To decorate the bridge of Iéna, Napoleon 1st had planned to make install in the extremities of the work the equestrian statues of four generals of the Grande Armée killed during the campaign of Prussia (1806). Four sculptured groups installed in the entrances of the bridge indeed show horses guided by warriors. On piles, eagles sculptured by Barye in 1850 replaced the figure of Louis XVIII set up under the Restoration in substitution of the imperial Eagle.
