The Oldest Military Treatise in the World
"The Art of War is a Chinese military treatise written during the 6th century BC by Sun Tzu. Composed of 13 chapters, each of which is devoted to one aspect of warfare, it has long been praised as the definitive work on military strategies and tactics of its time.
The Art of War is one of the oldest and most famous studies of strategy and has had a huge influence on Eastern military planning , business tactics, and beyond. First translated into a European language in 1782 by French Jesuit Jean Joseph Marie Amiot, it had been credited with influencing Napoleon, the German General Staff, and even the planning of Operation Desert Storm. Leaders as diverse as Mao Zedong, Vo Nguyen Giap, and General Douglas MacArthur have claimed to have drawn inspiration from the work.
The Art of War has also been applied, with much success, to business and managerial strategies."

If I recall correctly the version on these pages originally came from Project Gutenberg (http://www.gutenberg.org). It was translated from the Chinese by Lionel Giles in 1910. I've done things like remove the commentary, check and localise the spelling ... colour is colour not color etc. I'm trying to track a down another version from somewhere to blend the two of them, creating a version that takes the different interpretations and adds my thoughts to it a bit more.
