The second Mongol invasion of Poland was carried out by general Boroldai (Burundai) in 1259-1260. During this invasion the cities of Sandomierz, Krakow, Lublin, Zawichost, and Bytom were sacked by Mongols for the second time. In late March 1260, the Mongols left Lesser Poland, along the Carpathian foothills. The province that they had invaded was completely destroyed, with rich looty some 10,000 Poles taken with the invaders as slaves. The success of the Golden Horde was complete, as they managed to destroy an anti-Mongol alliance, and completely subjugate Kingdom of Galicia–Volhynia.
