The long campaign (a.k.a. the winter campaign)
September 1443 February 1444
A) Background
By 1443 king Uladislaus managed to secure his power in most part of Hungary, although supporters of the child Ladislaus Posthumus still strongly held some territories in the kingdom. The continuous attacks of the Ottoman Empire and the earlier successes of Hunyadi showed that the Ottoman question must be solved in the military way. A successful campaign against the Ottomans could also have increased the authority and legitimacy of Vladislaus solidifing his power.
Vladislaus Jagiellon, drawing by Jan Matejko:
A campaign was also urged by Đurađ Branković, the exiled Serbian despot, who lived in Hungary since 1439 when he lost his country to the Ottomans.
After the Council of Basel-Ferrara and the controversial union with the Eastern Curch Pope Eugenius IV sent Cardinal Giuliano Cesarini as his legate to Hungary in order to organize a crusade against the Ottomans. Cardinal Cesarini successfully mediate a cease fire between Uladislaus and the party of Ladislaus Posthumus.
Pope Eugenius IV by Jean Fouquet:
In March 1443 the royal council passed an order of collecting extraordinary war tax. (1 golden forint per a serf mansion). Hungary also got financial aid from the Pope and Venice helped the crusaders with 10 thousand pounds of gunpowder. Negotiations began for sending a PapalVenetian fleet to cut Ottoman supply from Asia Minor, but this plan failed because the Pope and Venice was not able to agree about who finance the fleet.
Finally Uladislaus raised and army of 25-30 000 men. Besides the Hungarian army there were Polish troops plus Wallachian, Bosnian and Serbian (under Branković) auxiliary forces. A contingent of Crusader insurgents, armed peasants were also raised. The army had 600 Hussite warwagons with Bohemian mercenaries as crew. The warwagons were commanded by Jan Čapek a former deputy of Jan Griska. The crusader force was significant, though the king had to leave behind forces to ensure the peaceful behaviour of Ladislaus Posthumus supporters.
The aim of the of the crusade was to shake Ottoman power on the Balkans and if it is possible the capture of its capital Adrianople (modern Edirne, hung. Drinpoly). The moment was favourable. Sultan Murad II fought with the elite forces in Asia Minor against Karamania and the Balkans was defended by only the Rumelian army garrisons.
B) Events of the Campaign
Hunyadis campaigns in the Balkans:
September 1443
The campaign was launched. The Crusaders form two armies: the vanguard (12 000 men) commanded by John Hunyadi and the rest of the army led by King Uladislaus personally.
Minor Ottoman reinforcement (soldiers from some of the Anatolian sandjaks) arrives from Anatolia. The Ottoman army in the Balkans numbers cca. 20 000 men led by Khasim the beylerbey of Rumelia.
The Crusader army is numericaly superior and Ottoman forces are scattered in the Balkans. Khasim avoids open field battle and slowly retreats. He hopes that coming winter and continuous harassment will stop or at least weaken the Christians. Crusaders capture Ni without any difficulty.
November 1443
Minor Ottoman forces are harrassing the Crusader vanguard. Hunyadi defeats them one by one.
- Isa beys cavalry
- Unidentified light cavalry troops
- Turkhan beys akincis
Presumably beylerbey Khasim tried to lure the vanguard far from the main army with these minor forces. Suddenly he by-passes Hunyadi and attacks Uladislaus somewhere between Ni and Kruevac. His plan fails. Hunyadis scouts inform the voivod about the attack. Hunyadi orders forced march and manages to surprise Khasim. The beylerbey was defeated.
Murad II ends war with Karamania and hurries back to the Balkans with most of his forces, although he has to leave forces to ensure his back. He reaches Sofia. The long and fast march exhausted his forces and he does not dare to fight an open field battle. Instead of he fortify strategicaly important mountain passes.
Sultan Murad II:
The Crusaders also have difficulties. The November of 1443 was unusually cold, food supply is lessened and horseplague brokes out in the camp.
Murad II leaves Sorfia only a smaller garrison left behind. He goes to the east.
Crusaders capture Sofia.
December 1443
Trajans Gate (a mountain pass) to the south is so strongly fortified that the Crusaders chose the Zlatitsa Pass instead to reach Adrianople. But Murad have already fortified it and wait behind it with his army.
12th December 1443
The Crusaders storm the pass, but after some failed attempt Uladislaus ordered the withdrawal to Hungary.
The Crusaders are harrassed by Ottoman marauders and the Sultan orders the Garand Vizier, Khalil pasha to pursue the christians. [NOTE: Other sources mentions Khasim pasha.]
24th December 1443
Khalil pasha cathes the Crusaders up at Melstitsa. The fight remains undecided.
Hunyadi sets a trap at the Kunovitsa Pass. The army of Khalil pasha attacks the rearguard led by the despot. Branković slowly withdraw and lures the Grand Vizier in front of the full crusader army in battle order. The unexpected charge of heavy cavalry crushes the Ottoman army. Even the Ottoman camp was captured.
After this victory the Crusaders can withdraw unmolested.
13rd January 1444
The Crusader army reaches Kruevac. The despot tries to convince the king to spent the winter in Serbia, but this cant be carried out: food supply run out, many horses died by plague and the king ran out of money and unable to pay the mercenaries anymore. The army returns to Hungary
February 1444
The king triumphantly enters Buda. A great praise mass was held in the Virgin Mary Church where the coat of arms of all of those lords who took part in the crused was hung. (More precisely it is the Nagyboldogasszony Church modern Matthias Church-, but I am unable to translate it accurately.)
During the campaign the crusaders captured many important persons like the bey of Vidin, Plovdiv, Sofia, Sihabeddin former beylerbey, even the brother in law of the sultan. They also won many Ottoman banners etc.
C) Aftermath Significance
The long campaign was not a decisive one. The Crusaders reconquered no lands or castles. They did not fight with the main Ottoman army an open field battle. Though it was a significant victory. Hungary was on the defensive till the times of Sigismund. But now an army deeply penetrated Ottoman territory defeated the Turks six times and returned with the booty without any serious defeat. The expulsion of the Ottomans from Europe again seemed a possibility and Hunyadis reputation reached the skies.
Hunyadi in the Thurczy Chronicle:
Cardinal Cesarini urged a new campaign which will crush Ottoman once and for all and only after some week of rest arrangements were made for a new crusade.
But not just the Hungarians beleived that this was an important victory. Murad II realized that Hungary with its allies a dangereous threat. The Ottoman Empire cant accept a two front war with the crusaders and with Karamania. He needed time, he wanted to abdict and leave the throne to his son.
Sultan Murad II practicing archery:
The Sultan asked Branković (his father in law) to mediate a peace with Hungary. He offered to restore the Serbian State (under the despot) to pay Hungary a tribute of 100 000 gold coins and to help Hungary with an army of 30 000 men if needed. His offer was taken into consideration...
