A.RECORD OF EVENTS:
BACKGROUND: On 1 Sep 50, the 40th US Div, 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 Feb 51, the Div was alerted for overseas shipment to Japan and departed from San Francisco at the end of Mar 51.
On 10 Apr 51, the Div began arriving in Japan and occupied various camps throughout Northern HONSHU with the Div Hq at Camp Schemmelfenning, near SENDAI. Now part of the XVI US Corps, the Div was given the dual mission of defending Northern HONSHU and conducting additional training.
On 22 Dec 51, the Div was alerted for Korean duty where it was to relieve the 24th US Div. The Division began preparations for a 3-echelon movement from Japan, scheduled to start on 7 Jan 52. The echelons were to be comprised as follows:
1st echelon: 160th Inf Regt, 143rd FA Bn, 625th FA Bn, 40th Div Arty Hq, Btry A, 140th AAA AW Bn.
2nd echelon: HQ 40th Div, 223 Inf Regt, 980th FA Bn, 981st FA Bn.
3rd echelon: 224th Inf Regt, 140th Tk Bn.

JANUARY 1952: The Div began the 3 echelon movement to Korea on 7 Jan, as scheduled and by 11 Jan, the 1st echelon landed at INCHON. The 160th Inf Regt departed immediately for the 24th Div sector and completed the relief of the 19th Inf Regt on 19 Jan. With the landing of the 2nd echelon at INCHON on 22 Jan, the Div became assigned to Eighth US Army and attached to IX US Corps.
By 28 Jan, the 223rd Inf Regt had completed the relief of the 21st Inf Regt and the CG, 40th US Div, assumed sector respons- ibility for the KUMSONG- CHWAPAE-RI sector on the central front. With the passing of sector responsibility, the 6th Tk Bn and 5th US RCT became attached to the Div. The Div was now deployed with the 223rd Inf Regt on the left, the 5th RCT in the center and the 160th Inf Regt on the right. Div Arty was in support. The 224th Inf Regt and the 140th Tk Bn were enroute from Japan as the month ended. A tank led, 2 platoon raid by the 5th US RCT, resulting in the destructin of 8 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 Div units.
FEBRUARY 1952: The Div maintained it's positions along the stable IX US Corps sector during the month.
The Div was initially deployed as previously reported. On 3 Feb, the 224th Inf Regt and 140th Tk Bn landed at INCHON and began their movement to the Div sector.The 140th Tk Bn immediately began it's relief of the 6th Tk Bn, which was then released from atchmt to the Div. On 10 Feb the 224th Inf Regt relieved the 5th US RCT in the center sector, with the 5th US RCT being released from atchmt at this time.
With the mission of finding, fixing and destroying the enemy and his works at every opportunity, the Div pursued an aggressive program of patrols, company size combat raids, and tank and artillery attacks on prepared positions. From 10 - 15 Feb, the Div 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,em- ploying artillery supported armor on 29 Feb. The first phase was carried out by two companies of the 140th Tk Bn near KUMSONG and resulted in the destruction of 6 bunkers, the damaging of 36 additional bunkers and an estimated 24 enemy KIA, 47 WIA.
The second phase was conducted by the 224th Inf Regt'l Tk Co and it resulted in 10 enemy bunkers destroyed, 8 enemy KIA, 12 est- imated KIA and 10 estimated WIA.

MARCH 1952: The Div continued to maintain it's positions along the KUMSONG - CHWAPAE-RI sector of the central front until 30 Mar when it was relieved by the Capitol ROK and 6th ROK Divs.
The Div was initially deployed with the 223rd Inf Regt on the left the 224th Inf Regt in the center and the 160th Inf Regt on the right. Div Arty and the 140th Tk Bn were in support.
The Div 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 oper- ations, conducting direct fire missions against enemy positions.
During the period 21 - 30 Mar the Div was relieved by elements of the Capitol ROK and 6th ROK Divs.Sector responsibility was assumed by the ROK forces on 30 Mar.The Div immediately began a movement to the 2nd ROK Div sector to effect the relief of that unit. The 160th Inf Regt completed the relief of the 32nd ROK Regt and the 223rd Inf Regt completed the relief of the 31st ROK Regt as the period ended.
