THE REIGN OF MONGKE 405
newly created realm still farther in the direction of Syria resulted, however,
in a major disaster when in September of the following year, the Egyptian
Mamluks crushed the invading armies at 'Ain Jalut and made the Mongolian
commander, Ked Bukha, their prisoner.

At the other end of Asia, the campaign against the Koreans commenced in
late 1252 under the direction of Prince Yekii (Yeh-ku), the eldest son of Jochi
Khasar, Chinggis khan's brother. Mongke's choice of commanders in this
instance was a poor one: Unreliable and insubordinate, the prince badly
mismanaged matters and so in 1253, on the khaghan's orders, was replaced
by Jalayir (Cha-la-i-erh), an officer in the imperial guard. The latter made
some progress in the next five years but was unable to overcome the Koreans'
spirited resistance, forcing Mongke to send large reinforcements to the penin-
sula in 1258. Even with fresh units in the field, it took another year of
strenuous campaigning before the Koreans reluctantly acknowledged Mongo-
lian overlordship.
On the southern Chinese front, large Mongolian forces were also in mo-
tion. In order to avoid a costly frontal assault on the Sung, which would have
required a risky forced crossing of the lower Yangtze, Mongke decided to
establish a base of operations in southwestern China, from which a flank
attack could be staged. To this end, in the late summer of 1252 he ordered
his brother Khubilai to invade and occupy the Nan-chao, or more properly
the Ta-li, kingdom ruled by the Tuan family in Yunnan, which adjoined the
Sung's more weakly defended western and southwestern frontiers.

Starting
from Shensi, the Mongolian armies reached the T'ao River, an affluent of the
upper Yellow River, in the fall. The advance force under the Chinese general
Wang Te-ch'en then penetrated the Szechwan basin, defeated the local Sung
garrisons, and established a major Mongolian base in the city of Li-chou
(later called Pao-ning). The path to the south now cleared and his lines of
communication secure, Khubilai, with the main force, advanced on the Ta-li
kingdom. In the fall of 1253, after traversing wild and mountainous terrain,
Khubilai set up headquarters on the Chin-sha River in western Yunnan.
Here he divided his troops into three columns and marched on Ta-li, the
capital of the kingdom (see Map 29).
Between December 1253 and January 1254 the kingdom was subdued,
and even though its ruler had rejected Khubilai's submission order, the
capital and its inhabitants were spared. As they had done on many other
