One of her best historians, M. Wallon, thinks that the words which she is supposed to have spoken to the people in the Church of Saint James at Compiègne were owing to her discouragement at not having, a few weeks previously, been able to cross the river Aisne at Soissons, and thus finding herself prevented from attacking the Duke of Burgundy at Choisy, and thence having been obliged to return to Compiègne. Wallon points out that in coming to defend Compiègne, Joan of Arc came entirely at her own instigation, and that during the previous six months Flavy had defended Compiègne against the English and Burgundians with success and energy; nay more, that, in spite of bribes from the Duke of Burgundy, Flavy contrived to hold the town till the close of the war.
On the other side, a recent writer of the heroine's life, especially as regarded from a military standpoint, M. Marin, gives at great length his reasons for believing in the treachery of Flavy. M. Marin points out that, in the first place, Flavy's character was a notoriously bad one; secondly, that he was very possibly under the influence of both La Tremoïlle and the Chancellor Regnault de Chartres, bitter opponents, as we have already shown, of the Maid; thirdly, that it was in Flavy's interest that the prestige of saving Compiègne from the Burgundians and English should be entirely owing to his own conduct; and fourthly, that he, Flavy, with the majority of the French officers, was affected against Joan of Arc since the execution of Franquet d'Arras. M. Marin goes on to prove that Joan of Arc might have been rescued without difficulty, and that the enemy could not have forced their way into the town alongside of the retreating French, unless they were ready to be cut up as soon as they had come within its walls. M. Marin's opinion, having the authority of a soldier, carries weight with it; and his opinion is that Joan of Arc was deliberately betrayed by Flavy, and purposely allowed to fall into the hands of her enemies.
The names of La Tremoïlle and Regnault de Chartres should also be pilloried by the side of that of Flavy--the two great courtiers who held the ear of the King, and who had always plotted against Joan of Arc. As has already been said, it was Regnault de Chartres who had the effrontery to announce the news of Joan of Arc's capture to the citizens of Rheims as being a judgment of Heaven upon her. She had, this mean prelate said, offended God by her pride, and in wearing rich apparel, and in having preferred to follow her own will rather than that of God! Verily, and with reason, might poor Joan have prayed to be delivered from such friends as those creatures and courtiers about her King, for whom she had done and suffered so much.
