Count of the Empire Pierre-Louis Dupas was a French soldier who rose to prominence during the French Revolutionary Wars, was noted for his association with Napoleon Bonaparte, and rose to the top military rank of General of Division during the Napoleonic Wars. A fiery commander, often noted for bravery, Dupas was often wounded in action, triggering physical infirmities, which eventually forced him to retire from active service, at first temporarily, in 1809 and then permanently, in late 1813.

The Battle of Wagram was a military engagement of the Napoleonic Wars that ended in a costly but decisive victory for Emperor Napoleon's French and allied army against the Austrian army under the command of Archduke Charles of Austria-Teschen. The battle led to the breakup of the Fifth Coalition, the Austrian and British-led alliance against France. Wagram was the largest battle in European history up to its time.