APRIL 1952: On 1 Apr the Div completed the relief of the 2nd ROK Div and assumed control of the KUMHWA - KUMSONG sector. The DIV was deployed with the 223rd Inf Regt on the left, 160th Inf Regt on the right and the 224th Inf regt and 140th Tk Bn in DIV reserve. Div Arty was in support.
On 3 Apr, a change in boundary between the Div and the 2nd US Div necessitated the deployment of the 224th Inf Regt on line to the left of the 223rd Inf Regt. This move was completed on 6 Apr and the Div was now deployed west to east with the 224th Inf Regt, 223rd Inf Regt and the 160th Inf Regt on line. The 140th Tk Bn remained in div 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 Apr the 224th Inf Regt 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 Div remained deployed as previously reported and battle lines remained unchanged during the month.
Due to the marked increase in mortar and artillery fire, an in- tensified program of bunker building and improvement was conducted to increase the defensive capabilities of the Div and to decrease friendly casualties.
( 4 ) 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 Div left boundary to the rear of the MLR and relieved the Div of responsibility for the vital KUMHWA Valley, with such responsibility being placed with the 7th US Div.
June 1952: The improvement and strengthening of defensive positions and the maintenance of enemy contact through patrol activity con- tinued to receive primary consideration by the Div.
Deployment with the 224th Inf Regt on the left, the 223rd inf Regt in the center, the 160th Inf Regt on the right and the 140th Tk Bn in reserve, the Div 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 Inf Regt 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 Jun 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 Tk Bn in support of company sized attacks by 6th ROK Div 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 Jun. On 30 Jun, the Div, less div Arty and 140th Tk Bn, closed into FTC # 5 to begin a period of training and rehabil- itation in conjunction with the mission of IX US Corps reserve. Div Arty and the 140th Tk Bn were placed under IX US Corps control to support the 2nd ROK Div.
2 Jun: Brig Gen Joseph P. Cleland assumed command of the Div on 2 Jun.
July 1952: The Div (-), occupying the position of IX US Corps reserve, continued it's activities at FTC # 5 until 13 Jul,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 Div units were located as previously reported. Div Arty and the 140th Tk Bn remained under IX US Corps control, conducting missions in support of the 2nd ROK Div. ( 5 ) On 1 Jul the 3rd Bn, 223rd Inf Regt, was dispatched to the SANGDONG Mine area to perform a security mission. The 224th Inf Regt, attached to 2nd Log Comd on 5 Jul, left for Pusan to provide security forces for PW enclosures in that area.
Upon completion of the movement to KAPYONG, 13 - 19 Jul, the Div resumed an intensive training program, rehabilitated reserve defensive positions on Line KANSAS and provided security at IX US Corps Hq.
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 Div (-) for employment as a blocking or counterattacking force.
6 Jul: Brig Gen Joseph P. Cleland, CG, promoted to Maj Gen.
31 Jul Maj Gen Cleland temporarily assigned IX US Corps Commander. Brig Gen Rogers assumes command of the Div.
August 1952: The Div (-) with Hq 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 Div tech- nical services. Extensive plans and preparations were made to prepare the Div for instant employment as a counterattacking or blocking force should developments necessitate such action.
The 224th Inf Regt remained under attachment to 2nd Log Comd. Div Arty and the 140th Tk Bn were under the operational control of 2nd ROK Div with the mission of direct support. The 160th and 223rd Inf Regts conducted training programs, rehabilitated reserve defensive positions on Line KANSAS and provided security for the SANGDONG Mine area and IX US CORPS Hq's.
9 August: Maj Gen Cleland assumed command of the Div, relieving Gen Rogers.
SEPTEMBER (sic) 1952: The Div remained in IX US Corps reserve, continuing to conduct training and the rehabilitation of defensive positions on Line KANSAS, while performing various security missions.

The 160th Inf Regt and 223rd Inf Regt participated in battalion size combat firing exercises.
( 6 ) OCTOBER (sic) 1952: During the first half of Oct, the Div (-) continued to occupy a position as IX US Corps reserve in the KAPYONG area, where it performed training and security missions.
