Background

On 1 September 1950, the 40th US Division, commanded by Maj. Gen D.H. Hudelson, was called to active duty from its status as the California National Guard Div of Southern California, and subsequently moved to Camp Cook, California, where it conducted the early phases of it's training. On 24 February 1951, the Division was alerted for overseas shipment to Japan and departed from San Francisco at the end of March 1951.

On 10 April 1951, the Division began arriving in Japan and occupied various camps throughout Northern Honshu with the Division Headquarters at Camp Schemmelfenning, near Sendai. Now part of the XVI US Corps, the Division was given the dual mission of defending Northern Honshu and conducting additional training.

On 22 December 1951, the Division was alerted for Korean duty where it was to relieve the 24th US Division. The Division began preparations for a three-echelon movement from Japan, scheduled to start on 7 January 52. The echelons were to be comprised as follows:

  • 1st echelon: 160th Infantry Regiment, 143rd Field Artillery Battalion, 625th Field Artillery Battalion, 40th Division Artillery Headquarters, Battery A, 140th AAA AW Battalion
  • 2nd echelon: Headquarters 40th Division, 223 Infantry Regiment, 980th Field Artillery Battalion, 981st Field Artillery Battalion
  • 3rd echelon: 224th Infantry Regiment, 140th Tank Battalion

January 1952

The Division began the three-echelon movement to Korea on 7 January, as scheduled and by 11 January, the 1st echelon landed at Inchon. The 160th Infantry Regiment departed immediately for the 24th Division sector and completed the relief of the 19th Infantry Regiment on 19 January. With the landing of the 2nd echelon at Inchon on 22 January, the Division became assigned to Eighth US Army and attached to IX US Corps.

By 28 January, the 223rd Infantry Regiment had completed the relief of the 21st Infantry Regiment and the CG, 40th US Division, assumed sector responsibility for the Kumsong-Chwapae-ri sector on the central front. With the passing of sector responsibility, the 6th Tank Battalion and 5th US RCT became attached to the Division. The Division was now deployed with the 223rd Infantry Regiment on the left, the 5th RCT in the center and the 160th Infantry Regiment on the right. Division Artillery was in support. The 224th Infantry Regiment and the 140th Tank Battalion were en route from Japan as the month ended. A tank led, 2 platoon raid by the 5th US RCT, resulting in the destruction of eight enemy bunkers, highlighted the combat activity during the period. Small scale patrol clashes characterized the combat activity, with numerous combat and reconnaissance patrols being dispatched by Division units.

February 1952

The Division maintained it's positions along the stable IX US Corps sector during the month.

The Division was initially deployed as previously reported. On 3 February, the 224th Infantry Regiment and 140th Tank Battalion landed at Inchon and began their movement to the Division sector.  The 140th Tank Battalion immediately began its relief of the 6th Tank Battalion, which was then released from attachment to the Division. On 10 February the 224th Infantry Regiment relieved the 5th US RCT in the center sector, with the 5th US RCT being released from attachment at this time.

With the mission of finding, fixing and destroying the enemy and his works at every opportunity, the Division pursued an aggressive program of patrols, company size combat raids, and tank and artillery attacks on prepared positions. From 10-15 February, the Division participated in Operation Clam Up, which was designed to lure Chinese patrols into ambush through cessation of friendly fire and patrolling, together with the simulation of a withdrawal.

Highlight of the combat activity was a two-phase operation, employing artillery supported armor on 29 February. The first phase was carried out by two companies of the 140th Tank Battalion near Kumsong and resulted in the destruction of six bunkers, the damaging of 36 additional bunkers, and an estimated 24 enemy KIA and 47 WIA.

The second phase was conducted by the 224th Infantry Regimental Tank Company and it resulted in ten enemy bunkers destroyed, eight enemy KIA, twelve estimated KIA and ten estimated WIA.

March 1952

The Division continued to maintain its positions along the Kumsong-Chwapae-ri sector of the central front until 30 March, when it was relieved by the Capitol ROK and 6th ROK Divisions.

The Division was initially deployed with the 223rd Infantry Regiment on the left the 224th Infantry Regiment in the center and the 160th Infantry Regiment on the right. Division Artillery and the 140th Tank Battalion were in support.

