Memoires du Marechal Marmont, Duc de Raguse by Auguste Marmont.
"The story of a brilliant man, trying to justify himself before a hostile generation-largely by throwing the blame on others. Marmont took an intelligent interest in soldiering and the problems of command; his book remains a must for every student of this period, both for its professional content and its unconscious self-portrait of a soldier who was too willing to listen to politicians and his own vanity. He remains, however, an untrustworthy witness, where his own conduct comes into question."

More on Marmont's character from Swords Around A Throne by John Elting, 140:
"...[Marmont] fought through 1813 and 1814 in Germany and France, often with success-until, in a fit of discouragement, he listened to Talleyrand's wheedling and went over to the allies."
"One of the most intelligent and best educated of the marshals, Marmont also surpassed most of them as an administrator and organizer. As a tactician he was courageous, imaginative, quick, and deadly. His vanity rendered him ungrateful to superiors and subordinates alike, but he was not meanly selfish: In 1815 he risked the Bourbons' anger in an attempt to save Antoine Lavalette from execution. With all his abilities, there was an unsteadiness about him; periodically he was seized-sometimes at most unfortunatel moments-by spasms of depression or carelessness."
"After Waterloo, cherished by the Bourbons, he lived extravagantly, losing large sums in attempts at scientific farming. He also diddled with the War Ministry's files to improve the history of his 1813 operations. In streets and barracks, his Napoleonic title Duke of Ragusa inspired the new verb raguser-to cheat, sneak, betray. In 1830, when France rose against its Bourbon King, he failed to quell the Paris mob and so fled into exile. He had little money left and, when he passed, children whispered that there went the man who betrayed Napoleon.'
Turning your command over to the enemy is not being 'loyal to la patrie.' Not only did he violate his oath of service, he betrayed his own troops as they did not know what was going on until they were inside the enemy's lines.
