When Paris fell and the Bourbons reclaimed the throne, Ney was promoted and lauded. When he was sent to arrest Napoleon however, he was convinced by Napoleon to switch sides once again.
When Napoleon was defeated for the second time, Ney was executed by firing squad, in Paris near the Luxembourg Garden, refusing the blindfold, and being allowed the right to give the order to fire.

MICHEL NEY, duke of Elchingen, prince of the Moskowa (1769-1815), marshal of France, was born at Saarlouis on the Toth of January 1769.
At the fall of the Empire Ney was neither the first nor the last of the marshals to give up the struggle, but that he acted in the negotiations in concert with Macdonald and Caulaincourt is sufficient proof of his desire to avert the unreserved abdication that was forced upon Napoleon by other circumstances.
Ney was placed on trial before a courtmartial composed chiefly of his former brothers-in-arms, whose participation in the tragedy, slight as it was, was probably never forgiven them by their countrymen.