The Division continued the program of patrolling so as to maintain contact while inflicting maximum casualties and denying the enemy the opportunity of permanently entrenching himself south of Line Bill, a line parallel to and 1000-3000 yards in front of the MLR. Organic tanks were used effectively in both day and night operations, conducting direct fire missions against enemy positions.

During the period 21-30 March, the Division was relieved by elements of the Capitol ROK and 6th ROK Divisions.  Sector responsibility was assumed by the ROK forces on 30 March.  The Division immediately began a movement to the 2nd ROK Division sector to effect the relief of that unit. The 160th Infantry Regiment completed the relief of the 32nd ROK Regiment and the 223rd Infantry Regiment completed the relief of the 31st ROK Regiment as the period ended.

April 1952

On 1 April the Division completed the relief of the 2nd ROK Division and assumed control of the Kumhwa-Kumsong. The Division was deployed with the 223rd Infantry Regiment on the left, 160th Infantry Regiment on the right and the 224th Infantry Regiment and 140th Tank Battalion in Division reserve. Division Artillery was in support.

On 3 April, a change in boundary between the Division and the 2nd US Division necessitated the deployment of the 224th Infantry Regiment on line to the left of the 223rd Infantry Regiment. This move was completed on 6 April and the Division was now deployed west to east with the 224th Infantry Regiment, 223rd Infantry Regiment and the 160th Infantry Regiment on line. The 140th Tank Battalion remained in division reserve.

Battle lines remained unchanged as the Div constructed and improved positions in the new area, conducted patrols and numerous tank operations against enemy positions, while sustaining several company sized probes by the enemy. On 16 April the 224th Infantry Regiment conducted a reinforced company size operation to seize ground west of the OPLR in order to strengthen sector defenses. The operation was conducted without opposition.

May 1952

The Division remained deployed as previously reported and battle lines remained unchanged during the month.

Due to the marked increase in mortar and artillery fire, an intensified program of bunker building and improvement was conducted to increase the defensive capabilities of the Div and to decrease friendly casualties.

Four company size night patrol actions were conducted with the mission of seizing objectives and destroying enemy personnel and installations to prevent the establishment of positions south of line Bill. All four operations were successful.

On 19 May, IX US Corps revised the Division left boundary to the rear of the MLR and relieved the Division of responsibility for the vital Kumhwa Valley, with such responsibility being placed with the 7th US Division.

June 1952

The improvement and strengthening of defensive positions and the maintenance of enemy contact through patrol activity continued to receive primary consideration by the Division.

Deployment with the 224th Infantry Regiment on the left, the 223rd Infantry Regiment in the center, the 160th Infantry Regiment on the right and the 140th Tank Battalion in reserve, the Division continued this primarily defensive mission along the Kumhwa-Kumsong sector of the central front.

The MLR positions were unchanged until 12 June when the 160th Infantry Regiment occupied the former OPLR in strength, under the cover [sic] of darkness, and with negative enemy contact. The positions were consolidated, giving greatly increased operational capability to the Regt as it enabled it to occupy the sector with two battalions abreast and one in reserve. Combat activity during June was highlighted by several company size night raiding operations with the primary mission of seizing prisoners. The bunker-busting operations continued, employing both tanks and towed 90mm guns along MLR positions. Two tank operations were conducted by units of the 140th Tank Battalion in support of company sized attacks by 6th ROK Division elements against enemy outposts. Three tanks were lost in the latter of these engagements.

The relief of the Div by the 2nd ROK Div was accomplished from 26-28 June. On 30 June, the Division, less Division Artillery and 140th Tank Battalion, closed into FTC #5 to begin a period of training and rehabilitation in conjunction with the mission of IX US Corps reserve. Division Artillery and the 140th Tank Battalion were placed under IX US Corps control to support the 2nd ROK Division.  On 2 June, Brig. Gen. Joseph P. Cleland assumed command of the Division.

July 1952

The Division (-), occupying the position of IX US Corps reserve, continued its activities at FTC #5 until 13 July, at which time it moved to a new training center near Kapyong and resumed training and security missions for the remainder of the period. Initially, the Division units were located as previously reported. Division Artillery and the 140th Tank Battalion remained under IX US Corps control, conducting missions in support of the 2nd ROK Division. On 1 July the 3rd Battalion, 223rd Infantry Regiment, was dispatched to the Sangdong Mine area to perform a security mission. The 224th Infantry Regiment, attached to 2nd Logistical Command on 5 July, left for Pusan to provide security forces for prisoner of war enclosures in that area.

