臧覇
Later, during the Battle of Ruxu in 213, Zhang Liao and Zang Ba both led the vanguard. However, Sun Quan's generals laid a solid defence line despite their inferiority in numbers; when Cao Cao's forces tried to break that line with a charge, Sun Guan went to the foremost of the vanguard and was fatally injured (albeit being saved by Zang Ba on the field, Sun Guan died in camp). The progress was worse than expected, especially when continuous rainfall had raised the water level, the huge army under Zhang Liao and Zang Ba felt uneasy when enemy warships moved forward. When Zhang Liao wanted to retreat without permission, Zang Ba told him, "Cao Cao is wise, and (he) will not simply abandon us." The next day, an official order to retreat indeed arrived, and both generals safely returned to their territory. Zhang Liao told Cao Cao of what happened, and Cao Cao was greatly impressed. Thereafter, Zang Ba moved to Juchao with Xiahou Dun to resist potential invasions from Sun Quan, and was supposed to have taken part in Battle of Xiaoyao Ford, albeit playing a minor role in the campaign.
