In 1809 the world's undisputed military genius - Napoleon Bonaparte - confronted his implacable continental foe, the Hapsburg Empire. During the Vienna campaign of that year, Napoleon suffered his first defeat since becoming Emperor, but rebounded to win Wagram, a battle of unprecedented lethality.

The sun rose on April 24, 1809, to illuminate a continent at war. From Poland to Spain, some 600,000 soldiers awakened to duty. Nowhere was the concentration of forces greater than in the Danube Valley where Napoleon had determined to launch his blow against the Austrian Generalissimus Erzherzog (Archduke) Karl. If Karl triumphed, most of Europe stood poised to pounce, Napoleon and the French Empire would be attacked from all quarters.

If Karl failed, all Europe - except England and perhaps Portugal and Spain - would make whatever accommodations were necessary to survive under Napoleonic hegemony.

The ensuing campaign led to Napoleon's first defeat at Aspern-Essling. So, at the end of May, Napoleon sat with his battered army at the end of a long and imperiled line of communications while Europe erupted around him. Yet, at the moment of supreme crisis, Napoleon displayed his formidable talents and prepared a masterful counterstroke. French and Austrian alike suffered horrific losses at Wagram, but at battle's end, Napoleon's commanding presence produced a French triumph.

It was a victory so complete that the Emperor forced Austria into an unwilling alliance and even took the daughter of the Austrian Kaiser to be his new wife. For one last time, the French conqueror redrew Europe's map.
