...King Injo flees from Hanseong (Seoul) to Ganghwa Island in panic.

The Manchus, despite their dominance over the situation, push for peace negotiations, probably because Hong Taiji is concerned about home defenses.

Their peace offer to Korea is soon accepted, despite the opposition of some anti-Manchu statesmen who fail to appreciate the strong position of Manchus.

The following settlement is agreed upon in Ganghwa Island:

1.Korea will abandon the Ming era name Tianqi.

2.Korea will offer Yi Gak as a hostage as a substitute for a royal prince.

3. (Later) Jin and Korea will not violate each others' territory.

In the meantime, Amin in Pyongyang loots the city for days, before he is ordered by Hang Taji to sign the peace agreement, which is more favorable to the Manchus.

After the four month expedition, the Manchu army withdraws to Mukden.

The two sides conduct postwar negotiations.

The Manchus force Korea to open markets near the borders because the long conflict with Ming China has brought economic hardship to the Manchus.

Korea also returns the Warka tribe to Later Jin.

The Manchus are to exact regular tribute from Korea for the next several years.
