In 1272, the great khan sent an army of 12,000 veteran troops, under the command of aft experienced officer, named Nestardin, to reduce the kingdom of Vociam and Guarazan[8]. As soon as the kings of Mien[9] and Bengala heard of this invasion, they assembled an army of 60,000 horse and foot, besides a thousand elephants, carrying castles, in each of which there were from twelve to sixteen armed men. With this army, the king of Mien marched towards the city of Vociam, where the Tartar army was encamped. Nestardin, regardless of the great disparity of numbers, marched with invincible courage to fight the enemy; but when he drew near, he encamped under cover of a great wood, knowing that the elephants could not penetrate into the wood with the towers on their backs. The king of Mien drew near to fight the Tartars; but the Tartarian horses were so terrified with the sight of the elephants, who were arranged along the front of the battle, that it was impossible to bring them up to the charge. The Tartars, therefore, were compelled to alight from their horses, which they fastened to the trees, and came boldly forewards on foot against the elephants, among whom they discharged immense quantities of arrows; so that the elephants, unable to endure the smart of their wounds, became unmanageable, and fled to the nearest wood, where they broke their castles, and overturned the armed men, with which they were filled. On this, the Tartars remounted their horses, and made a furious attack on the enemy. The battle continued for some time undecided, and many men were slain on both sides. At length the army of the king of Mien was defeated and put to flight, leaving the victory to the Tartars; who now hastened into the wood, and made many prisoners, by whose assistance they seized two hundred of the elephants, which were sent to the great khan. Before this time, the Tartars were unaccustomed to the use of elephants in war; but the great khan has ever since had elephants in his army. After this victory, the great khan subjected the kingdoms of Mien and Bengala to his empire.
