After this other great battles were fought between the two armies. At one of them, a great trumpet fifteen feet long is mentioned among the other martial instruments that were used to excite the men to ardor in making the charge.
The Monguls victorious.
The sultan's plans.
In these battles the Monguls were victorious. The sultan, however, still continued to make head as well as he could against the invaders, until at length he found that he had lost one hundred and sixty thousand of his men. This was almost half of his army, and the loss enfeebled him so much that he was convinced that it was useless for him any longer to resist the Monguls in the open field; so he sent off his army in detachments to the different towns and fortresses of his kingdom, ordering the several divisions to shut themselves up and defend themselves as well as they could, in the places assigned to them, until better times should return.
Flying squadron.
The sultan, however, did not seek shelter in this way for himself. He selected from his troops a certain portion of those who were most active and alert and were best mounted, and formed of them a sort of flying squadron with which he could move rapidly from place to place through the country, wherever his aid might be most required.
Genghis Khan.
Genghis Khan, of course, now prepared to attack the cities where the several divisions of the sultan's army had intrenched themselves. He wished first to get possession of Otrar, which was the place where the embassadors and the merchants had been massacred. But the city was not very large, and so, instead of marching toward it himself, he gave the charge of capturing it to two of his younger sons, whom he sent off for the purpose at the head of a suitable detachment.
He himself, with the main body, set off upon a march toward the cities of Samarcand and Bokhara, which were the great central cities of the sultan's dominions.
