Sun Tzu have been available to Sun Wu. Additionally, there are no records of professional generals during the Spring and Autumn period; these are only extant from the Warring States period, so there is doubt as to Sun Tzu's rank and generalship. This caused much confusion as to when "The Art of War" was actually written. The first traditional view is that it was written in 512 BC by the historical Sun Wu, active in the last years of the Spring and Autumn period (c. 722–481 BC). A second view, held by scholars such as Samuel Griffith, places "The Art of War"
Sun Tzu most of the notable figures from the Spring and Autumn period. The name "Sun Wu" () does not appear in any text prior to the "Shiji", and may have been a made-up descriptive cognomen meaning "the fugitive warrior": the surname "Sun" can be glossed as the related term "fugitive" ("xùn" ), while "Wu" is the ancient Chinese virtue of "martial, valiant" ("wǔ" ), which corresponds to Sun Tzu's role as the hero's "doppelgänger" in the story of Wu Zixu. The only historical battle attributed to Sun Tzu, the Battle of Boju, has no record of him fighting in that battle.
