Wagram (Campaign of Wagram).

Fought July 6, 1809, between 150,000 French, under Napoleon, and 140,000 Austrians, under the Archduke Charles. Napoleon crossed the lesser arm of the Danube from the Island of Lobau, on the night of the 4th and 5th July, and driving the Austrian advanced posts before him, prepared to attack their main position. An attack upon them on the evening of the 5th was repulsed. On the 6th the Austrians attacked the French right, under Davoust, but were unsuccessful; later, however, the French centre and left were compelled to give ground, but Napoleon bringing up the artillery of the Guard and Macdonald's corps, checked the Austrian advance, while Davoust carried the heights on the Austrian left, outflanking them, and rendering their position untenable. By three o'clock they were in full retreat, having lost about 24,000 killed and wounded, 9,000 prisoners, including 12 generals, and 20 guns. The French lost 18,000 killed and wounded.
