Battle of Wagram

After the defeat at Essling and the numerous losses counted by the French army, Napoleon decided to repopulate his ranks by requisitioning troops from Italy, Dalmatia and Poland to push back the Austrian troops who threatened to take the island of Lobau housing the Grand Army. If the victory of the French in this battle definitively repels the offensive of the Archduke of Austria, it is about one of the deadliest fights that there have been up to that point during the Napoleonic campaigns, since we can count nearly 40,000 losses among the French, including General Lasalle who joined Lannes in death. Many see it as a mark of the Emperor's future defeats.
The Battle of Wagram took place under the walls of Vienna, which can be seen at the top of the print.
