After the council of war, M. d’Orleans ceased to take any share in the command, walked about or stopped at home, like a man who had nothing to do with what was passing around him. On the night of the 6th to the 7th of September, he rose from his bed alarmed by information sent to him in a letter, that Prince Eugene was about to attack the castle of Pianezza, in order to cross the Dora, and so proceed to attack the besiegers. He hastened at once to Marsin, showed him the letter, and recommended that troops should at once be sent to dispute the passage of a brook that the enemies had yet to cross, even supposing them to be masters of Pianezza. Even as he was speaking, confirmation of the intelligence he had received was brought by one of our officers. But it was resolved, in the Eternal decrees, that France should be struck to the heart that day.
Marsin would listen to none of the arguments of M. d’Orleans. He maintained that it would be unsafe to leave the lines; that the news was false; that Prince Eugene could not possibly arrive so promptly; he would give no orders; and he counselled M. d’Orleans to go back to bed. The Prince, more piqued and more disgusted than ever, retired to his quarters fully resolved to abandon everything to the blind and deaf, who would neither see nor hear.
Soon after entering his chamber the news spread from all parts of the arrival of Prince Eugene. He did not stir. Some general officers came, and forced him to mount his horse. He went forth negligently at a walking pace. What had taken place during the previous days had made so much noise that even the common soldiers were ashamed of it. They liked him, and murmured because he would no longer command them. One of them called him by his name, and asked him if he refused them his sword. This question did more than all that the general officers had been able to do. M. d’Orleans replied to the soldier, that he would not refuse to serve them, and at once resolved to lend all his aid to Marsin and La Feuillade.
But it was no longer possible to leave the lines. The enemy was in sight, and advanced so diligently, that there was no time to make arrangements. Marsin, more dead than alive, was incapable of giving any order or any advice. But La Feuillade still persevered in his obstinacy. He disputed the orders of the Duc d’Orleans, and prevented their execution, possessed by I know not what demon.
