For its involvement, the X Corps received the Philippine Presidential Unit Citation with a streamer embroidered 17 October 1944 – 4 July 1945.

The US Army's 7th Infantry Division, which had landed later at Inchon, engaged the enemy on the outskirts of Seoul, destroying an armored regiment.

This action proved to be a mistake as Republic of Korea Army (ROK) forces moving by land captured Wonsan on 11 October before the X Corps assault went in.

The Chinese People's Volunteer Army (PVA) entered the war on the side of North Korea, making their first attacks in late October.

X Corps was strung out along many miles in sub-freezing temperatures with the ROK troops and the 7th Infantry Division to the north in contact with PVA forces.

The Marines managed to reach the safety of Hungnam first, where the 3rd and 7th Infantry Divisions and I ROK Corps provided perimeter defense.

However, after it entered the main line, conventional military doctrine indicated that it should have been placed immediately under the command of Eighth Army.

After the withdrawal from the northeast coast, and once its units had been reconstituted, X Corps went into the line in eastern Korea, and remained there for the rest of the war.

The fourteen area corps were inactivated; in their place, eighteen army reserve commands ("ARCOMs") were established.
