930年代末Khazar baliqchi Pesakh击败了Rus。 根据一位940年代Khazarian犹太人写的匿名信，罗斯王子奥列格（Oleg）一夜占领了卡扎尔控制的城市Tmutorokan。 著名的Khazar baliqchi（州长）Pesakh知道了奥列格的行径，并征服了属于拜占庭人的克里米亚几个城市，并且还废除了许多罗斯。 奥列格（Oleg）被击败，被迫向总督佩萨克（Pesakh）投降。 这是Khazar对Rus的重大胜利。
原文：late 930s Khazar baliqchi Pesakh defeated the Rus. According to an anonymous letter written by a Khazarian Jew in the 940s, the Rus prince Oleg captured the Khazar-held city Tmutorokan one night. Pesakh, a prominent Khazar baliqchi (governor), learned of Oleg’s actions and conquered several Crimean cities belonging to the Byzantines and also did away with many Rus. Oleg was badly defeated, and was forced to surrender to Governor-General Pesakh. This was a major Khazar victory over the Rus.
