The King of Hungary, Béla IV, had summoned a council of war at Gran, a large and important settlement upriver from Buda and Pest. As Batu was advancing on Hungary from the north-east it was decided by the King to concentrate his strength at Pest and then head to the north to confront the Mongol army. When news of the Hungarian battle strategy reached the Mongol commanders they slowly withdrew, drawing their enemies on. This was classic Mongol strategy, perfected by Subutai. He prepared a battlefield and waited. It was a strong position, because woods prevented their ranks from being clearly scouted or seen, while across the river on the plain of Muhi, the Hungarian army was extremely exposed.

Subutai launched the Battle of Muhi during the night of April 10, 1241, only one day after the smaller army in Poland had won the Battle of Legnica. At Muhi, a single division crossed the river in secret to advance on the Hungarian camp from the southern flank. The main body began to cross the Sajo River by the bridge at Muhi. This was met with fierce resistance, so catapults were used to clear the opposite bank. When the crossing was completed the other contingent attacked at the same time. The result was panic, and to ensure that the Hungarians did not fight desperately to the last man the Mongols left an obvious gap in their encirclement. This, along with the feigned retreat, was one of the Mongol's most prized strategies. April 10 is the 100th day of the year in the Gregorian calendar (101st in leap years). ...

As Subutai had planned, the fleeing Hungarians poured through this apparent hole in the lines, which led to a swampy area.
