Battle of Sajó River
The Battle of Sajó River, which took place on the night of April 11, 1241, was a significant conflict during the Mongol invasions of Europe. King Béla IV of Hungary led his army to confront the advancing Mongol forces, initially believing they had achieved victory after repelling a small Mongol unit at a nearby bridge. However, the Mongols, under Batu Khan, launched a coordinated two-pronged attack that ultimately outmaneuvered and encircled the Hungarian forces. Despite a valiant defense of the bridge, the Hungarians faced overwhelming odds due to the Mongols' superior numbers and tactics, leading to devastating losses. The battle concluded with the near-total destruction of the Hungarian army, resulting in significant casualties among the kingdom's leadership. Following this defeat, Hungary's defenses crumbled, allowing Mongol forces to occupy eastern Hungary and continue their advance across the Danube in the subsequent winter. The Battle of Sajó River thus marked a turning point in the Mongol incursions into Europe, significantly altering the political and military landscape of the region.

Battle of Sajó River
Type of action: Land battle of the third Mongol invasion of Eastern Europe
Date: April 11, 1241
Location: On the margins of the river Sajó, near the village of Mohi, Hungary, county of Borsod-Abaúj-Zemplém.
Combatants: Hungarians vs. Mongols
Principal commanders:Hungarian, King Béla IV; Mongol, Batu Khan
Result: Overwhelming Mongol victory
On the night of April 11, 1241, the armies of King Béla IV of Hungary camped on the margins of the Sajó River, not far from a bridge, on their march east to face the invading Mongol armies. After repelling a Mongol unit at the bridge, the Hungarians returned to the camp, thinking that they had won the day. The Mongols, however, followed up with a two-pronged attack, with Batu Khan’s forces attacking the bridge and Subatai’s fording the river at an undetermined location, thereby encircling the Hungarians. Though the bridge was fiercely defended, the Hungarians were overwhelmed by the Mongols’ numerical superiority and tactics.
Crowded in the camp, the Hungarians suffered huge losses to the Mongol archers. King Béla IV succeeded in escaping northward, traveling toward Pozsony (Bratislava). Although the Mongols suffered considerable losses, the Hungarian army was utterly destroyed. A substantial part of the kingdom’s leadership was killed. After Mohi, Hungary’s defenses collapsed, and, in that year, only the Danube served as a barrier to the Mongol advance.
Significance
The defeat at the Sajó River crushed the ability of the Hungarian leadership to mount a concerted defense against the Mongol forces. The armies of Batu Khan occupied eastern Hungary in 1241 and crossed the Danube in the winter of 1242.
