terrain, they were not accustomed to the climate or terrain of
the
south. They
were not prepared for the punishingly high temperatures of the semitropical
regions of south China. Neither were they ready for the diseases, the para-
sites,
and the mosquito-infested jungles in the south and southwest. Their
horses could not readily adjust to the heat; nor could they forage as easily in
the southern farmlands as they could in the steppe. The Mongolian troops, in
addition, needed to employ military techniques they had scarcely, if ever,
used before. To cope with the Sung navy, for example, they would be
required to construct boats, recruit sailors, and become more proficient in sea
warfare. On land, they would need to lay siege to populous, well-defended
towns and cities. In fact, the Sung had the largest population and the most
resources of any of
the
lands invaded by the Mongols. The subjugation of this
great Chinese empire would thus entail enormous expense and effort.
The Sung was, on the surface, prosperous. Such lively cities as the capital,
Hang-chou, craved and had the resources to pay for luxuries. Hang-chou had
splendid restaurants, tea houses, and theaters; "no other town had such a
concentration of wealth."

' Southern Sung prosperity derived from both
widespread domestic trade and commerce with other countries in Asia and
the Middle East. The Sung government, recognizing the potential revenues
to be garnered from trade, appointed maritime trade superintendants
(t'i-chii
shih-po sbih)
in the most important ports, employed merchants to supervise
the state monopolies and allotted them a higher status in society, and encour-
aged foreign merchants to trade with China. As the seaborne commerce
flourished, the Sung's concern for shipping and, as a result, for naval power
grew. The court developed the navy to counter piracy along the coast, and its
great ships with their rockets, flamethrowers, and fragmentation bombs
became an important branch of the Sung armed forces, posing an obstacle to
Mongolian conquest.'

Despite its commercial prosperity and its naval power, the Sung confronted
serious internal political and economic difficulties by the middle of the thir-
teenth century. Many
large
landlords had, through good management, oppres-
sion of the peasants, or favors from relatives in the bureaucracy, accumulated
vast estates and had been granted
a
tax-exempt status. As more and more land
was removed from the tax rolls, the court could not meet its fiscal obliga-
tions.
Eunuchs and relatives of the empresses played important roles in court
deliberations on policy, occasionally overruling high officials. The expendi-
