Khostovrul (Russian: Хостоврул; died January 1238) was a Golden Horde valiant warrior, according to The Tale of the Destruction of Ryazan,[1] who died in a single combat with the Russian military commander Evpaty Kolovrat.
Evpaty Kolovrat was visiting Chernigov at the time of the Siege of Ryazan, which occurred between 16 and 21 December 1237.
Learning about the tragedy, he rushed back home, only to find the city destroyed and most its inhabitants killed.
Kolovrat's forces suddenly attacked the rear-guard of Batu Khan's army and annihilated it in a fierce battle.
Khostovrul promised Batu Khan to capture Evpaty Kolovrat alive and led the squad.
