Huo Jun was from Zhijiang County (),
Nan Commandery (),
Jing Province, which is in present-day
Zhijiang, Hubei. His elder brother, Huo Du (), rallied a few hundred men from their hometown to form a militia. After Huo Du's death,
Liu Biao, the Governor () of Jing Province, put Huo Jun in command of the militia. When Liu Biao died in late 208, Huo Jun led his followers to join the warlord
Liu Bei, who previously took shelter under Liu Biao. Liu Bei appointed Huo Jun as a General of the Household (). Around 211, Liu Bei led an army from Jing Province to
Yi Province (covering present-day
Sichuan and
Chongqing) to assist the provincial governor
Liu Zhang in countering a rival warlord,
Zhang Lu, in
Hanzhong Commandery. In 212, when
conflict broke out between Liu Bei and Liu Zhang, the former led his forces from Jiameng () to attack the latter, leaving behind Huo Jun to defend Jiameng. At the same time, Zhang Lu sent his general Yang Bo () to entice Huo Jun to defect to Zhang Lu, by offering to defend Jiameng together with him. Huo Jun replied to Yang Bo, "You can take a
xiaoren's head but not a fortress." Yang Bo therefore retreated. Later, Liu Zhang sent his officers Fu Jin (), Xiang Cun () and others to lead an army of ten thousand soldiers to attack Jiameng. Huo Jun had only a few hundred troops with him but he managed to hold his position for a year. When he saw that the enemy was weak and negligent, he selected elite soldiers from among his men and launched a counterattack on Liu Zhang's forces, greatly defeated them and beheading Xiang Cun in battle. In July 214, Liu Zhang surrendered to Liu Bei, after which Yi Province came under the latter's control. In recognition of Huo Jun's contributions during the campaign, Liu Bei partitioned a new commandery, Zitong (), from the original Guanghan Commandery (), and appointed Huo Jun as the Administrator () of Zitong. Huo Jun was also promoted to the rank of a Major-General (). He held office for three years before dying at the age of 40 (by
East Asian age reckoning). His body was transported to
Chengdu (the capital of Yi Province) for burial. Liu Bei deeply lamented Huo Jun's death and personally led his subjects to offer sacrifices and attend Huo's funeral. ==Family==
