Vikram and the Vampire by Richard F. Burton

In the venerable city of Bardwan, O warrior king! (quoth the Vampire) during the reign of the mighty Rupsen, nourished one Rajeshwar, a Rajput warrior of distinguished fame. By his valour and conduct he had risen from the lowest ranks of the army to command it as its captain. And arrived at that dignity, he did not put a stop to all improvements, like other chiefs, who rejoice to rest and return thanks. On the contrary, he became such a reformer that, to some extent, he remodelled the art of war.

Instead of attending to rules and regulations, drawn up in their studies by pandits and Brahmans, he consulted chiefly his own experience and judgment. He threw aside the systematic plans of campaigns laid down in the Shastras or books of the ancients, and he acted upon the spur of the moment. He displayed a skill in the choice of ground, in the use of light troops, and in securing his own supplies whilst he cut off those of the enemy, which Kartikaya himself, God of War, might have envied. Finding that the bows of his troops were clumsy and slow to use, he had them all changed before compelled so to do by defeat; he also gave his attention to the sword handles, which cramped the men's grasp, but which having been used for eighteen hundred years, were considered perfect weapons. And having organised a special corps of warriors using fire arrows, he soon brought it to such perfection that, by using it against the elephants of his enemies, he gained many a campaign.
