Battle of Aspern-Essling
May 21-22, 1809

The Battle of Aspern-Essling was part of the Austrian War, which in turn was part of the Napoleonic Wars.

Aspern and Essling  were located right across the Danube from Vienna.

Who fought?

France, led by the man, Napoleon I Bonaparte, himself, fought Austria. The Austrians, led by Archduke Charles, won.

French commander of the cavalry was Marshal Jean-Baptiste Bessières, the Duc d'Istrie.

Also fighting on the French side was Marshal André Masséna, the Duc de Rivoli.

The Battle of Aspern-Essling was Napoleon's first defeat, which didn't sit well with him and Napoleon came back with a vengeance a few days later to kick rear at the Battle of Wagram, which was located just a couple of minutes north of Aspern and Essling.
