The tale of the Three Thousand of Qohor begins four hundred or more years ago, when the Dothraki first came out of the east to sack and burn every town and city in their path. The khal who led them was named Temmo, and his khalasar numbered 50,000 at least, half of them braided warriors with bells in their hair (III: 96)
The Qohorik knew that Temmo came and strengthened their walls, doubled their guard, hired two free companies (the Bright Banners and the Second Sons), and bought 3,000 Unsullied. As the Three Thousand came to Qohor after their long march from Astapor, they saw that a battle had ended and the Dothraki had sent the sellsword companies to flight and defeated much of the Qohorik army. The horselords feasted to sack the city on the morrow, but when morning came the 3,000 Unsullied were drawn up before the gates with the Black Goat standard flying over them (III: 96, 97)
Temmo, disdaining his foes on foot, charged the Three Thousand eighteen times. The Unsullied locked their shields, lowered their spears, and stood firm against the 20,000 Dothraki screamers. Three times the khal sent his archers past, arrows raining down on the Unsullied, but they only lifted their shields. In the end only 600 Unsullied remained, but more than 12,000 Dothraki were dead upon the field, including Khal Temmo, his bloodriders, his kos, and all his sons (III: 97)
After the battle of the Three Thousand, on the fourth day as morning broke, the new khal led a procession of the survivors past the gates. One by one, each man cut off his braid and threw it down before the feet of the Three Thousand. Since then, the city guard of Qohor has been made solely of Unsullied, every one of whom carries a tall spear from which hangs a braid of human hair (III: 97)
