This Chapter from The Art of War detail a dialogue between King Wu and Jiang Taigong concerning the strategic use of cavalry. Jiang Taigong outlines ten situations where cavalry are advantageous and nine where they are disadvantageous. The ten advantages emphasize exploiting enemy weaknesses and vulnerabilities, while the nine disadvantages highlight terrain-based pitfalls and tactical errors. The discussion focuses on the importance of battlefield awareness, exploiting terrain, and understanding the limitations of cavalry. King Wu ultimately acknowledges the strategic wisdom imparted by Jiang Taigong's analysis.
