Second_Perso-Turkic_War
The Hephthalites/Gokturk raids of 614-616, were incursions by the Hephthalites and Gokturks into the Sasanian Empire. The Sasanid army led by Smbat Bagratuni quickly defeated the Hephthalites raid who, in response, called the Gokturk Empire for assistance. The Gokturks responded with a large army that raided as far as Ray and the province of Isfahan. The raid was defeated with Smbat killing the Hephthalites leader in single combat.
