The Battle of Vízakna was a battle in the Hungarian war of Independence of 1848-1849 fought on 4 February 1849 between the Hungarian army led by the Polish General Józef Bem and the Austrian army of the Habsburg Commander-in-Chief of Transylvania, Lieutenant General Anton Puchner. The Hungarian national poet Sándor Petőfi participated in the battle in the Hungarian army, then wrote a poem entitled Négy nap dörgött az ágyú (Four days the cannons roared...) in which he described the battle. The Austrian forces, who had a significant numerical superiority, were victorious, almost entirely destroying the Hungarian army. Unfortunately after the battle many Hungarian soldiers who could not retreat with the troops, or remained wounded on the battlefield, were killed by the Austrians and their Romanian militia allies, as an act of war crime. With this defeat, all of Bem's previously gained achievements were put in jeopardy, but Bem's skillful operations in the following weeks turned the struggle for Transylvania back in his favour.Tarján M.

Background After the Hungarian armies were driven out of Transylvania in October–November 1848, an important turning point in the Hungarian War of Independence was the appointment of the Polish Józef Bem as a general of the Hungarian army of Transylvania, as he launched an unexpected attack against the Austrian and Romanian troops advancing towards the Hungarian Plain, trying to attack from the east Hungary, which was attacked at the same time by the Austrian main army of Field Marshal Alfred I, Prince of Windisch-Grätz from the West, Lieutenant General Franz Schlik from the North and the Serbian insurgents from the South in December 1848. With his characteristic steadfastness and speed, Bem cut the imperial front in two on 23 December near Dés, first driving Colonel Karl von Urban's border guard regiments into Bukovina and then turning south to win a decisive victory over Lieutenant General Anton Puchner, the main commander of the Austrian armies from Transylvania. In January 1849, the Honvéd Army liberated Székely Land, and then defeated Puchner, who was in an increasingly desperate situation, near Szőkefalva. The imperial commander-in-chief was forced back to his headquarters in Nagyszeben, but Bem tried unsuccessfully to take the city on 21 January in the First Battle of Nagyszeben. This was Bem's first defeat in Transylvania.

After his victory at Nagyszeben, Puchner launched an attack, but Bem defeated him in the Battle of Szelindek on 24 January, and forced him to retreat back to where he came from. After this successful battle, Bem sent Major Farkas Kemény with the 11th and 55th Battalions, 1 company of the Mátyás Hussars and a six-pounder battery to Déva via Vízakna-Szerdahely-Szászsebes and Szászváros, to wait there for the relief troops sent from Hungary then return in quick marches, or to wait at Déva for Bem along the Transylvanian-Hungarian border in the case if he was forced to retreat by Puchner. Bem retreated from the vicinity of Nagyszeben to Vízakna with Kemény, the latter continuing his way with his detachment towards Déva. After the defeat at Szelindek, Puchner no longer had confidence that he could deliver a decisive blow to Bem with the forces at his disposal, and so, since the Austrian Minister of War could not send reinforcements, he looked in another direction to obtain relief troops.Bánlaky József: A Vízaknai csata (1849. február 4-én). A magyar nemzet hadtörténete XXI Arcanum Adatbázis Kft. 2001 Nicholas I of Russia, had already sent a corps to Moldavia and Wallachia in 1848 under the command of General Alexander von Lüders to contain the revolutionary movements there, which, in view of the events in Transylvania and Hungary, was left in the said provinces for the duration of the Hungarian War of Independence. Puchner intended to use the intervention of this foreign force, but to make things look less compromising for the Habsburg empire, the letter of invitation was written not in his name, as a general of the Austrian army, but on behalf of the Transylvanian Saxons and Romanians. Lüders, however, only offered to intervene on behalf of his government on condition that the commander of the Habsburg troops formally requested it, which Puchner did by decision of the council of war he had convened. The Russians, of course, were happy to help - in fact, Nicholas I (r. 1825–1855) first wanted to send an intervention army of 20,000 troops to Transylvania - but to avoid international complications, the Tsarist forces only invaded Brassó and Nagyszeben. As a result, on February 2, 3 and 4, Russian General Nikolai Engelhardt marched to Brassó with 2,680 infantry, 430 Uhlans, 190 Cossacks and 8 guns; and on February 4, Colonel Grigory Skariatin entered Nagyszeben with 1,960 infantry, 120 Cossacks and 6 guns.

