Chandler, a foremost historian of Napoleonic warfare, wrote in 1973 that, "Nothing could be more degrading to the former [Napoleon] and more flattering to the latter [Hitler]. The comparison is odious. On the whole Napoleon was inspired by a noble dream, wholly dissimilar from Hitler's... Napoleon left great and lasting testimonies to his genius—in codes of law and national identities which survive to the present day. Adolf Hitler left nothing but destruction."
