The descriptions of Indian treatises on strategy raise many questions that Roy does not answer. For example, Indian monarchs seemed to always lack cavalry of sufficient quality and quantity. Yet no king ever tried to address this shortcoming by importing and breeding horses in India. Kalhana, the author of Rajatarangini, mentions that the Palas and Senas of Bengal attempted to import cavalry from Afghanistan and South China, and the Hoysalas tried to crossbreed Arab mares with local breeds to no avail. When the Romans, Greeks, Persians, and Carthaginians could take elephants from India, why could Indian traders not acquire war horses? Although the problem of a weak cavalry was temporarily solved under some kings such as Vikramaditya of the Gupta dynasty or Harshavardhana of Thaneshwar and Kanauj, it remained an issue until the very end. In relation to the equine lacuna, India did not develop metal stirrups or horseshoes until much later either and this gave the Hunnic mounted archers a tremendous advantage in battle; the invaders’ composite bows also gave them greater range than their Indian opponents. Why did Indian rulers fail so spectacularly in developing or acquiring military technology despite their use of spies or their fame in trade? This would have been an important question in a military history of South Asia.
