Battle of Mór The Battle of Mór was a battle in the Hungarian Revolution of 1848 , fought on 30 December 1848 between Austria and Hungarian insurgents . The Austrians were led by Croatian Ban Josip Jelačić , while the Hungarians were led by Mór Perczel . The Austrians were victorious and Buda lost it is independence . Pretext . In the summer of 1848 two separated armies were defending the Western Hungarian borders . Major General Artúr Görgey with his army between Channel Nádas and Lake Fertő was against Alfred I , Prince of Windisch - Grätz . Major General Mór Perczel led approximately 10 , 000 soldiers and tried to defend Međimurje against Laval Nugent who was stationed at Styria . Hoping the Austrians would not attack , the Hungarian military leadership started to establish new troops and organise their forces . But , on 14 December , Windisch - Grätz started his attack and this meant a new period of the Revolution . This is called the " Winter Campaign " . The larger Austrian army managed to break through the Hungarian defence . The Hungarian army started to retreat towards Győr and Buda . Lajos Kossuth tried to convince Görgey to continue the fight , and he sent more legions from other theatres of battle to help . On 16 December Perczel received an order that he was to make contact with Görgey . This meant that the Hungarian troops gave up South Transdanubia without a fight . In his dispatches Kossuth commanded Görgey and Perczel to engage the Austrians . Kossuth made a mistake , as he knew that Perczel needed little encouragement to start a fight . On 30 December Perczel was in Mór when he received Kossuth ' s letter and , even though his more - educated officers advised him not to fight , he undertook the battle . Before the battle Perczel forgot to inform Görgey of his decision even though he was close by . Battle . Perczel ’ s legion contained approximately 6 , 500 soldiers and 24 cannon . The northern area near Mór was disadvantageous , because it was surrounded by a forest which the Austrians could easily break through . Perczel had determination , and the fact that the Austrians had a smaller army there made him more confident . But he did not reconnoitre the Austrians , so he did not realise how powerful they were . The Hungarian artillery stopped Jelačić ’ s front line and they were advancing when Ferenc Ottinger ' s front line arrived . The balance of forces significantly changed . Jelačić ’ s legion had fewer soldiers than Perczel ’ s , but Jelačić and his legion were more powerful . The weak and barely fighting Hungarian soldiers escaped to the forest . They managed to save almost all of the artillery but Perczel could only reorganize his legion in Székesfehérvár . The loss to Hungary was about 2 , 500 men , most of them were taken prisoner . They also lost at least 5 cannon . Aftermath . Hearing the news that Perczel lost the battle , Görgey withdrew again in fear that Jelačić would surround the Hungarian army from the south . The legion on the Upper Danube had to protect almost every road to Buda . Because of this they moved closer to Buda , the capital city , as it was in danger from the Austrians . On 31 December the Government decided to decamp to Debrecen . On 2 January 1849 the Council of War decided not to fight for the empty Buda and Pest . Three weeks after the start of the Winter Campaign Windisch - Grätz marched on Buda .
