Indeed, one of the principal reasons for Napoleon's 1815 comeback failing to clear the group stages was the odd reshuffle of his loyal marshals and the no-show by significant others. Neither Ney nor Grouchy had experience in fighting the British Army (Ney had served briefly in Spain during the Corunna Campaign of 1809 and Grouchy not at all), Soult, who had, was not given a command. His other most experienced Peninsular Marshals, Massena and Marmont, had refused to support the Hundred Days. Of the others, Mortier was unable to participate due to Sciatica and Berthier died at the outset of the Campaign under mysterious circumstances.
Most returned to service with the King after Napoleons exile. One of my favourite Wellington stories concerns his invitation to a soiree in Paris during his time as British Ambassador. As he entered the room, a number of Napoleon's former Marshals, who had also been invited, turned away from him. This embarrassed the hostess, but to whom the Duke replied "...worry not Madame, for I have seen their backs before..."
