Battle of Wagram
The Battle of Wagram ([ˈvaɡram]; 5–6 July 1809) was a military engagement of the Napoleonic Wars that ended in a costly but decisive victory for Emperor Napoleon's French and allied army against the Austrian army under the command of Archduke Charles of Austria-Teschen. The battle led to the breakup of the Fifth Coalition, the Austrian and British-led alliance against France. Wagram was the largest battle in European history up to its time.
In 1809, the French military presence in the Confederation of the Rhine was diminished as Napoleon transferred a number of soldiers to fight in the Peninsular War. As a result, the Austrian Empire saw its chance to recover some of its former sphere of influence and invaded the Kingdom of Bavaria, a French ally. Recovering from his initial surprise, Napoleon beat the Austrian forces and occupied Vienna at the beginning of May 1809. Despite the string of sharp defeats and the loss of the empire's capital, Archduke Charles salvaged an army, with which he retreated north of the Danube. This allowed the Austrians to continue the war. Towards the end of May, Napoleon resumed the offensive, suffering a surprise defeat at the Battle of Aspern-Essling.
It took Napoleon six weeks to prepare his next offensive, for which he amassed a 172,000-man French, German and Italian army in the vicinity of Vienna. The Battle of Wagram began after Napoleon crossed the Danube with the bulk of these forces during the night of 4 July and attacked the 136,000-man strong Austrian army. Having successfully crossed the river, Napoleon attempted an early breakthrough and launched a series of evening attacks against the Austrian army. The Austrians were thinly spread in a wide semicircle, but held a naturally strong position. After the attackers enjoyed some initial success, the defenders regained the upper hand and the attacks failed. Bolstered by his success, the next day at dawn Archduke Charles launched a series of attacks along the entire battle line, seeking to take the opposing army in a double envelopment. The offensive failed against the French right but nearly broke Napoleon's left. However, the Emperor countered by launching a cavalry charge, which temporarily halted the Austrian advance. He then redeployed IV Corps to stabilise his left, while setting up a grand battery, which pounded the Austrian right and centre. The tide of battle turned and the Emperor launched an offensive along the entire line, while Maréchal Louis-Nicolas Davout drove an offensive, which turned the Austrian left, and rendered Charles's position untenable. Towards mid-afternoon on 6 July, Charles admitted defeat and led a retreat, frustrating enemy attempts to pursue. After the battle, Charles remained in command of a cohesive force and decided to retreat to Bohemia. However, the Grande Armée eventually caught up with him and scored a victory at the Battle of Znaim. With the battle still raging, Charles decided to ask for an armistice, effectively ending the war.
With 74,000 casualties, the two-day battle of Wagram was particularly bloody, mainly due to the use of 800 artillery pieces and the expenditure of 200,000 rounds of artillery ammunition on a flat battlefield packed with some 300,000 men. Although Napoleon was the uncontested winner, he failed to secure an overwhelming victory and the Austrian casualties were only slightly greater than those of the French and allies. Nonetheless, the defeat was serious enough to shatter the morale of the Austrians, who could no longer find the will to continue the struggle. The resulting Treaty of Schönbrunn meant the loss of one sixth of the Austrian Empire's subjects, along with some territories, rendering it landlocked until the German Campaign of 1813.
After the battle, Emperor Napoleon bestowed on Louis-Alexandre Berthier, who was his Marshal, Chief of Staff, Minister of War and Vice-Constable of the Empire, the victory title of 1st Prince of Wagram, making him an official member of the French nobility. Berthier had previously been granted the title of Sovereign Prince of Neuchâtel and the Prince of Valangin in 1806. This allowed his descendants to carry the titles of Prince and Princess of Wagram.
