《史记·七十列传·匈奴列传》
匈奴又侵入渔阳，打败渔阳太守的一千多军队，把汉朝将军韩安国围困起来。这时韩安国的一千多骑兵也将要全部被歼，恰巧燕王的救兵赶到，匈奴才离去。
胡又入败渔阳太守军千馀人，围汉将军安国，安国时千馀骑亦且尽，会燕救至，匈奴乃去。
The Xiongnu also invaded Yuyang, defeating the prefect's over one thousand troops and besieging Han Anguo. At that time, Han Anguo's over one thousand cavalries were also about to be annihilated, but the reinforcements from the King of Yan arrived just in time, causing the Xiongnu to withdraw.
