Finding that his plots were of no avail, he essayed to get together an army large enough to combat his father, but before he completed his plans, Charles VII, tired of his endless treason and trickery, sent an army, under the faithful de Chabannes, into the Dauphiné, with orders to arrest the Dauphin.
The forces which Louis had at his disposal were numerically so much weaker, that he did not dare to risk a battle.
“If God or fortune,” he cried, “had been kind enough to give me but half the men-at-arms which now belong to the King, my father, and will be mine some day, by Our Lady, my mistress, I would have spared him the trouble of coming so far to seek me, but would have met him and fought him at Lyon.”
Not having sufficient forces, and feeling that he could not hope for fresh pardon, he resolved to fly from France, and take refuge at the Court of the Duke of Burgundy.
One day in June, 1456, he pretended to go hunting, and then, attended by only half a dozen friends, rode as fast as he could into Burgundian territory, and arrived at Saint Claude.
From there he wrote to his father, excusing his flight, and announcing his intention of joining an expedition which Philippe le Bon, the reigning Duke of Burgundy was about to undertake against the Turks. The Duke was at that moment besieging Utrecht, but as soon as he heard the Dauphin had arrived in his dominions, he sent orders that he was to be conducted to Brussels with all the honours befitting his rank and station.
Shortly afterwards the Duke returned, and listened with real or pretended sympathy to all the complaints that Louis made against his father, but put a damper on any hopes that the Prince may have entertained of getting the Burgundian forces to support his cause, by saying;
“Monseigneur, you are welcome to my domains. I am happy to see you here. I will provide you with men and money for any purpose you may require, except to be employed against the King, your father, whom I would on no account displease.”
Duke Philippe even tried to bring about a reconciliation between Charles and his son; but as Louis was not very anxious to return to France, nor Charles to have him there, and a good many of the nobles were far from desiring that the Prince should come back, the negotiations came to nothing.
Louis could make himself agreeable when he pleased, and during his stay in the Duke’s domains, he was on good terms with Philippe le Bon, who granted him 3000 gold florins a month, and the castle of Genappe as a residence. This castle was situated on the Dyle, midway between Brussels and Louvain, and about eight miles from either city. The river, or a deep moat, surrounded the castle on every side. There was a drawbridge which was drawn up at night, so Louis felt himself quite safe from any attack.
