewpoint of strategy, concealed an act of cowardly perfidy, an infamous, horrible snare spread for Joan. Speaking in the name of the councilmen, and answering the Sire of Gaucourt, who explained the plan that the captains had adopted, Master James Boucher observed that the Maid should be summoned so as to submit to her the projects of the council.

The Sire of Gaucourt hastened to object in the name of all the captains, on the ground that they were not sure the young girl would know how to keep so delicate a matter secret, and that, seeing the doubt existed, she should be informed only upon the plan of attack against the Tournelles, but should not be apprised that the manoeuvre was only a feint, a ruse of war. Accordingly, during a skirmish commanded by the Maid in person, the bulk of the army was to carry out the real plan of battle, on which Joan was to be kept in the dark.[85]

The infernal snare was skilfully planned. The captains relied upon the Maid's intrepidity, certain that she would march without hesitation at the head of a small number of soldiers against the formidable Tournelles, and they did not doubt that in such an assault, as murderous as it was unequal, she would be either killed or taken, while the captains, sallying from Orleans at the opposite side and at the head of the bulk of the troops, would proceed against the other bastilles, that were expected to be found almost wholly deserted by the English, who would have hastened to the aid of the defenders of the Tournelles. Finally, Joan having on the previous day taken an emphatic stand against the captains' opinion, and maintained that the raising of the siege of Orleans depended almost wholly upon the capture of the Tournelles, and that that important work should be forthwith attacked, it was expected she would imagine her views had been adopted by the council of war after mature reflection, and that, carried away by her courage, she was certain to march to her death. Thus the plot concocted long before by the Sire of La Tremouille, Gaucourt and the Bishop of Chartres was now to be put into execution.

Despite their mistrust of the captains, the councilmen failed to scent the trap laid for the Maid. She was introduced, and Gaucourt informed her of the decision of the council omitting, however, to say that the attack upon the Tournelles was only to be a feint. Gifted with rare good sense and sagacity, the Maid had too many proofs of the constant opposition that until then all her plans had met from the captains not to be astonished at seeing them suddenly adopt a plan that they had so loudly condemned the day before. Suspecting a snare, she listened silently to Gaucourt while pensively pacing up and down the hall. When he ended she stopped walking, fixed her frank and beautiful eyes upon the traitor and said boldly:

"Seigneur Gaucourt, do not hide from me anything of what has been decided. I have known and shall know how to keep other secrets than yours."[86]

These words, through which the Maid's mistrust of the captains plainly peeped, confused them. They looked at each other dumbfounded and uneasy. Dunois, the least depraved of all, felt the pangs of remorse and could not decide to remain an accomplice in the execrable scheme of betrayal. Still, not wholly daring to uncover it, he answered:

"Joan, do not get angry. You can not be told everything at once. You have been made acquainted with the first part of our plan of battle. I must now add that the attack upon the Tournelles is to be a feint, and while the English come to the help of their fellows and cross the Loire, we shall attack in good earnest their bastilles over in the Sologne, which they will have left almost empty of defenders."
