to the missionary Pian de Carpine, a part of the Alans had successfully resisted a Mongol siege on a mountain for 12 years: This twelve-year-old siege is not found in any other report, however the Russian historian A. I. Krasnov connected this battle with two Chechen folktales he recorded in 1967 that spoke of an old hunter named Idig who with his companions defended the Dakuoh mountain for 12 years against Tatar-Mongols. He also reported to have found several arrowheads and spears from the 13th century near the very mountain the battle took place at: Against the Alans and the Cumans (Kipchaks), the Mongols used divide-and-conquer tactics by first telling the Cumans to stop allying with the Alans and, after the Cumans followed their suggestion, the Mongols then attacked the Cumans after defeating the Alans. Alans were recruited into the Mongol forces with one unit called "Right Alan Guard" which was combined with "recently surrendered" soldiers, Mongols, and Chinese soldiers stationed in the area of the former Kingdom of Qocho and in Besh Balikh the Mongols established a Chinese military colony led by Chinese general Qi Kongzhi (Ch'i Kung-chih). Alan and Kipchak guards were used by Kublai Khan. In 1368 at the end of the Yuan dynasty in China Toghan Temür was accompanied by his faithful Alan guards. Mangu enlisted in his bodyguard half the troops of the Alan prince, Arslan, whose younger son Nicholas took a part in the expedition of the Mongols against Karajang (Yunnan). This Alan imperial guard was still in existence in 1272, 1286 and 1309, and it was divided into two corps with headquarters in the Ling pei province (Karakorúm). The French-Flemish monk and traveler William of Rubruck mentions Alans numerous times in the account of his 1253–1255 journey through Eurasia to the Great Khan, e.g. Alans living as Mongol subjects in Crimea, Old Astrakhan, the Khan's capital Karakorum, and also still as freemen in their Caucasian homeland ("the Alans or Aas, who are Christians and still fight the Tartars"). The reason why the earlier Persian word tersa was gradually abandoned by the Mongols in favour of the Syro-Greek word arkon, when speaking of Christians, manifestly is that no specifically Greek Church was ever heard of in China until the Russians had been conquered; besides, there were large bodies of Russian and Alan guards at Peking throughout the last half of the thirteenth and first