Prelude As soon as the Russian troops were certain to enter Transylvania, Puchner decided to attack Bem with all the imperial troops at his disposal, and to this end, he assembled his forces in the night of February 3 to 4 in the suburbs of Nagyszeben, from where he began the advance at dawn. To carry the attack through, Puchner's corps was grouped as follows:

- Right wing brigade: Leader: Major Karl Riebel

1 infantry battalion; 2 platoons of dragoons; 1/2 three-pounder battery. Total: 800 infantry, 40 cavalry, and 3 cannons.

- Center brigade: Leader: Colonel Baron Johann Nepomuk Franz Joseph Karl Leopold Freiherr von Stutterheim

3rd Battalion of the Sivkovich Infantry Regiment; 1st Landwehr battalion of the Sivkovich Infantry Regiment; 1st battalion of the Bianchi Infantry Regiment; 3rd Battalion of the Charles Ferdinand Infantry Regiment; 1 Székely-Hussar company; a six-pounder infantry battery; 1/2 three-pounder infantry battery. Total: 2,223 infantry, 86 cavalry, and 15 cannons.

- Left wing brigade: Leader: General Joseph Freiherr von Kalliány

2 companies of the Saxon Kaiserjäger Battalion; Combined Battalion of the Charles Ferdinand Regiment; 1st Battalion of the Bianchi Regiment; 1st Battalion of the 1st Romanian Border Guard Regiment; 1 squadron of chevau-légers; 1 three-pounder 1/2 battery; Total: 1895 infantry, 72 cavalry, and 3 cannons.

- Cavalry brigade: Leader: Colonel Ludwig Losy von Losenau

6 cuirassier companies; a three-pounder 1/2 battery. Total: 424 cavalry, and 3 cannons.

- Reserve brigade: Leader: General Johann von Coppet

3d Battalion of the Parma Infantry Regiment; 3d Battalion of the Leiningen Infantry Regiment; 3d Battalion of the Tursky Infantry Regiment; Urraca Grenadier Battalion; 1 squadron of dragoons; 1 twelve-pounder cannons battery. Total: 2,439 infantry, 160 cavalry, and 6 cannons.

Corps total: 7,357 infantry, 782 horsemen, and 30 cannons, not counting the thousands of Romanian and Saxon militias.

Karl Riebel's right wing column had been sent forward in the early hours of the morning of 4 February on the old road to Torda, from which it was to turn off towards the north-eastern exit of Vízakna, sending out patrols towards Szelindek. The remainder of the corps did not depart until 6 a.m. The Center column of Stutterheim advanced on the Nagyenyed road, took position to fight in the center and with Riebel's column secured the connection with the 3rd battalion of the Sivkovich regiment. The left wing column of Kalliány advanced on the main road on the same line with the Stutterheim brigade, while the reserve column of Coppet followed by the Kalliány Brigade. Losenau's cavalry brigade was advancing on the back road west of the main road, was posted behind the left flank during the battle, to be used later as a separate cavalry brigade if required. Finally, a very considerable number of Romanian insurgents (probably several thousand), in order to secure the left flank of the corps, occupied the abatis between Orlát and Sibiel in the upper Cibin valley. A source, probable including also the number of the Romanian insurgents, shows Puchner's army as being 12,000 combatants and 42 (45) guns.Szentkatolnai Bakk Endre: Az 1848-49-iki szabadságharcz alatti események Vizaknán Budapest, 1880, pp. 142

Bem, after he unnecessarily sent away Kemény's brigade, had only 3 battalions, the same number of cavalry companies and 4 batteries left, and their number was according to János Czetz, as it follows:

4th Honvéd battalion: 800 men; Kemény's battalion: 600 men; 4 companies of the 31st Honvéd battalion: 500 men; Vienna legion: 30 men; a squadron of Matthias Hussars: 200 horsemen; a company of Wilhelm Hussars: 100 horsemen; a division of the Kress Cuirassiers: 75 horsemen; 24 cannons. In total: 1,930 infantry, 375 horsemen and 24 guns.

With this handful of troops, Bem intended to hold out against Puchner until the reinforcements arrived at Vízakna, where his troops built strong entrenchments. For a while Bem hoped that troops would arrive from Székely land to reinforce his troops, but the brigade from the Csíkszék and Háromszék seats which departed to help Bem, encountered a detachment of Russian troops which were sent from Brassó, which forced the leader of the Székely land army, Colonel Sándor Gál, to order his troops back, fearing that the unprotected Háromszék would be attacked by Russian and Austrian troops..

So Bem's small army, who was waiting for the Székelys in vain, built their positions in the abandoned salt mines around Vízakna.