The second day[edit]
Rosenberg's attack[edit]
Positioned on the left of the Austrian army, in and around the strategic village of Markgrafneusiedl, Feldmarschalleutnant Prince Rosenberg-Orsini was in command of the 18,140 men and 60 cannons of the IV Korps. In addition, attached to his force was the much-battered Advance Guard, under Feldmarschalleutnant Nordmann, reduced to around 6,000 infantrymen and some cavalry support,[Note 6] as well as the 3,120 cavalrymen from Feldmarschalleutnant Nostitz's division.[77] Receiving his orders in due time, Rosenberg began to organise his attack, forming the IV Korps into three large columns, preceded by an advance guard. The first column was formed by Hessen-Homburg's brigade, 6 battalions strong, which was directed towards the village of Grosshofen. The second column was 16 battalions strong (12 regular and four Landwehr battalions) and included the brigades of Swinburn and Weiss, with the orders to move on to Glinzendorf. The second column was preceded by an advance guard under Feldmarschalleutnant Radetzky, 10 battalions and 10 cavalry squadrons strong. The third column, under Nostitz, was 30 squadrons strong and was directed to outflank the French, towards Leopoldsdorf. Setting these troops in motion towards 4:00, just as his orders stated, Rosenberg instructed his commanders to maintain absolute silence among the rank and file as they advanced but, despite this, the troops moved forward in some disorder and with a lot of noise.[78][79]
Aftermath[edit]
Pursuit and armistice[edit]
By nightfall on 6 July, the Austrians, still capable of action, had broken contact with their pursuers and Charles had managed to reestablish a cohesive, albeit irregular front. The remarkable combat-worthiness shown during the evening fighting left Napoleon wondering whether the Austrians would actually renew battle the next day. The Emperor rose early on 7 July and reconnoitred the battlefield in person, noting the huge losses in men on both sides and seeing that the Austrians had withdrawn. He then returned to more practical matters and, after receiving MacDonald's report, he suddenly embraced the general and elevated him to the dignity of Maréchal d'Empire, the only Marshal to receive the title on a field of battle. The Emperor also criticised Marmont for his slowness in arriving on the battlefield and told Oudinot that he ought to have him shot for attacking without orders. The French resumed their pursuit towards 14:00, as the extreme exhaustion of the army prevented an early start. Their artillery had fired somewhere between 90,000 and 100,000 rounds during the battle, which left the caissons empty and it took some time before they could be refilled.[142] Among the rank and file, there were even instances of severe breakdown in troop discipline, as the army moved through county packed with vines and wine cellars. When an incensed Oudinot, sabre in hand, tried to restore discipline among a group of drunken cavalrymen from his army corps, he was almost attacked by his own men.[143] Pursuit was further complicated by the absence of reliable information about the exact direction of the Austrian retreat. Contradictory intelligence collected by the various Corps confusingly stated that the Austrians were retreating either towards to Brünn or to Znaim and other reports were actually indicating a retreat towards Moravia. The French tried to close the gap through sustained march. Spearheading the pursuit were the army corps of Masséna to the west, Marmont in the centre and Davout to the east, while the "Army of Italy" was detailed to keep an eye on Archduke John's army.[144][145]
The Austrians were actually retreating towards Znaim in Bohemia. The Austrian army had suffered greatly during the Battle of Wagram and had to leave behind their wounded, but did make off with thousands of French prisoners, a couple of dozen guns and a few eagles. Making good use of night marches, Archduke Charles had the bulk of his forces assembled at Korneuburg on 7 July.[146] Charles and his senior commanders had considered various plans to continue the campaign, but in the end, Charles was not positioning his army for a continuation of the campaign. The Austrian commander's view well before the Battle of Wagram had been that Austria's best option was to make peace and, in order to achieve that, the Empire needed to have a large, battle-worthy army, which they could use as leverage during the peace talks. Between 9 and 12 July, the French from Eugène's "Army of Italy" clashed with Archduke John's forces in a series of skirmishes and pushed them back into Hungary, while Masséna caught up with and fought the Austrian rearguard in several actions, most notable of which was the one at Hollabrunn. By now, Napoleon had largely understood Charles's intentions