The Battle of Keresztes (also known as the Battle of Mezőkeresztes) (Turkish: Haçova Muharebesi) took place on 24–26 October 1596. It was fought between a combined Habsburg-Transylvanian force and the Ottoman Empire near the village of Mezőkeresztes (Turkish: Haçova) in modern-day northern Hungary. The Ottomans routed the Habsburg-led army but due to their own losses were unable to exploit their victory.
On 23 June 1596, the Ottoman army marched from Constantinopole. Commanded by Sultan Mehmed III, the army marched through Edirne, Filibe (now known as Plovdiv), Sofia, and Niš to arrive at Belgrade on 9 August. On 20 August, the army crossed the River Sava by bridge and entered the Austrian territory of Siren. A war council was called at Slankamen Castle, and it was decided that they would begin a siege on the Hungarian fort of Eger (Erlau). The fort controlled the communication routes between Habsburg Austria and Transylvania, all of whom were in revolt against Ottoman suzerainty.
However, news soon arrived that the Austrians had besieged and succeeded in taking over the Castle of Hatvan and had brutally killed all the Ottomans housed there, including the women and children. The Ottoman army started a siege of the fort of Eger on 21 September 1596, and by 12 October the castle had capitulated. As retaliation for the Hatvan castle massacre, the defenders of the castle were all executed.
Not long after, Ottoman command received the report that a mixed army of Austrians and Transylvanians were advancing towards the Ottoman expeditionary force. A war council in the castle of Hatvan was conducted under Grand Vizier Damat Ibrahim Pasha. It was decided that the Ottoman army should march out of Erlau castle so as to meet the Austrians at a suitable battle terrain. The Sultan thought that the Ottoman army should disengage and return to Constantinople; it was with great difficulty that he was persuaded to engage the enemy forces.[6] [7] The Christian army had 10,000 Austrians, 4,000 Germans, 3,000 reiters, 13,000 Hungarian light cavalry and 10,000 Transylvanians, and additional troops from fifteen other European countries for a total of 55,000 men.
The Ottoman army marched through several passageways of marshy terrain and reached Haçova (Turkish meaning: Plain of the Cross), exhausted after a long siege and a hard, long march. The two armies faced each other on the plains of Haçova (Hungarian: Mezőkeresztes). The Austrian-Transylvanian army, under the joint command of Archduke Maximillian III of Austria and Prince Sigismund Bathory of Transylvania, was in position in fortified trenches. When the Ottoman army attacked the Austrian trenches, the Battle of Haçova commenced and continued for two days, from 25 to 26 October 1596. Early firearms (cannons, muskets) were used extensively in the battle. The Austrians, being entrenched around the old ruined church, succeeded in driving back the Ottoman assaults with a barrage of fire from muskets and 100 cannon.
By the second day of battle the Ottoman army appeared to have been defeated. According to the 17th Century Ottoman historian İbrahim Peçevi:
Commander Sultan Mehmed III wanted to flee from the battlefield. However, first he asked for the opinion of his tutor, the high cleric Hoca Sadeddin Efendi, who told the Sultan that he should continue the battle till the end. Heeding this advice, Sultan Mehmed III ordered that the battle should continue.
On the second day of the battle, the fighting intensified. Troops from the Austrian army had reached the Sultan's tent, which was surrounded by the viziers and the teachers at the Palace Pages School for protection. While some troops were trying to enter the Sultan's tent, the other Austrian army's soldiers disengaged, in search of booty and plunder instead of continuing the engagement. The Ottoman horse groomers, cooks, tent makers, and camel minders retaliated against the plunderers with whatever arms they could find, including cooks' spoons, blocks of wood, hammers for tent making, adzes, and axes for cutting wood. The Austrians were surprised and retreated in confusion. The cries of "the Christian enemy is fleeing" were heard by the Ottoman troops still fighting what seemed like a losing battle on the frontline. The boost of morale allowed them to recover the battle. With a major action from the Ottoman artillery cannons, the Ottoman forces started another attack on the Austrians across the front and the remaining Ottoman cavalry outflanked the Austrian-Transylvanian army, routing them.[8]
Soon after victory, Mehmed III appointed Cigalazade Yusuf Sinan Pasha as the new Grand Vizier. He sent an imperial victory proclamation to Constantinople giving the news of the conquering of Eger (Erlau) Castle and the victory at the Battle of Haçova (Keresztes). This reached Constantinople in October and there were public celebrations and public meetings organized in the city. During these celebrations, four galleys full of state-procured sugar from Egypt arrived at the Golden Horn, which added "sweetness" to the news of a military victory. Mehmed III was awarded the epithet of 'Conqueror of Egri'.
The Sultan's army marched for a month, returning to Constantinople victorious. Mehmed III returned to Constantinople in November to a triumphal reception. His victory at Keresztes had turned him into a hero. The imperial Ottoman army returned to Constantinople victorious and were greeted happily by the residents of Constantinople. With the army in place, a great victory procession and many accompanying spectacles were carried out. The poets of Constantinople wrote special works about the victory. In the streets and markets of the city, town-criers were sent to announce that the streets of the city would be decorated to celebrate the great victory. Mehmed III wanted to celebrate this victory with great splendour. The warehouses and stores were all decorated with 'valuable cloths'. This display of colour all across the city is described in a poem by the poet [Kemal]:
The Christians lost 23,000, while the Ottomans suffered 20,000–30,000 casualties.[9] [10] [11] [12]
