In 512 BC, Wu launched a large expedition against the large state of Chu, based in the Middle Yangtze River. A similar campaign in 506 succeeded in sacking the Chu capital Ying. Also in that year, war broke out between Wu and Yue and continued with breaks for the next three decades. Wu campaigns against other states such as Jin and Qi are also mentioned. In 473 BC, King Goujian of Yue finally conquered Wu and was acknowledged by the northern states of Qi and Jin. In 333 BC, Yue was in turn conquered by Chu.
