After halting the CCF advance, the U.N.
forces conducted a series of well executed
attacks, recevoring Seoul. Hostilities eventually ceased along on Armistice line located
near the 38th Parallel.
TIMELINE
At Inchon MacArthur conducted a masterful turning movement through the
use of a bold amphibious operation. The landings consisted of the 1st Marine
Regiment and the 7th Infantry Division from Japan, and the 5th Marine
Regiment which had been withdrawn from the Pusan Perimeter. This attack,
in combination with a breakout by the 8th army from the Pusan Perimeter,
resulted in the destruction of the NKPA as an organized fighting force.
Consequently, the Inchon invasion was follwed by the U.N. forces attacking
into North Korea where some forces advanced to the Yalu River.
