notes=In the Battle of Aspern-Essling (21 May – 22 May, 1809), Napoleon attempted a forced crossing of the Danube near Vienna, but the French and their allies were driven back by the Austrians under Archduke Charles. The battle was the first time Napoleon had been personally defeated in over a decade.

Background

At the time of the battle Napoleon was in possession of Vienna, the bridges over the Danube had been broken, and the Archduke's army was near the Bisamberg, a mountain near Korneuburg, on the left bank of the river. The French wanted to cross the Danube. Lobau, one of the numerous islands which divide the river into minor channels, was selected as the point of crossing. Careful preparations were made, and on the night of the 19th-20th of May the French bridged all the channels on the right bank to Lobau and occupied the island. By the evening of the 20th many men had been collected there and the last arm of the Danube, between Lobau and the left bank, bridged. Masséna's corps at once crossed to the left bank and dodged the Austrian outposts. Undeterred by the news of heavy attacks on his rear from Tyrol and from Bohemia, Napoleon ferried all available troops to the bridges, and by daybreak on the 21st, 40,000 men were collected on the Marchfeld, the broad plain of the left bank, which was also to be the scene of the Battle of Wagram.

The Archduke did not resist the passage. It was his intention, as soon as a large enough force had crossed, to attack it before the rest of the French army could come to its assistance. Napoleon had accepted the risk of such an attack, but he sought at the same time to minimize it by summoning every available battalion to the scene. His forces on the Marchfeld were drawn up in front of the bridges facing north, with their left in the village of Aspern (Gross-Aspern) and their right in Essling (or Esslingen). Both places lay close to the Danube and could not therefore be turned; Aspern, indeed, is actually on the bank of one of the river channels. The French had to fill the gap between the villages, and also move forward to give room for the supporting units to form up.

Units led by Johann von Hiller, Heinrich Graf von Bellegarde and Franz Xavier Prince zu Hohenzollern-Hechingen were to converge upon Aspern, while Franz Fürst von Rosenberg-Orsini (Prince Rosenberg) was to attack Essling. The Austrian cavalry was in the center, ready to move out against any French cavalry attacking the heads of the columns. During the 21st the bridges became more and more unsafe, owing to the violence of the current, but the French crossed without intermission all day and during the night.

First Day

The battle began at Aspern; Hiller carried the village at the first rush, but Masséna recaptured it, and held his ground with the same tenacity as he had shown at Marengo. The French infantry fought with the old stubborn bravery which it had failed to show in the earlier battles of the war.

The three Austrian columns were unable to capture more than half the village. The post was still held by Masséna when night fell. Meanwhile, all the French infantry between the two villages and in front of the bridges had been drawn into the fight on the flank. Napoleon therefore, to create a diversion, sent forward his center, now consisting only of cavalry, to charge the enemy's artillery, which was deployed in a long line and firing on Aspern. The first charge of the French was repulsed, but second attempt was made by heavy masses of cuirassiers. The French horsemen drove off guns, rode round Hohenzollern's infantry squares, and resisted the cavalry of Lichtenstein, but they were unable to do more, and in the end they retired to their old position.

In the meanwhile Essling had been the scene of fighting almost as desperate as that of Aspern. The French cuirassiers made heavy charges on the flank of Rosenberg's force, and delayed an assault. In the villages, Lannes with a single division resisted until night ended the battle. The two armies bivouacked, and in Aspern the French and Austrians lay within pistol shot of each other. The emperor was not discouraged, and renewed efforts to bring up every available man. All through the night more and more French troops came across.

Second Day

At the earliest dawn of the 22nd the battle was resumed. Masséna swiftly cleared Aspern of the enemy, but at the same time Rosenberg stormed Essling. Lannes, however, resisted desperately, and reinforced by St Hilaire's division, drove Rosenberg out. In Aspern, Masséna was driven out by a counter-attack of Hiller and Bellegarde.

Meanwhile Napoleon had launched a great attack on the Austrian center. The whole of the French center, with Lannes on the left and the cavalry in reserve, moved forward. The Austrian line was broken through, between Rosenberg's right and Hohenzollern's left. Victory was almost won when the Archduke brought up his last reserve, leading his soldiers with a colour in his hand. Lannes was checked, and with his repulse the impetus of the attack died out all along the line. Aspern had been lost, and the news reached Napoleon at the critical moment. The Danube bridges, which had broken down once already, had been cut by heavy barges, which had been sent drifting down stream by the Austrians.

Napoleon at once suspended the attack. Essling now fell to another assault of Rosenberg, and the French drove him out again. Rosenberg then directed his efforts on the flank of the French center, slowly retiring on the edges. The retirement was terribly costly, but Lannes stopped the French from being driven into the Danube. Complete exhaustion of both sides ended the fighting.

Results

The French lost over 20,000 men including one of Napoleon's ablest field commanders and close friend, Marshal Jean Lannes, who died after being mortally wounded by an Austrian cannon ball. The Austrians had also suffered similar casualties but had secured the first major victory against the French for over a decade. The victory demonstrated how far the Austrian army had progressed since the string of catastrophic defeats in 1800 and 1805.

The French forces were withdrawn to the island, and on the night of the 22nd the last bridge was repaired, and the army awaited the arrival of reinforcements in Lobau. The Austrians failed to capitalise on the situation allowing the French to regroup. One month later, the French made a second attempt to cross the Danube and the two armies would meet again at Wagram.

Accounts

Patrick Rambaud, a French author, wrote a fictionalized account of the conflict entitled "The Battle." The novel provides a rather rare first-person description of combat in the Napoleonic era, as well as detailed depictions of famous commanders such as Napoleon, Massena, and Lannes. The concept and notes for the book originally came from noted French author Honoré de Balzac.

The army surgeon Dominique-Jean Larrey also described the battle in his memoirs and mentions how he fed the wounded at Lobau with a bouillon of horse meat seasoned with gunpowderParker, Harold T.
