Jules Favier is a colonel in the French Army and one of Pierre Ducos' most trusted man. He appeared in Sharpe's Siege, and was sent by Ducos to attempt to get Sharpe to march of Bordeaux with the story that the town had risen in rebellion against Napoleon. He offered the rifleman a forged French commission as a Major General, but with his name spelled incorrectly on it. Sharpe didn't take the bait, however, so he rode with de Maquerre to the fortress of Teste de Buch and told Captain Bampfylde that there was no hope of rebellion in Bordeaux, that Sharpe was captured or dead, and he should abandon the fortress. This time the ploy worked.