On 16 Oct, the Div was ordered to relieve the 25th US Div in the PAEM-IHYON-NI sector. On 21st Oct, Div Arty and the 140th Tk Bn were released from IX US Corps control. By 22 Oct the 224th Inf Regt and the 160th Inf Regt had relieved the 27th Inf Regt and the 14th inf Regt respectively and the CG, 40th US Div assumed sector responsibility. The Div then passed to X Corps control and the 5th US RCT was attached. The Div was deployed with the 160 th Inf Regt on the left, the 224th Inf Regt in the center and the 5th US RCT on the right. The 223rd Inf Regt arrived a day later and acted as the Div reserve. On 31 October, the 5th US RCT moved to Div reserve positions after being relieved by the 223rd Inf Regt. Div Arty and the 140th Tk Bn were in support.
The Div 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 Oct: early in the morning, an estimated enemy battalion (-), supported by heavy artillery and mortar fire, attacked the pos- itions of Cos F and G, 160th Inf Regt, 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 Div, with CP at TOKKOL-LI, was firmly entrenched in the center of the X US Corps sector, deployed with the 160th Inf Regt on the left, the 224th Inf Regt in the center, the 223rd Inf Regt 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 Nov, in which the enemy lost 131 KIA and had 450 estimated WIA. Seven prisoners were taken.
Battle casualties for November - 287
DECEMBER 1952: The Div continued to occupy the center of the X US CORPS sector during this period. The Div retained it's 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 regt. The Div 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.
( 7 ) 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 Div, CP at TOKKOL-LI, continued to defend it's sector on Line MINNESOTA until relieved by the 45th US Div 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 Jan, the 5th US RCT relieved the 223rd Inf Regt, which then moved to Div reserve.
The relief of the Div by the 45th US Div, began on Jan 28 when the 224th Inf Regt was relieved by the 180th Inf Regt. On 30 Jan the 160th Inf Regt was relieved by the 279th Inf Regt and the CG, 45th US Div, assumed sector responsibility. On 31 Jan, the relief was completed when the 223rd Inf Regt was relieved by the 179th Inf Regt. Div Arty remained in position and passed to operational con- trol of the 45th US Div, while the 140th Tk Bn remained on line and was attached to the same div.
As the month ended, the Div, with it's CP at NAMBAKCHON, was occupying the position of X US Corps reserve, with the 160th Inf Regt at HWACHON, 223rd Inf Regt at KOWANTONG and the 224th Inf REGT 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 Jan when an estimated 100 enemy attacked MLR positions of Co 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 Div retained it's 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 Div.
The Regts remained deployed as previously reported. On 3 Feb, Div Arty, under X US Corps control, completed the relief of the 45th Div Arty in the 12th ROK Div sector and assumed a mission in direct support of the 12th ROK Div. On 11 Feb the 140th Tk Bn began the relief of the 245th Tk Bn on MLR positions in the 12th ROK Div sector and began missions in direct support of the 12th ROK Div while under parent unit control. A task force from the 160th Inf Regt accepted responsibility for the security of the SANGDONG Mine area on 17 Feb.
During the period, the major effort was directed towards training and rehabilitation. The Div training program, inaugurated on 9 Feb, stressed weapons, small unit tactics, and physical training. Plans were formulated and construction was started on a semi-permanent Div training center.
( 8 ) MARCH 1953:The Div, 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 guaged to maintain 100 % combat effectiveness. The Div also had the task of giving tank and artillery support to ROK units.
The Div CP remained at NAMBAKCHON, with the Regts located as pre- viously reported. Div Arty remained under X US Corps control and supported the 12th ROK Div. The 140th Tk Bn maintained MLR pos- itions and supported both the 7th and 12th ROK Divs.
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 Inf Regt and Div Hq (-) 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 Mar, involved a move of about 135 miles and proved very beneficial to those partaking.
6-28 Mar: The Div designated Eighth US Army reserve.
17 Mar: The 224th Inf Regt attached to 45th US Div and moved to WONDANG-NI where it took up 45th Div reserve positions.
APRIL 1953: The Div, during most of Apr, remained in X US Corps reserve, in position to reinforce either the 12th ROK Div or the 45th US Div. Training and rehabilitation continued. Late in the month, the Div effected the relief of the 20th ROK Div and returned to defend the northern rim of the PUNCHBOWL on Line MINNESOTA (MLR).
