and of course the 13 chapters must have been written earlier still. But at that time, and for several years after, down to the capture of Ying in 506, 楚 Ch‘u, and not Yüeh, was the great hereditary enemy of Wu. The two states, Ch‘u and Wu, had been constantly at war for over half a century, whereas the ﬁrst war between Wu and Yüeh was waged only in 510, and even then was no more than a short interlude sandwiched in the midst of the ﬁerce struggle with Ch‘u. Now Ch‘u is not mentioned in the 13 chapters at all. The natural inference is that they were written at a time when Yüeh had become the prime antagonist of Wu, that is, after Ch‘u had suffered the great humiliation of 506. At this point, a table of dates may be found useful.
Accession of Ho Lu.
Ho Lu attacks Ch‘u, but is dissuaded from entering 郢 Ying, the capital. Shih Chi mentions Sun Wu as general.
Another attack on Ch‘u.
Wu makes a successful attack on Yüeh. This is the ﬁrst war between the two states.
Ch‘u invades Wu, but is signally defeated at 豫章 Yü-chang.
Ho Lu attacks Ch‘u with the aid of T‘ang and Ts‘ai. Decisive battle of 柏舉 Po-chü, and capture of Ying. Last mention of Sun Wu in Shih Chi.
Yüeh makes a raid on Wu in the absence of its army. Wu is beaten by Ch‘in and evacuates Ying.
Ho Lu sends 夫差 Fu Ch‘ai to attack Ch‘u.
勾踐 Kou Chien becomes King of Yüeh.
Wu attacks Yüeh, but is defeated by Kou Chien at 檇李 Tsui-li. Ho Lu is killed.
- When Wu first appears in the Ch‘un Ch‘iu in 584, it is already at variance with its powerful neighbour. The Ch‘un Ch‘iu first mentions Yüeh in 537, the Tso Chuan in 601.
- This is explicitly stated in the Tso Chuan, 昭公 XXXII, 2: 夏吳伐越始用師於越也.
