planned a double-envelopment that required a quick march from the forces of his brother John, who was a few kilometers east of the battlefield. Napoleon's plan envisaged an envelopment of the Austrian left with Davout's III Corps while the rest of the army pinned the Austrian forces. Klenau's VI Corps, supported by Kollowrat's III Corps, started the battle on the second day at 4 am with a crushing assault against the French left, forcing the latter to abandon both Aspern and Essling. Meanwhile, Bernadotte had unilaterally ordered his troops out of the central village of Aderklaa, citing heavy artillery shelling, and compromised the French position. Napoleon was livid and sent two divisions of Massena's corps supported by cavalry to regain the critical village. After difficult fighting in the first phase, Massena sent in Molitor's reserve division, which slowly captured Aderklaa back for the French, only to lose it again following fierce Austrian bombardments and counterattacks. To delay the Austrian army for Davout's materializing assault, Napoleon sent 4,000 cuirassiers under Nansouty against the Austrian lines. To dissuade the Austrians from attacking, Napoleon formed a 112-gun grand battery in the center of his lines. As Davout's men were progressing against the Austrian left, Napoleon formed the three small divisions of MacDonald into a hollow, oblong shape that marched against the Austrian center. The lumbering phalanx was devastated by Austrian artillery but managed to break through the Austrian forces. With the Austrians at Wagram weakened by the need to reinforce their left against Davout, Oudinot was able to capture the village and split the Austrian army. Upon learning that his brother's forces would not arrive until the evening, Charles ordered a withdrawal at 2.30 pm. The Austrians withdrew in good order, the main army westwards and the left-wing to the north. The French suffered heavy losses, around 32,000 men, with their commanders particularly affected as around 40 French generals were killed and wounded; Austrian losses stood at around 35,000. Fighting was renewed at Znaim on 10–11 July. On 12 July, Charles signed the Armistice of Znaim, which led to lengthy peace negotiations between Napoleon and Metternich.

The Austrians defended against several bungled French assaults at the Battle of Sacile in April, causing Eugène to fall back on Verona and the Adige River.