The Div, with CP at NAMBAKCHO-NI, underwent a series of movements during the period. The 224th Inf Regt, remaining under operational control of the 45th US Div from the preceding month, relieved the 5th US RCT on line on 14 Apr in that Divs sector. On 19 Apr, the 160th Inf Regt was also placed under operational control of the 45th US Div and relieved the 279th Inf Regt as 45th US Div reserve.
The 223rd Inf Regt initiated the relief of the 20th ROK Div by the Div when it relieved the 61st ROK Regt on line on 26 Apr. On 27 Apr the 224th Inf Regt and the 40th Div Arty (-) returned to Div control and the CG accepted sector responsibility from the 20th ROK Div at that time. The 160th Inf Regt passed from 45th US Div control to X US Corps control at this time and occupied reserve positions. Div Arty, previously supporting the 12th ROK Div, left two FA battalions in the 12th ROK Div sector. The 140th Tk Bn continued it's support of the 12th ROK Div with two tank companies during the entire month.
As Apr ended, the Div was deployed across the IHYON-NI-KALBAKUMI sector with the 223rd Inf Regt on the right, the 224th Inf Regt on the left and the 160th Inf Regt under operational control of X US Corps, in reserve. The 143rd FA Bn, the 981st FA Bn under X US Corps control, and the 140th Tk Bn remained in support of the 12th ROK Div. On 17 Apr, Maj Gen Gaither assumed command of the Div.

The Div was deployed with the 224th Inf Regt on the left and the 223rd inf Regt on the right. The 160th Inf Regt was under X US Corps control as Corps reserve. On 27 May, the 160th Inf Regt was placed under KCOMZ control with the mission of guarding PW en- closures on KOJE-DO. Div Arty (-) supported the Div. The 140th Tk Bn supported the 12th ROK Div with two companies, while the 143rd FA Bn, still underX US Corps control, remained in support of the 12th ROK Div during the month. On 7 May, the 981st FA Bn reverted to Div Control.
The Div 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 deter- mining the efficiency with which front line units could be issued gas masks.
JUNE 1953: The Div continued to occupy it's 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 Div remained deployed as reported at the close of the previous period.
Extensive patrol activity,employing both reconnaisance and ambush patrols, was characteristic of normal combat activity during the period. In all, 94 patrols were dispatched in the Div sector.
Combat activity was highlighted by an attack on friendly positions on the night of 2 Jun. Following an exceptionally heavy concentration of mortar and artillery fire, an enemy force of 40-50 men attacked MLR positions of the 223rd Inf Regt 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 1 PW.
JULY 1953: The Div continued to occupy defensive positions in the PUNCHBOWL sector until 10 Jul, when it was relieved by the 20th ROK Div. On 11 Jul the Div relieved the 45th US Div in the HEART- BREAK RIDGE SANDBAG CASTLE sector, which extended from PAEAM to a point west of INYON-NI. The Div remained in this area until 27 July when the cease-fire occurred and the Div prepared to withdraw to the Post Armistice Main Battle Position.
( 10 ) While in the PUNCHBOWL sector, the div was deployed with the 223rd Inf Regt on the right and the 224th Inf Regt on the left. On the HEARTBREAK RIDGE - SANDBAG CASTLE area, the 223rd Inf Regt was on HEARTBREAK RIDGE, to the left, while the 224th Inf Regt was in the SANDBAG CASTLE sector, to the right. The 160th Inf Regt continued it's mission, under KCOMZ control, of guarding PWs on KOJE-DO until 20 Jul. On that date, the 160th Inf Regt disembarked at SOKCHO-RI and moved to the vicinity of INJE, where it passed to operational control of X US Corps as Corps reserve. Div Arty (-) continued support of the Div during the month. The 143rd FA Bn remained under X US Corps control in support of the 12th ROK Div.
Patrol activity continued during the month. The last significant action of a combat nature took place on 27 Jul when the enemy shelled friendly positions for four hours with 4700 rounds of mortar and artillery.
