A. Record of Events

BACKGROUND: A National Guard Div from Oklahoma, the 45th US Div was called into active service on 1 Sep 1950. It received fillers and began an intensive training program on 6 Nov 1950 at Camp Polk, LA. Under the command of Brig Gen James C. Styron since activation, the Div arrived overseas in April 1951 with the dual mission of providing security for Hokkaido, Japan, and completing its training. On 18 Nov, the Div was alerted for movement to Korea. The Regts of the Div moved to Korea as follows:

180th Inf Regt 5 Dec

179th Inf Regt 17 Dec

279th Inf Regt 28 Dec

As of 17 Dec 1951, the Div was assigned to Eighth US Army. On 18 Dec, it was attached to I US Corps. By 23 Dec, the Div assumed responsibility for a sector of Line Jamestown (MLR), formerly held by the 3d US Div. As 1951 ended, all elements of the Div were in Korea in a combat status and the Div was performing its mission of defending its sector of Line Jackson (MLR).

January 1952: The Div, Command Post at Taegwang-ni, occupied, defended, and improved positions in the relatively static I US Corps sector of Line Jamestown (MLR). Sector responsibility extended from Omgogae to Noltari. The Div was deployed with the 180th Inf Regt on the right, flanking the 9th ROK Div, and the 179th Inf Regt on the left, flanked by the 3d US Div. The 279th Inf Regt was in div reserve. On 15 Jan, the 279th Inf Regt relieved the 180th Inf Regt, which then reverted to div reserve. Div Artillery supported the Div throughout the month. The 245th Tank Battalion remained in div reserve, but was physically located in the sector of the 9th ROK Div, blocking the most likely avenue of approach for enemy armor.

Throughout the period, ambush and reconnaissance patrols were extremely active. Three major raids were conducted by elements of the 179th and 180th Regts against strong enemy positions in the Hill 223 and Hill 290 areas. Despite bitter resistance, friendly forces succeeded in inflicting heavy casualties upon the enemy. The remainder of the combat activity centered about artillery fire placed on known and suspected enemy positions and personnel.

Battle casualties for January - 156.

February 1952: The Div continued its mission of occupying, defending, and improving its positions along Line Jamestown (MLR).

The Div was deployed with the 179th Inf Regt on the left, 279th Inf Regt on the right, and the 180th Inf Regt in reserve. On 6 Feb, the 179th Inf Regt was relieved by the 180th Inf Regt. On 27 Feb, the 279th Inf Regt was relieved by the 179th Inf Regt, which then reverted to div reserve positions. The 245th Tank Battalion remained in reserve positions in the 9th ROK Div sector covering enemy armor approaches. Div Artillery remained in support.

From 10-16 Feb, during Operation Snatch, all personnel remained out of sight and all weapons were silenced to simulate a friendly withdrawal and deceive the enemy into exposing himself. Initially successful, the plan's effort was materially lessened by alertness of enemy intelligence agencies in securing information as to friendly intentions.

Constant contact with the enemy was maintained by an aggressive and continuous patrol program. Several raids were conducted by friendly forces.

Friendly patrols, during the month, destroyed 9 enemy bunkers, 43 buildings in enemy territory, and damaged 16 other enemy buildings and 1 outpost.

Battle casualties for February - 43.

March 1952: The Div retained its defensive mission as it occupied its previously reported positions. The combat situation remained static.

The Div was deployed with the 180th Inf Regt on the left, the 179th Inf Regt on the right, and the 279th Inf Regt in reserve. On 17 Mar the 180th Inf Regt was relieved by the 279th Inf Regt and reverted to reserve positions.

The 245th Tank Battalion, physically located in the sector of the 9th ROK Div, remained as part of div reserve, with one company in direct support of the 9th ROK Div. Div Artillery remained in support of the Div during Mar.

During the relief from 15-17 Mar, both regts and their supporting artillery battalions implemented Operation Rehearse, involving movements from secondary defensive lines, Wyoming and Consolidate to Line Jamestown (MLR) under a simulated tactical situation. Due to restrictions imposed by higher Hq, no large raids were conducted. The Div maintained an active defensive role, keeping contact with the enemy by aggressive operation of patrols. Ambuscades and listening posts were maintained nightly.

On 22 Mar, an outpost in the 179th Inf Regimental sector was probed and partially overrun by an estimated enemy company. Other elements from the 179th Inf Regt counterattacked, reoccupied, and secured the position. Enemy had 31 KIA, 1 POW.

Battle casualties for March - 72.

April 1952: The Div continued to defend its assigned sector on Line Jamestown (MLR). Battle positions remained unchanged along the static front.

The 279th Inf Regt occupied the left sector of the Div front, while the 179th Inf Regt occupied the right sector. On 9 Apr, the 179th Inf Regt was relieved by the 180th Inf Regt, which had been in div reserve. On 11 Apr, the 20th Philippine Inf Battalion became attached to the Div and further attached to the 179th Inf Regt. On 28 Apr, the 179th Inf Regt relieved the 279th Inf Regt and assumed responsibility for the left sector. Div Artillery supported the Div throughout the month, and the 245th Tank Battalion remained in reserve. While each inf regt was in div reserve, it implemented on Operation Rehearse.

Due to restrictions imposed by higher Hq, no large raids were conducted. The Div maintained an active defense role, keeping contact with the enemy by aggressive operation of patrols ranging in size to reinforced platoons. One company-sized sweep per week was made in the Div sector.

The 245th Tank Battalion remained in reserve positions. The 1st ROK Div was on the left flank, and the 9th ROK Div remained on the right flank.

Although the enemy exhibited a more aggressive attitude and employed artillery in increasing amounts, the combat situation in the Div sector remained static.

The Div maintained an active defense, keeping contact with the enemy by aggressive patrol actions. The enemy strongly resisted friendly patrols, and displayed a great deal of aggressiveness in small scale attacks on friendly outposts.

18-21 May: Combat patrols from 20th Philippine Inf Battalion raided Outpost Eerie. Elements of this unit, in five attempts, twice reached the tactical barbed wire surrounding the objective. Six enemy bunkers were destroyed, 7 bunkers damaged, 71 enemy KIA, 10 WIA. Friendly had 10 WIA, 1 MIA.

Action increased sharply, and the need to strengthen the OPLR was clearly indicated. Div forces seized and occupied a series of selected terrain features, in Operation Counter, the possession of which provided an adequate OPLR. Enemy forces reacted violently, particularly in the left sector at Outpost Eerie, with company to regimental size attacks in addition to numerous smaller engagements. By 14 June, the desired OPLR was established.

4-12 June: First phase, Operation Counter, conducted with elements of 180th and 279th Inf Regts occupying 10 outpost objectives.
