She was abandoned by the Dauphin and the French Court
Despite all she had done for the Crown of France, they did nothing to save her. They could have entered into negotiations to ransom her from the Burgundians. They could have exchanged her for some Burgundian prisoners. The new King had quickly forgotten how much he had owed the young girl from the country. Ultimately, Joan despite her undoubted gifts was only a peasant girl and was, therefore disposable. It is highly unlikely that the English would have returned her to the French but the king could have tried. After Joan had been captured she was soon forgotten by the Frenc Court and she was by all accounts never mentions. Her role in the wars and her contributions to the revival of French power was also forgotten and downplayed.
