Following his execution for supporting Napoleon's final return and loss of power, near the Jardin du Luxembourg on December 7, 1815, Michel Ney was quietly interred beneath a simple slab at the eastern extreme of the cemetery, in what is today division 44 grave.
His body was eventually moved to a much more elaborate tomb in division 29, near some of France's greatest military heroes: Lefebvre, Massena, Decres, Gobert, Ruty, and numerous other other generals and marshals.
