The Battle of Ebelsberg, known in French accounts as the Battle of Ebersberg, was fought on 3 May 1809 during the War of the Fifth Coalition, part of the Napoleonic Wars. The Austrian left wing under the command of Johann von Hiller took up positions at Ebersberg on the Traun river. The French under André Masséna attacked, crossing a heavily defended 550-meter-long bridge and subsequently conquering the local castle, thus forcing Hiller to withdraw. Ebelsberg is now a southern suburb of Linz, situated on the south bank of the Traun, a short distance above the place where that stream flows into the Danube River.
Separated from the main Austrian army by the battles of Abensberg and Landshut, Feldmarschall-Leutnant Hiller retreated east to Linz by 2 May with the three left wing corps. The Austrians hoped to slow the French advance towards Vienna. The leading elements of Marshal Masséna's corps overran Hiller's rear guard on the west bank of the Traun on the morning of 3 May. In the rout that followed, the first French infantry brigade rushed the bridge and got into the streets of Ebelsberg. At this point, the Austrians began to fight back effectively.
To keep from being thrown into the river, the French committed an entire division to the street fight, in which the Ebelsberg castle loomed as the key position. After Masséna threw in a second division, the French finally ejected the Austrians from the castle. Unwilling to recapture the town, Hiller ordered his artillery to set fire to the place. In the blaze that followed, hundreds of wounded soldiers from both armies died. The battle and the heavy casualties were unnecessary because Hiller was already flanked out of position by a second French corps that crossed the Traun upstream.
Background On 10 April 1809, the Austrian army of Archduke Charles, Duke of Teschen invaded the Kingdom of Bavaria, an ally of Napoleon. During the first week of war, Napoleon's deputy, Marshal Louis Alexandre Berthier, mismanaged the deployment of the Franco-German army. Nevertheless, the archduke was unable to take advantage of his opportunities because of the slow marching speed of his troops. Napoleon soon arrived on the scene and, in the first major clash on 19 April, Marshal Louis Davout won the hard-fought Battle of Teugen-Hausen. Thanks to his victory, Davout was able to link up with the main body of Napoleon's army near Abensberg that evening.
At the Battle of Abensberg on 20 April, Hiller arrived from the south to take command of Feldmarschall-Leutnant Archduke Louis of Austria's V Armeekorps and Feldmarschall-Leutnant Michael von Kienmayer's II Reserve Armeekorps, in addition to his own VI Armeekorps. Before the battle, Hiller's strength had been weakened by the detaching of Feldmarschall-Leutnant Karl Friedrich von Lindenau's division from V Armeekorps and General-Major Andreas Schneller's cuirassier brigade from II Reserve Armeekorps to the main army, Andreas Schneller's brigade, plus Feldmarschall-Leutnant Franz Jellacic's division from VI Armeekorps to hold Munich. At Abensberg and at the Battle of Landshut on 21 April, Napoleon's army roughly handled Hiller's command and forced the Austrian to withdraw to the southeast, away from Archduke Charles and the main army. Between 19 and 21 April, Hiller lost 12,140 soldiers, 11 guns, and 328 wagons from V and VI Armeekorps. His wing shrank from 42,000 troops to around 27,000 to 28,000 by the evening of 22 April.
On 22 April, Napoleon marched north with major forces to defeat Archduke Charles at the Battle of Eckmühl. Unaware that the main army had retreated north of the Danube River, Hiller turned to face a weak pursuit force. He inflicted a sharp check on Marshal Jean-Baptiste Bessières at the Battle of Neumarkt-Sankt Veit on 24 April. Apprised of the fact that Charles had been defeated, the Austrian wing commander quickly pulled back to the southeast. On 24 April Charles sent a message to Hiller ordering him to retreat to Linz, cross to the Danube's north bank, and join the main army. Hoping to overtake and destroy Hiller, Napoleon sent two columns after his foe. The emperor directed Marshal Louis Davout's III Corps, Masséna's IV Corps, and General of Division Dominique Vandamme's VIII Corps along a northern route via Passau on the Inn River. The II Corps of Marshal Jean Lannes and Bessières' force took a more southerly route through Burghausen on the Salzach River.
On 26 April, General of Division Claude Juste Alexandre Legrand of Masséna's IV Corps clashed with Hiller's rear guard, led by Feldmarschall-Leutnant Josef von Dedovich, at Schärding and seized the bridge over the Inn. That same day, another of Masséna's divisions occupied Passau, capturing 400 Austrians. Meanwhile, Hiller was enjoying his independence from Archduke Charles, who was far away in Bohemia. Also, he was in easy communication with Emperor Francis I of Austria, who wished to exert his influence on the campaign. Encouraged, Hiller came up with a plan to counterattack Masséna on 27 April and ordered Feldmarschall-Leutnant Emmanuel von Schustekh-Herve to implement it. Nothing came of this scheme, and the Austrian retreat continued toward Linz.
On 1 May, Legrand and 1,400 troops caught up with Schustekh's 850-man rear guard between Riedau and Kallham. The Dragoon Regiment of the Grand Duchy of Baden charged the 3rd battalion of the Jordis Infantry Regiment # 59, which was drawn up in square. Waiting until the foot soldiers fired a volley, the dragoons then charged and broke into the square. After their commander, Oberstleutnant Beck, was cut down, 706 officers and men of the Jordis battalion laid down their weapons. Two squadrons of the Kienmayer Hussar Regiment # 8 suffered 10 killed, 50 wounded, and 23 captured. The Badeners reported losing only three killed and 10 wounded, though a large number of their horses were killed. There was a clash between General of Division Claude Carra Saint-Cyr's vanguard and General-Major Frederick Bianchi, Duke of Casalanza on 2 May at Räffelding, three kilometers southeast of Eferding. The Baden Dragoons lost 14 casualties, while Austrian losses were unreported.
