A single Tatar would enter a village with crowds of people and start killing them one by one, and none of the Muslims would dare to raise his hand towards him to attack him or even defend himself.
A Tatar happened to catch hold of a Muslim, and he had no sword, thereupon he told the Muslim to stay with his head on the ground until he came back to him. The Muslim did so accordingly and the Tatar went, fetched a sword and came back and killed him.

Another Muslim said to Ibn Al-Atheer, May Allaah have mercy upon him, “I was walking along with seventeen persons, when a Tatar appeared and ordered us to tie each other up. My companions started to implement his orders. I said to them: he is only one person; why should we not kill him and flee? They expressed their fear. I said to them: He intends to kill you. Let us kill him, perchance Allaah the Almighty would save us. By Allaah, nobody dared to do so until I took a knife and killed him and we all fled.”
There are many like those scenes!

The Tatars entered a small town called Bitlis, now south of Turkey. Because it only had a narrow path between the mountains, it was strongly impregnable. So one of its residents used to say that if they had 500 horsemen, no Tatar would have survived, for in this path, few would be able to defeat many. But even, exalted be Allaah! Its inhabitants took shelter in the mountains and left their city exposed to the Tatars, who came and burnt it down.

Every Muslim before being killed by a Tatar, used to beseech him by Allaah not to kill him, saying: “No, by Allaah, don’t kill me.” That expression was heard so much by the Tatars that they used to sing it repeatedly. A Muslim hid himself from the Tatars in an abandoned house, said: "I saw the Tatars from the window of the house; after having killed the men and captured the women, they rode their horses and said while laughing and dancing: No by Allaah, no by Allaah."
That is, as put by Ibn Katheer, May Allaah have mercy upon him, "the greatest overwhelming calamity and the most severe disaster; and we all belong to Allaah, and to Him we shall return. That was the state of the Muslims at that time; a bitter psychological defeat and a horrible Tatar invasion.
