Serbian revolt (Summer 1848) In spring 1848, Serbian assemblies demanded national recognition and an end to feudalism. Kossuth rejected these, declaring Hungary a single political nation. Serbs formed the Main Committee at
Karlóca and began armed resistance, supported by Serbia and Austria. The uprising began on June 12 with the Hungarian
attack on Karlóca, but lacking enough forces the Hungarians were forced to retreat. Serb reinforcements soon turned the tide, capturing much of Southern
Bánát and
Bácska. Negotiations failed. When the Hungarians counterattacked and tried to capture the Serbian stronghold of
Szenttamás, it held out despite two sieges. Hungary achieved its first notable victory in the
Battle of Perlasz on September 2.
Autumn Campaign Military organization After the Batthyány government's fall in September, the National Defense Commission (OHB), led by Kossuth, took over. Recruitment accelerated; by December, 62 infantry battalions existed, some converted from earlier volunteer units. Due to officer shortages, the OHB promoted former
K.u.K. officers and trained civilians.
Operations in the main theater of war On September 11,
Ban of Croatia Josip Jelačić invaded Hungary with 50,000 troops. On October 7, Hungarian troops and militias led by the Colonels
Artúr Görgei and
Mór Perczel forced a 9000 strong Croatian corps to
Surrender at Ozora. Meanwhile, the Hungarian forces followed Jelačić to the Austrian border. The
Vienna Uprising began on October 6, forcing the emperor to flee the city. However, the Hungarian commanders hesitated to intervene and help the rebels against the imperial army, which was led by Field Marshal
Alfred I, Prince of Windisch-Grätz. Hungary retained
Komárom and others west of the
Tisza River, while the east mostly remained imperial. A rebellion began with covert support from General Anton Puchner, who openly turned against the Hungarian government on 18 October, citing the royal manifesto. Launching his offensive from the
Saxon regions of Transylvania, Puchner’s Austrian forces supported by the Romanian insurgents, quickly overwhelmed the Hungarian militias. The pro-Hungarian
Székelys resisted but, after initial successes, they were defeated in the
Battle of Marosvásárhely on 5 November, because of a lack of guns. Finally, the last Hungarian forces near
Kolozsvár collapsed, and their final effort ended with defeat at the
First Battle of Dés on 25 November, placing Transylvania under Austrian control. Despite being outnumbered, the Hungarians triumphed in the Battle of Törökbecse–Óbecse–Nagykikinda. Peace talks failed in late November, and no major fighting occurred in Bácska by year’s end.
Winter Campaign General situation and balance of power In December 1848, Austria sought to restore absolutism. Ferdinand V was replaced by Franz Joseph I, beginning efforts to revoke Hungary’s autonomy. Field Marshal Windisch-Grätz massed Austrian forces around Vienna, supported by Serbian, Transylvanian, and Croatian troops, totaling nearly 150,000 men and 350 guns. Hungarian forces, led by General Artúr Görgei, held key fortresses like Komárom and Pétervárad.
Main theater of war – Western Front On December 14, Austrian forces led by Windisch-Grätz crossed into Hungary. After capturing Pozsony and
Győr with little resistance, they defeated Perczel at the
Battle of Mór (December 30). The Hungarian government evacuated Pest for Debrecen. Hungarian forces launched a limited counterattack in January, retaking Szolnok and defeating Austrian units in the
Battle of Cegléd. Local leaders, including
Áron Gábor, organized resistance, producing cannons and defeating imperial forces in several clashes in December 1848. However, they were defeated at the
Battle of Hídvég on December 24. But the resistance of the small Háromszék diverted important Austrian troops from Western Transylvania, where they were mostly needed. By December 1848, Austrian General Puchner had taken control of Transylvania, except for Háromszék. Polish General
Józef Bem took command and, with 12,500 troops, launched a rapid counteroffensive. This enabled Puchner to attack the diminished Hungarian troops with all his forces.
Retreat from southern Hungary In December, Hungary launched an offensive against Serbian rebels, winning in the
Battle of Jarkovác and capturing several camps, but failing to retake Arad. A major defeat in the
Battle of Pancsova (Jan 2) led to General
Ernő Kiss’s dismissal and Damjanich taking command. By mid-January, Hungarian forces retreated north of the
Maros River, and imperial troops occupied Bácska, Bánát, and South
Transdanubia. In February, Serbs attacked
Szeged, but were repelled at the
Battle of Újszeged.
