The Battle of Wagram (5-6 July 1809) was one of the largest and bloodiest battles of the Napoleonic Wars (1803-1815). It resulted in a pyrrhic victory for French Emperor Napoleon I (r. 1804-1814; 1815) whose army crossed the Danube River to defeat Archduke Charles' Austrian army. #History #BattleOfWagram #BattleOfZnaim #LobauIsland #HistoryFacts https://www.worldhistory.org/article/2267/battle-of-wagram/
