巫郡 / Wu Commandery
巫郡 / Wu Commandery appears in 《资治通鉴·周纪》62丨稷儿，诓你舅舅的“腿”啊 as one of the two 楚国 regions 秦昭襄王 demands after detaining 楚怀王 in 咸阳. It is paired with 黔中 as territory Qin wants to extract from Chu by holding the Chu king.
The source stresses strategic consequence rather than geography for its own sake. If Chu yields Wu Commandery and Qianzhong, the episode says Chu’s capital region would become dangerously exposed, which helps explain why Chu Huaiwang refuses even while captive.
《资治通鉴·周纪》82丨大秦的核武器：白起来了！ later records Wu Commandery as actually captured by 白起 in 277 BCE, paired again with 黔中. The page therefore tracks a progression from Qin’s hostage-backed demand in Zhouji 62 to Qin’s later battlefield seizure and administrative consolidation in the southern campaign sequence.
