Han Zhao
After Emperor Min assumed the throne in 313, Sima Bao, whose troops were still sizable, was given the title of right prime minister (右丞相), but while he took occasional campaigns to relieve Emperor Min's government, then at Chang'an, from pressures being applied by Han Zhao forces, he took no actual actions to put Emperor Min under his protection. Indeed, in 316, when his generals briefly defeated Han Zhao forces seeking to siege Chang'an, they stopped short of reaching Chang'an, which was then captured by Han Zhao forces, causing Emperor Min to be captured.
