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which had been withdrawn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 followed by the U.N.
forces attacking into North
Korea where some forces advanced to the Yalu River.
