Despite these preparations for trouble on the left flank, the KMCs on the right and the 5th Marines in the center were first in the Division to come under attack. During the last minutes of 22 April the 2d KMC Battalion had it hot and heavy on Hill 509. To the left the 1st KMC Battalion, partially encircled, notified the 5th Marines of a penetration.

The effects were felt immediately by 1/5, with its CP in Hwachon. Hill 313 was the key to the town, being located at the Hwachon end of a long ridge forming a natural avenue of approach from the northeast. Captain James T. Cronin’s Baker Company of 1/5 had the responsibility for protecting the CP and shifting troops to the right flank if necessary. He sent Second Lieutenant Harvey W. Nolan’s platoon to run a race with the enemy for the occupation of Hill 313. Attached in excess of T/O for familiarization was Second Lieutenant Patrick T. McGahn.[164]

About 220 yards from the summit the slope was so steep that the Marines clawed their way upward on hands and knees. The company commander posted the attached light machine gun section while Nolan, McGahn, and Sergeant William Piner organized the assault. The three squads of riflemen advanced a few yards, only to be pinned down by well directed CCF machine gun fire. Another rush brought the Marines closer to the enemy but a stalemate ensued in the darkness. Seven of the platoon were killed and 17 wounded.

The situation in the 1/5 area was so serious that Fox Company of 2/5 (Lieutenant Colonel Glen E. Martin) sent reinforcements. At dawn, however, Hill 313 proved to be abandoned by the enemy. A vigorous KMC counterstroke had swept the Communists from Hill 509, so that the front was relatively quiet in this area. The courage and determination of the KMC Regiment were praised by General Smith, who sent this message on the morning of the 23d to Colonel Kim, the commanding officer:

Congratulate you and your fine officers and men on dash and spirit in maintaining your positions against strong enemy attacks. We are proud of the Korean Marines.[165]

It is taking no credit away from the KMCs and 5th Marines to point out that they appear to have been hit by enemy holding attacks. The main CCF effort was directed at the left of the Division line, held by the 7th Marines.

The heaviest fighting took place in the sector of 1/7 on the extreme left, commanded by Major Webb D. Sawyer. It was obvious that the enemy planned to widen the penetration made at the expense of the 6th ROK Division. The 358th Regiment of the 120th Division, CCF 40th Army, hurled nearly 2,000 men at the Marine battalion. Charlie Company, commanded by Captain Eugene H. Haffey, took the brunt of the assault.[166]
