For two days’ walk a trail of corpses lead from the bridge over the Sajo River. Arrows protruding from fallen Hungarians, limbs bent at unnatural angles, leading to a dense marsh where armoured bodies lay sunk in the bloodied water. Riders picked over the bodies, collecting unbroken arrows, still usable weapons and armours while finishing off survivors. Great piles of loot were made, to be divided among the troops, and Batu Khan, grandson of Chinggis, took the royal tents of the Hungarian King, Bela IV, for himself. Bela had escaped, but the Mongol riders would pursue. In the aftermath of the carnage at the battlefield at Mohi, the rest of the Hungarian Kingdom and Europe itself seemed open to Mongol horsemen. Batu and Subutai may have envisioned leading their men into the cities of Italy, Germany and France, but within  a year they pulled their forces back from Europe. I’m your host David, and this is Kings and Generals: Ages of Conquest.   The Mongols considered the battle of Mohi, over the 10th and 11th of April, 1241, among their greatest victories, a hard fought battle over a determined enemy. Though the battle over the bridge was close, Mongol losses running high and certain princes wishing to retreat, in the end Batu and Subutai outplayed the Hungarians and destroyed the royal army. Yet King Bela IV had escaped, as had his brother Prince Coloman, and a number of Hungarian nobles had not been present, never providing their troops to Bela in the first place. Nonetheless, the battle’s outcome was a massive disaster for the Hungarians. Alongside the sheer volume in manpower lost, many of the Kingdom’s highest ranking figures had been killed. From top bishops, archbishops, the Knights Templar within the Kingdom, to Bela’s chancellor, were among the fallen. In one stroke, the head of the Hungarian administrative apparatus was nearly severed. Though Bela and his brother Coloman survived, they were on the run, desperate to get as far from the Mongols as possible. In the even terrain of the Great Hungarian Plain east of the Danube River, it was hard to get far enough.    Prince Coloman reached Pest, where the Hungarian army had rode from so confidently a week prior. He urged the inhabitants to flee, but was rebuffed, the wall-less town choosing then to begin building ditches and defences. Coloman rode on to Zagreb in Croatia where he succumbed to his injuries in May. Bela rode to his territories west of the Danube River, near the Austrian border where his wife and young children were. There they were invited to seek refuge in Austria by its Duke, Frederick. Bela headed to the Austrian fortress of Hainburg, where he was promptly imprisoned, the Austrian Duke demanding an exorbitant ransom from the Hungarian King: at least 1,000 marks in coin, another 1,000 in gold, silver vessels, jewels, and five western counties of Hungary to be ceded to Frederick. Bela reluctantly paid, then rejoined his family in Hungary before fleeing south to Croatia. Duke Frederick sought to take these territories by force, but due to local resistance, was only able to hold three. Angered, he began extorting money from refugees seeking shelter in Austria! Bela reached Zagreb around May 18th, in time to bury his dear brother Coloman, in some accounts forced to give him an unmarked grave to avoid it being descretated by the Mongols. In his absence, Hungary was left to the Mongols. In the Hungarian Plain where fortifications sat on level ground and consisted of wood or earthworks, the Mongols were unstoppable. Historical sources and archaeology show horrific destruction, depopulation and indiscriminate slaughter. In some regions of the plain population loss reached as high as 70% , many villages permanently abandoned. Remains of people trapped within burning buildings abound. The few locations built in difficult to access sites, such as mountaintops or thick marshand protected with stone, fared better, but these were rare and of little consolation to the majo
