Casualties With more than 300,000 combatants, Wagram was the largest battle in European history up to its time. With at least 72,000 casualties on both sides, it was also the bloodiest military engagement of the entire Revolutionary and Napoleonic Wars thus far. The unusually high casualty rate was due mainly to an unprecedented concentration of artillery, on a flat battlefield, where the deadly roundshot – each army fired at least 90,000 during the two days of battle – was most effective.