Upon completion of the movement to Kapyong, 13-19 July, the Division resumed an intensive training program, rehabilitated reserve defensive positions on Line Kansas and provided security at IX US Corps Headquarters.  The training program included training of the individual soldier and progressed to small unit tactics which emphasized teamwork. Extensive plans and preparations were made to ready the Division (-) for employment as a blocking or counterattacking force.  On 6 July, Brig. Gen Joseph P. Cleland, CG, was promoted to Major General.  On 31 July Maj. Gen Cleland was temporarily assigned IX US Corps Commander. Brig. Gen. Rogers assumes command of the Division.

August 1952

The Division (-) with Headquarters in the Kapyong area, continued as IX US Corps reserve during the month and conducted training which varied in scope to include tests for battalion Combat teams.

Schools for training specialists were conducted by the Division technical services. Extensive plans and preparations were made to prepare the Division for instant employment as a counterattacking or blocking force should developments necessitate such action.

The 224th Infantry Regiment remained under attachment to 2nd Logistical Command. Division Artillery and the 140th Tank Battalion were under the operational control of 2nd ROK Division with the mission of direct support. The 160th and 223rd Infantry Regiments conducted training programs, rehabilitated reserve defensive positions on Line Kansas and provided security for the Sangdong Mine area and IX US Corps Headquarters. On 9 August, Maj. Gen. Cleland assumed command of the Division, relieving General Rogers.

September [sic] 1952

The Division remained in IX US Corps reserve, continuing to conduct training and the rehabilitation of defensive positions on Line Kansas, while performing various security missions.

Division Artillery and 140th Tank Battalion continued under IX US Corps control operating in direct support of the 2nd ROK Division. On 23 September, the 224th Infantry Regiment was relieved from its guard mission and rejoined the Division. The 160th Infantry Regiment and 223rd Infantry Regiment participated in battalion-size combat firing exercises.

October [sic] 1952

During the first half of October, the Division (-) continued to occupy a position as IX US Corps reserve in the Kapyong area, where it performed training and security missions.

On 16 October, the Division was ordered to relieve the 25th US Division in the Paem-ihyon-ni sector. On 21st October, Division Artillery and the 140th Tank Battalion were released from IX US Corps control. By 22 October the 224th Infantry Regiment and the 160th Infantry Regiment had relieved the 27th Infantry Regiment and the 14th Infantry Regiment, respectively, and the CG, 40th US Division assumed sector responsibility. The Division then passed to X Corps control and the 5th US RCT was attached. The Division was deployed with the 160th Infantry Regiment on the left, the 224th Infantry Regiment in the center and the 5th US RCT on the right. The 223rd Infantry Regiment arrived a day later and acted as the Division reserve. On 31 October, the 5th US RCT moved to Division reserve positions after being relieved by the 223rd Infantry Regiment Division Artillery and the 140th Tank Battalion were in support.

The Division performed a defensive mission, maintaining enemy contact by aggressive patrol activity. Combat was highlighted by a series of enemy attacks which ranged from platoon (+) to battalion (-) in size. Heavy casualties were inflicted on the enemy and the MLR was firmly in friendly hands at the close of the period.

26 October: Early in the morning, an estimated enemy battalion (-), supported by heavy artillery and mortar fire, attacked the positions of Companies F and G, 160th Infantry Regiment, in the Heartbreak Ridge area. During the 1 hour and 20 minute firefight which followed, the enemy advanced to within 35 yards of friendly positions before being forced to withdraw with an estimated 20 KIA and 40 WIA.

November 1952

The Division, with CP at Tokkol-li, was firmly entrenched in the center of the X US Corps sector, deployed with the 160th Infantry Regiment on the left, the 224th Infantry Regiment in the center, the 223rd Infantry Regiment on the right and the 5th US RCT in reserve. The sector, in most respects, was static during this period.  Continued emphasis was placed on the construction and improvement of defensive positions, as the enemy held the sectors dominating terrain.