and manoeuvred against them. Marmont and his small XI Corps was the first to engage the Austrian army at the Battle of Znaim and was momentarily largely outnumbered. His 10,000 men faced some 60,000 massed enemy troops, but, in the typical style of Napoleonic warfare, Marmont decided to attack in order to pin down the enemy. He could reasonably expect to be reinforced soon and at 22:00, Napoleon arrived with reinforcements. The battle raged on the next day, with some bloody fighting going on around Znaim. The Austrians took heavy casualties, some 6,200 men, during the battle and, as time passed, the French force was set to be augmented to some 84,000 men, following the imminent arrival of Davout and Oudinot. Recognising the futility of another battle, Charles decided to ask for an armistice. He did so on his own responsibility, as he did not have permission to do so from Emperor Francis I. Ignoring the advice of his senior commanders – Maréchal Berthier was vocal in advising the continuation of hostilities and destruction of the Austrian Empire – Napoleon accepted. The Armistice of Znaim marked the end of the active phase of the 1809 war between France and Austria.[147][148][149]
Casualties[edit]
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.[150][151]
Napoleon used his usual propaganda to minimise his losses, stating in the Bulletin of the Grande Armée that Wagram cost the army only "1,500 dead and 3,000 to 4,000 wounded". In reality, losses had been horrendous.[152] French medical services were completely overwhelmed, although imperial guardsmen were given priority and were quite well cared for. Of the total 1,200 guardsmen of all arms wounded at Wagram, half were able to return to the ranks within a few days and only 145 died from their wounds. The troops of the line were not so lucky. Most of the wounded on both sides had been hit by cannon fire, which caused horrendous injuries, often requiring amputation. The shock of the surgery, massive loss of blood, poor after-care and the risk of infection meant the chances of survival following amputation were not good.[153]
Globally, since neither army provided a complete tabulation of their losses, the exact number of casualties is hard to establish. One author suggests that French casualties of all sorts approached 40,000 men, greatly surpassing those of the Austrians.[72] More conservative estimates place overall French losses at between 25,000 or 28,000 men[154] and either 31,500[150] or 33,000 men. Five generals (Duprat, Gautier, Guiot de Lacour, Lasalle and von Hartitzsch)[155] and another 238 officers, as well as 7,000 men were killed. Additionally, 37 generals, 883 officers and over 25,000 men were wounded and 4,000 men were taken prisoner, many of them wounded.[150][Note 10]
On the Austrian side, losses had also been heavy. An official tabulation established that there were 51,626 officers and men missing on 11 July 1809, compared to the overall complements on 5 July 1809. This figure thus accounts not only for the Battle of Wagram, but also for losses during the many minor engagements and skirmishes that took place after the battle, as well as the losses suffered during the Battle of Znaim.[150] Many of these men were simply missing in action and were subsequently able to return to the colours. Nevertheless, conservative estimates of the Austrian losses at Wagram numbered some 30,000 men, of whom 24,000 were killed or wounded, and the rest taken prisoner.[72] According to Ian Castle, Austrian casualties were as follows: 41,250 total, of which 23,750 killed or wounded, 10,000 missing, 7,500 captured, while French and Allied casualties amounted to 37,500, with 27,500 killed or wounded and 10,000 missing or captured.[156] Four Austrian generals were killed or mortally wounded during the fighting: Nordmann, Vukassovich, Vécsey, and d'Aspré.[157]
Analysis[edit]
Just as in the bloody Battle of Eylau, Wagram was a battle in which Napoleon failed to score an uncontested victory with relatively few casualties. The French forces suffered 34,000 casualties, a number compounded by the 20,000 suffered only weeks earlier at Aspern-Essling. This would be indicative both of the lack of continued growth in experience of Napoleon's troops and the increasing experience and competence of his opponents, who were learning from previous errors. The heavy losses suffered, which included many seasoned troops as well as over thirty generals of varying rank, was something that the French would not be able to recover from with ease. Bernadotte's dismissal from the Grande Armée for his failure would have severe consequences for Napoleon in later years. Unexpectedly elected heir to the throne of Sweden the following year, the former Marshal would eventually prove an asset to the Sixth and Seventh Coalition.
