《资治通鉴·唐纪·唐纪三十二》
不久，哥舒翰又派人于赤岭西部开垦屯田，并派遣了二千犯罪充军的士卒去守卫龙驹岛。冬天结冰封冻以后，吐蕃大军来攻，将守卫的士卒全部消灭。
顷之，翰又遣兵于赤岭西开屯田，以谪卒二千戍龙驹岛；冬冰合，吐蕃大集，戍者尽没。
Soon after, Geshu Han ordered his men to open up fields for farming east of Chilong and dispatched 2,000 exiled convicts to garrison Longju Island. After the winter froze the rivers, the Tubo army invaded, annihilating all of the garrison.