Numerous small-unit actions and night patrols characterized the combat activity during the month. Tanks continued their heavy direct fire destruction of enemy installations. One battalion size attack was made on Heartbreak Ridge, 3-4 November, in which the enemy lost 131 KIA and had 450 estimated WIA. Seven prisoners were taken.

Battle casualties for November - 287

December 1952

The Division continued to occupy the center of the X US CORPS sector during this period. The Division retained its defense mission along a static front, and limited it's operations to aggressive patrol activity, the development of defensive positions, and the continued training of the reserve regiment. The Division remained deployed as previously reported. Patrol activity showed a definite trend toward fewer, but larger and better organized patrols, using earlier and closer fire support. Ambush patrols, as well as combat and reconnaissance patrols, were fully utilized.  Construction and repairs of defensive positions progressed, with first priority on the MLR given to works on wire, trenches and bunkers.

Battle casualties for December - 163

January 1953

The Division CP at Tokkol-li continued to defend its sector on Line Minnesota until relieved by the 45th US Division late in the month. Normal combat operations were conducted and positions improved despite sub-zero temperatures.

The Div was initially deployed as previously reported. On 8 January, the 5th US RCT relieved the 223rd Infantry Regiment, which then moved to Division reserve.

The relief of the Division by the 45th US Division, began on January 28 when the 224th Infantry Regiment was relieved by the 180th Infantry Regiment. On 30 January the 160th Infantry Regiment was relieved by the 279th Infantry Regiment and the CG, 45th US Division, assumed sector responsibility. On 31 January, the relief was completed when the 223rd Infantry Regiment was relieved by the 179th Infantry Regiment. Division Artillery remained in position and passed to operational control of the 45th US Division, while the 140th Tank Battalion remained on line and was attached to the same division.

As the month ended, the Division, with its CP at Nambakchon, was occupying the position of X US Corps reserve, with the 160th Infantry Regiment at Hwachon, 223rd Infantry Regiment at Kowantong and the 224th Infantry Regiment at Imje.

Combat activity during the period consisted of an increasing number of patrol engagements and enemy probes of the MLR. The largest of these occurred in the early morning of 28 January when an estimated 100 enemy attacked MLR positions of Company G, 5th US RCT, in the Punchbowl area. The enemy succeeded in penetrating the MLR to a depth of 20 yards before being ejected.

Battle casualties in January - 191

February 1953

The Division retained its assignment as X US Corps reserve and performed a two-fold tactical mission; to be prepared for employment as a counter-attacking force in any part of X US Corps area, and to provide fire support to the 12th ROK Division.

The regiments remained deployed as previously reported. On 3 February, Division Artillery, under X US Corps control, completed the relief of the 45th Division Artillery in the 12th ROK Division sector and assumed a mission in direct support of the 12th ROK Division. On 11 February the 140th Tank Battalion began the relief of the 245th Tank Battalion on MLR positions in the 12th ROK Division sector and began missions in direct support of the 12th ROK Division while under parent unit control. A task force from the 160th Infantry Regiment accepted responsibility for the security of the Sangdong Mine area on 17 February.

During the period, the major effort was directed towards training and rehabilitation. The Division training program, inaugurated on 9 February, stressed weapons, small unit tactics, and physical training. Plans were formulated and construction was started on a semi-permanent Division training center.

March 1953

The Division, as Eighth US Army and X US Corps reserve, pointed its major efforts toward full preparedness for counter-attacking or blocking missions and a training program gauged to maintain 100 percent combat effectiveness. The Division also had the task of giving tank and artillery support to ROK units.

The Division CP remained at Nambakchon, with the regiments located as previously reported. Division Artillery remained under X US Corps control and supported the 12th ROK Division. The 140th Tank Battalion maintained MLR positions and supported both the 7th and 12th ROK Divisions.

Tactical units conducted training exercises at platoon and company level. the most extensive training operation conducted during the period was Trainer One, the purpose of which was to test the ability of the 160th Infantry Regiment and Division Headquarters (-) to move from X US Corps to execute the IX US Corps attack plan, Hooker One, in the Chorwon sector. The operations started on 21 March, involved a move of about 135 miles and proved very beneficial to those partaking.

6-28 March: The Division was designated Eighth US Army reserve.

17 March: The 224th Infantry Regiment attached to 45th US Division and moved to Wondang-ni where it took up 45th Division reserve positions.

