Rothenberg, Gunther.THE EMPEROR'S LAST VICTORY: NAPOLEON AND THE BATTLE OF WAGRAM. London Weidenfield & Nicolson 2004 First edition 272pp, 8pp color plates, fine in dj. Wagram was Napoleon's last decisive victory, because the Austrians had adopted Napoleon's tactic of massed artillery fire ('At last they have learned something!') and because of the re-organization of the Austrian army into independent corps. An excellent study.