After abandoning Regensburg, Archduke Charles first retreated to Cham on the border of Bohemia, where he reorganized his army. From there he marched for České Budějovice (Budweis). Fearing Napoleon might follow him into Bohemia, Charles wrote to Archduke John of Austria on 3 May that he planned to fight at Budweis. As late as 6 May, the main army remained in the vicinity of that city. However, detachments under Feldmarschall-Leutnant Johann von Klenau and General-Major Karl Wilhelm von Stutterheim operated closer to Linz on the north side of the Danube.
On the night of 2 May, Emperor Francis left Linz, crossed the Danube, and hastened to join the army of his brother Charles. He left instructions for Hiller to delay Napoleon's advance by taking up positions behind the Traun at Ebelsberg and Lambach. If this failed, Hiller could defend the line of the Enns River farther east. Hiller posted General-Major Armand von Nordmann's 3,000-man brigade near Lambach to guard his south flank. Francis appointed his brother-in-law Archduke Maximilian of Austria-Este to command Vienna, but most of the garrison was poorly trained.
On 2 May, Marshal François Joseph Lefebvre's Bavarian VII Corps reported sparring with Jellacic at Golling an der Salzach south of Salzburg. Bessières with his cavalry and Lannes with General of Division Nicolas Oudinot's II Corps infantry division reached Wels on the Traun to find the bridge burned. Generals of Division Louis Vincent Le Blond de Saint-Hilaire (III Corps), Gabriel Jean Joseph Molitor (IV Corps), and Joseph Laurent Demont (III Corps) were nearby with their divisions, and Napoleon arrived at Lambach. Vandamme's Württemberg VIII Corps marched in the vicinity of Riedau. Davout's III Corps was due to arrive in Passau on 3 May, while Napoleon ordered General of Division Marie François Rouyer to leave Regensburg and march to Passau. The 12,000-man Imperial Guard under General of Division Frédéric Henri Walther reached the vicinity of Braunau am Inn at the beginning of May.
Battle
Rear guard action
Early on 3 May, General of Brigade Jacob François Marulaz set out from near Eferding with Masséna's IV Corps cavalry division. Following the mounted troopers, in order, were the infantry divisions of Generals of Division Michel Marie Claparède (on loan from II Corps), Claude Legrand, Carra Saint-Cyr, and Jean Boudet. The French cavalry ran into a small infantry ambush at Wilhering, which is on the Danube about halfway from Alkoven and Linz. At 9:00 AM, the column marched into Linz and took the road south toward Ebelsberg.
At 3:00 AM, Hiller put his soldiers on the road. He directed Kienmayer's small II Reserve Armeekorps to lead the march, while the main bodies of the V and VI Armeekorps followed. That morning, the Austrian wing commander deployed four of his eight brigades as rear guards under Bianchi, Schustekh, General-Major Josef Radetzky, and Feldmarschall-Leutnant Karl von Vincent. As the Austrian wagon train filed across the bridge at Ebelsberg, Hiller's staff lost control of the situation, the drivers panicked, and the roadway became jammed with retreating vehicles and troops. Eventually, the mob of troops and wagons squeezed across the span and even Bianchi was across the Traun by 9:00 AM with the Duka Infantry Regiment # 39 and Ignaz Gyulai Infantry Regiment # 60.
However, Schustekh was still somewhere to the southwest so Vincent and Radetzky drew up their forces on the west bank and waited for their colleague to make his appearance. Vincent had the Benjowsky Infantry Regiment # 31 and Splenyi Infantry Regiment # 51 of General-Major Josef Hoffmeister's brigade under his orders. He placed one battalion in the village of Klein München and the other five between there and Scharlinz. He screened the infantry with the Rosenberg Chevau-léger Regiment # 6. Radetzky, with two battalions and six squadrons, deployed on Vincent's left, watching for Schustekh. Radetzky's brigade included the Gradiskaner Grenz Infantry Regiment # 8, Merveldt Uhlan Regiment # 1, and Archduke Charles Uhlan Regiment # 3. Smith gives Radetzky 16 squadrons, while Petre counts only six.
Schustekh finally appeared with the Kienmayer Hussar Regiment # 8 and General-Major Otto von Hohenfeld's brigade, the Klebeck Infantry Regiment # 14 and Jordis Infantry Regiment # 59 and began crossing the bridge. At about 10 AM, Marulaz's troopers came under fire from the woods north of Scharlinz. While waiting for infantry support, he drew up the French 3rd, 14th, 19th, and 23rd Chasseurs à cheval in the first line, the Baden Light Dragoons, Grand Duchy of Hesse Garde Chevau-léger, and Württemberg Chevau-léger Regiments in the second line. Soon, General of Brigade Louis-Jacques Coëhorn's troops appeared and, at Masséna's personal command, attacked Klein München with the bayonet. Coëhorn's brigade included the 4th battalions of the 17th, 21st, 26th, and 28th Light Infantry Regiments, the Tirailleurs du Po, and the Tirailleurs Corses.
By this time the Rosenberg Chevau-légers had withdrawn across the bridge at Vincent's orders. The Austrian defenders of the village put up a poor fight and Coëhorn's men drove them from their positions. From the direction of Wels, Bessières showed up with General of Brigade Hippolyte Piré's brigade, a hussar and a chasseurs à cheval regiment, and attacked Radetzky who covered Schustekh's retreat. Radetzky put up a gallant resistance, for which he later earned the Commander's Cross of the Military Order of Maria Theresa. Meanwhile, Hoffmeister made a stand behind the millstream on the west bank. His efforts were futile as French infantry and cavalry charged forward. Seeing that the situation was critical, Vincent ordered a retreat and soon the Austrians were stampeding across the bridge in panic.