April 1953

The Division, during most of April, remained in X US Corps reserve, in position to reinforce either the 12th ROK Division or the 45th US Division. Training and rehabilitation continued. Late in the month, the Division effected the relief of the 20th ROK Division and returned to defend the northern rim of the Punchbowl on Line Minnesota (MLR).

The Division, with CP at Nambakcho-ni, underwent a series of movements during the period. The 224th Infantry Regiment, remaining under operational control of the 45th US Division from the preceding month, relieved the 5th US RCT on line on 14 April in that Division's sector. On 19 April, the 160th Infantry Regiment was also placed under operational control of the 45th US Division and relieved the 279th Infantry Regiment as 45th US Division reserve.

The 223rd Infantry Regiment initiated the relief of the 20th ROK Division by the Division when it relieved the 61st ROK Regiment on line on 26 April. On 27 April the 224th Infantry Regiment and the 40th Division Artillery (-) returned to Division control and the CG accepted sector responsibility from the 20th ROK Division at that time. The 160th Infantry Regiment passed from 45th US Division control to X US Corps control at this time and occupied reserve positions. Division Artillery, previously supporting the 12th ROK Division, left two Field Artillery battalions in the 12th ROK Division sector. The 140th Tank Battalion continued it's support of the 12th ROK Division with two tank companies during the entire month.

As April ended, the Division was deployed across the Ihyon-ni-Kalbakumi sector with the 223rd Infantry Regiment on the right, the 224th Infantry Regiment on the left and the 160th Infantry Regiment under operational control of X US Corps, in reserve. The 143rd Field Artillery Battalion, the 981st Field Artillery Battalion under X US Corps control, and the 140th Tank Battalion remained in support of the 12th ROK Division. On 17 April, Maj.

The Division was engaged in combat during the entire period with numerous small-scale patrol clashes characteristic of the action.

Operation Try-out was conducted on 9 May with the mission of determining the efficiency with which front line units could be issued gas masks.

June 1953

The Division continued to occupy its previously reported positions in the Punchbowl sector. The main effort was directed toward strengthening the MLR, with emphasis placed on improving the trench system. A program of relocation of crew served automatic weapons was carried out with the view of assuring that the most likely avenues of approach were covered to the maximum extent with grazing fire. The Division remained deployed as reported at the close of the previous period.

Extensive patrol activity, employing both reconnaissance and ambush patrols, was characteristic of normal combat activity during the period. In all, 94 patrols were dispatched in the Division sector.

Combat activity was highlighted by an attack on friendly positions on the night of 2 June. Following an exceptionally heavy concentration of mortar and artillery fire, an enemy force of 40-50 men attacked MLR positions of the 223rd Infantry Regiment in the vicinity of DT2341. After 30 minutes of hand-to-hand combat, the enemy was forced to withdraw. Enemy casualties were 17 KIA, 5 estimated WIA and one prisoner of war.

July 1953

The Division continued to occupy defensive positions in the Punchbowl sector until 10 July, when it was relieved by the 20th ROK Division. On 11 July the Division relieved the 45th US Division in the Heartbreak Ridge/Sandbag Castle sector, which extended from PAEAM to a point west of Inyon-ni. The Division remained in this area until 27 July when the cease-fire occurred and the Division prepared to withdraw to the post-armistice main battle position.

While in the Punchbowl sector, the Division was deployed with the 223rd Infantry Regiment on the right and the 224th Infantry Regiment on the left. On the Heartbreak Ridge/Sandbag Castle area, the 223rd Infantry Regiment was on Heartbreak Ridge, to the left, while the 224th Infantry Regiment was in the Sandbag Castle sector, to the right. The 160th Infantry Regiment continued its mission, under KCOMZ control, of guarding prisoners of war on Koje-do until 20 July. On that date, the 160th Infantry Regiment disembarked at Sokcho-ri and moved to the vicinity of Inje, where it passed to operational control of X US Corps as Corps reserve. Division Artillery (-) continued support of the Division during the month. The 143rd Field Artillery Battalion remained under X US Corps control in support of the 12th ROK Division.

Patrol activity continued during the month. The last significant action of a combat nature took place on 27 July when the enemy shelled friendly positions for four hours with 4700 rounds of mortar and artillery.
