《梁书·列传·卷十》
不久，建安戍被北魏军队围困，又任命夏侯详为建安戍主。带边城、新蔡二郡太守，并都督光城、阳和汝阴三郡的兵力前去救援夏侯详率领救兵到达建安后，北魏祇好退兵在这之前，北魏军队在淮河上游设置荆亭戍，常常出来侵犯边境劫掠财物。
顷之、建安戍为魏所围，仍以详为建安戍主，带边城、新蔡二郡太守，并督光城、弋阳、汝阴三郡众赴之。详至建安，魏军引退。
Soon, the Jian'an Garrison was besieged by the Northern Wei army, and Xiahou Xiang was appointed the commander of Jian'an Garrison again. He brought the prefects of Biancheng and Xincai counties and supervised the troops of Guangcheng, Yanghe, and Ruyin counties to rescue the garrison. After Xiahou Xiang led his troops to Jian'an, the Northern Wei troops had to retreat. Before this, the Northern Wei army had set up a garrison at Jingting on the upper reaches of the Huai River, and often invaded the border to loot property.
