WAR AND PEACE 279
The intervention of Ming China
The Koreans, however, could not hope to expel the invaders from
their land by themselves, and it was not the various logistical and
organizational difficulties suffered by the Japanese that doomed the
first invasion to failure. Rather, its fate was sealed by an external
factor, the intervention of Korea's protector power, Ming China.
The first Chinese troops crossed the Yalu into Korea on the day
P'yongyang was occupied by the Japanese, 1592.6.15. Amounting to
no more than three thousand men, they were led into a debacle by an
overconfident commander who had them attack the far superior Japa-
nese garrison of P'yongyang
a
month later. The Chinese withdrew, but
even in defeat they inflicted a rude shock on the Japanese generals, the
more perspicacious among whom realized that it was only a matter of
time before this new enemy would reappear in strength. At the other
end of the theater of
war,
off the southeastern tip of
the
peninsula, the
Japanese naval forces were in the meantime being battered by the
Korean fleet of Yi Sun-sin and were finally ordered by Hideyoshi to
avoid engagements at sea. Hence it was clear that the initiative was
slipping from the Japanese.
Yu Song-nyong observed correctly that the Korean naval victory
spoiled the entire strategy of the invaders by "cutting off one of the
arms"
with which Japan tried to envelop Korea, isolating Konishi
Yukinaga's army at P'yongyang and securing Chinese waters from the
fear of a Japanese attack, so that "the Celestial Army could come by
land to the assistance" of Korea.

The Chinese, however, could not
commit major forces to Korea until they had dealt with a Mongol
rebellion in Ning-hsia, on the distant northwestern frontier of the
Ming Empire. They therefore initiated pourparlers with Konishi
Yukinaga, who agreed to a fifty-day truce. The Ming emissary, Shen
Wei-ching, may have intimated to Konishi that his government would

Sun-sin at Hansan Island, 1592.7.7 (7.8 in the Korean and Chinese calendar), which was
followed two days later by another off Angolp'o. See Yi Sun-sin's own report on these