Hungarian counteroffensive under Dembiński Kossuth appointed
Henryk Dembiński as commander-in-chief on January 29. A day after Kápolna, in the
Battle of Mezőkövesd, the Hungarians repelled the pursuing Austrian cavalry, and on March 5, the troops of
János Damjanich and
Károly Vécsey won the
Second Battle of Szolnok, shattering Windisch-Grätz's hopes in a quick final victory. Görgei aimed to surround and defeat the enemy near
Gödöllő. Overall, Hungary had 101,000 soldiers and 624 guns. Windisch-Grätz, unaware of Hungarian movements, abandoned the Debrecen offensive and concentrated forces around Pest—55,000 troops and 220 cannons. were stationed in Transylvania and southern Hungary, totaling 115,000 troops, without counting the tens of thousands of Romanian militias.
Liberation of Transylvania and Bácska After his victory at Piski, Bem repelled an Austrian invasion from
Bukovina, but he lost against Puchner in the
Battle of Medgyes. However, on March 11, he defeated the Russian and Austrian troops in the
Second Battle of Nagyszeben. Hungarian forces under Colonel Hadik and later General Perczel fought on the southern front. Perczel formed the IV Corps and lifted the siege of Pétervárad. Then, as a result of the
Fourth Siege of Szenttamás, he captured the stronghold, but failed to take the
Titel Plateau. After Isaszeg, the Hungarian army moved north to relieve Komárom. On April 10, they defeated the Austrians in the
First Battle of Vác, and on April 19, routed the fresh troops coming from Austria in the
Battle of Nagysalló. Between May 16–19, Hatvani repeated his attack, but with the same results. The Romanians took revenge of these attacks, by massacring 5,000 Hungarian civilians. On 30 May, when Avram Iancu tried to attack the Hungarian forces besieging Gyulafehérvár, he was repelled. In May, Bem and Perczel expelled Serbian and Austrian troops under General Malkowski from Bánát. The V Corps laid siege to Arad and Temesvár, but lacked resources for a full assault. On 24 March, Colonel Lajos Beniczky surprised the Austrians in the
Raid on Losonc, causing a retreat and distracting Windisch-Grätz, which aided Görgei’s offensive. In April, Beniczky and Major Ármin Görgey captured towns across
Upper Hungary. In the northeast, a Hungarian victory in the
Battle of Podhering on 22 April stopped Austrian raids from
Galicia. In Southern Transdanubia, Gáspár Noszlopy led a popular uprising starting on 19 April. With growing national support, he liberated
Kaposvár by 1 May, achieved victories like the
Battle of Barcs, and expelled Austrian and Croatian troops from
Nagykanizsa. He organized new military units and produced cannons. By late May, most of the region was in Hungarian hands, except
Baranya County.
Results of the Spring Campaign By early March, Hungary controlled only eastern regions. By 14 June, nearly the entire country was liberated, except for Croatia,
Syrmia, the Central Transylvanian Mountains, and a few fortresses. The territory under Hungarian control grew from 95,000 to 250,000 km²—an impressive achievement against Europe’s second-largest empire.
Summer Campaign Situation Due to Hungary’s growing success, Austria sought help from Russia, resulting in the Treaty of Warsaw. Tsar
Nicholas I of Russia sent about 200,000 troops under Field Marshal
Ivan Paskevich to Hungary. Their goal was to quickly take Pest: Austrians advanced via Győr-Komárom, and Russians via Kassa-
Miskolc. Görgei commanded the main army with 4 corps, supported by garrisons and reserve forces in Szeged. In the
Battle of Pered (June 20–21), initial Hungarian success was reversed by disorganized coordination and Russian reinforcements. Görgei’s smaller army halted Haynau in the
Second Battle of Komárom (July 2), but Görgei was wounded and absent from the failed
Third Battle of Komárom (July 11), which aimed to open a path to southern Hungary. On June 26, Görgei proposed the concentration of troops at Komárom and defeating Haynau there before the arrival of the Russians. However, the government ordered a concentration at Szeged without informing him. Believing Görgei had disobeyed him, Kossuth dismissed him from command of the troops. Clashing with Paskevich in the
Second Battle of Vác (July 15–17), Görgei maneuvered behind Russian lines, forcing Paskevich to abandon his southern advance.
Fights in Transylvania and southern Hungary In June, Russian and Austrian forces invaded Transylvania. The Russians took Brassó and
Nagybánya, while Clam-Gallas attempted a southern link-up. Jelačić's arrival in early June led to successes like the
Battle of Káty and the burning of
Újvidék. However, his advance was halted with a defeat in the
Battle of Kishegyes (July 14), forcing a retreat. On August 3, in a surprise counterattack,
he broke the siege, inflicted heavy losses, and advanced to Győr, sparking a brief uprising in Székesfehérvár. But the victory came too late to change the war’s outcome.
Surrender In July, General Dembiński was appointed commander-in-chief in the
Tiszántúl region and united his troops with the Army of the South at Szeged to block Haynau’s crossing of the Tisza River. Subsequently, remaining Hungarian units surrendered mostly to Russian forces, and fortresses fell one by one, with Komárom holding out until early October. ==Aftermath==
