The Korean War MMP

June 26-28 1950


The unsuspecting ROK situated in Seoul

Successful close air support and one artillery barrage. (Two failed arty barrages). The 4th Infantry Division was quite successful and captured the villages of Tongduch’on and Uijongbu with negligible losses. On the western coast, the 5th Infantry destroyed the ROK infantry regiment with little loss, and thus opened the way for the 17th Motorcycle Regiment to probe into the village Kangnung. The NKA’s 6th Infantry Division was the real failure. Although the corps artillery successfully hit the enemy target, the commander of the 6th Infantry could not get his attack together and was consequently repulsed. These things happen.


North Korean 4th and 105th Divisions have crossed the 38th Parallel

The ROK I Corps pulled out of Seoul and relocated in the village of Ch’onan. The ROK 12th Infantry Regiment managed to extricate itself from the front line encounter with the NKA. It aborted its movement in Munsan’ni. The ROK used its limited trucks to transport supply, which would surely be lost on the front lines back to Umsong. The railroad was used to pull the I Corps Artillery out of Seoul and back to HQ in Ch’onan. The 12th Regiment was also re-supplied.

June 29-30 1950

The weather continued clear an allowed flight. The NKA continued to take over key defensive locations with the first goal of taking Seoul. The 4th Division’s artillery managed to disorganize the ROK infantry in the northwestern sector of Seoul. In subsequent fighting, both sides took heavy casualties but that sector of the city fell to the North Koreans. An air barrage was unsuccessful against the 12th Regiment, which was in retreat. The NKA attacked nonetheless and destroyed the infantry unit. Meanwhile, the NKA 5th Infantry Division on the western coast solidified its position in the village of Kangnung. The 109th Tank battalion managed to cross the Han River to the west of Seoul.


The ROK troops in Seoul come under heavy fire

Task Force Smith was sent to Pusan as reinforcements and then immediately moved to the ROK 1st Corps HQ. Remnants of the ROK infantry attempted to hastily assemble a position based on the Han River, but it looked rather feeble.

July 1-4 1950

The wrenches could be heard at the airbase in Pyongyang as the IL-2’s and Yak’s were refitted. The 15th Infantry Regiment was rebuilt in Pyongyang and was slated to return to the 6th Division. The 4th Infantry Division led an attack against the Capital Division in Seoul. The 109th Tank battalion had performed an end run around the city to the southern side and cut off the possible retreat path. The GHQ artillery was successful in its barrage against the enemy troops. In the end the ROK lost the 17th Infantry Regiment in exchange for the NKA’s 16th Infantry Regiment. The southern part of the city was captured along with a ton or so of supply.

The US 34th Infantry Regiment embarked abort ships in Japan headed for the port in Pusan and the ROK received the aid of a couple of squadrons of fighter-bombers and transports. The 1st Regiment of the Capital Division was rebuilt in Pusan. The ROK continued to fall back toward Pusan, while the last of the infantry in Seoul prepared for a rough week ahead. Some supply was salvaged by ROK transports and moved back toward the interior lines. Two squadrons of F-51’s and F-80’s were ordered to attack the NKA airbase at Pyongyang. The attack was a success and resulted in heavy damage to the enemy facilities there. Additionally, a number of the North Koreans’ YAK fighters were destroyed on the ground.

July 5-7 1950

The two fighter squadrons at Pusan were refitted. The US 21st Regiment along with 24th Division’s artillery unloaded at the Pusan port facilities with some additional supply. The 17th Regiment of the Capital Division was rebuilt in Pusan. UN 24th Diviison fueled the 34th Regiment and drove it to the village Y’onch’on. The ROK continued to fall back to the south, which seemed to be running out of land. The ROK 17th Regiment marched to the port at Masan.

The North Korean 7th Infantry Division appeared in P’yongyang as reinforcements. The 16th Infantry Regiment was rebuilt at the supply station in P’yongyang. The GHQ artillery opened fire on the remaining ROK troops in the western part of Seoul. The ROK 15th Infantry Regiment was all but eliminated in the hail of artillery fire. The artillery was followed up by an attack NKA 1st Infantry Division led by the 13th Regiment from the 6th Division. The ROK was completely wiped out and Seoul fell to the North Korean Army. Afterward, the 105th Tank sent the 107th Battalion south and it captured the airbase at P’yongt’aek.


Seoul falls to the North Koreans

July 8-11 1950

The US 27th Infantry Regiment embarked on transport ships in Japan and sailed to the port of Pusan. US 21st Infantry Regiment fueled and advanced to Y’onch’on. The US 8th Army HQ also arrived in Pusan from Japan. The UN Airforce sent a number of aircraft out to interdict and there was some success near the crossroads at Ch’onan. The remnant of the ROK 6th Infantry Division continued to pull back toward the Taejon-Andong Line.

NKA 1st Corps packed up and advanced along the main road through Seoul and on to the village of P’yongt’aek. The large part of 1st Corps’ troops advanced along the same road with the lead elements arriving in the town of Ch’onan. In the central area the 12th Motorcycle Regiment secured the key crossroads at Ch’ungju. The NKA 5th Infantry moved into Chech’on and the 12th Infantry crossed the Han River and attempted to strike the ROK in Tanyang from the flank. The Yak fighter squadron re-based from P’yongyang to Seoul. The Il-2’s performed successful interdiction in the ROK 6th Divisions rear area near Sanju and then returned to the airbase in Seoul. The 12th Infantry ordered an artillery barrage against the ROK infantry in Tanyang, just across the Han River. After much ordnance was expended, the infantry disintegrated, and the attack force met with little resistance.

July 12-14 1950

The 13th Regiment was rebuilt in P’yongyang and was ordered to join the rest of the 6th Division. The 109th Tank battalion fueled and managed to capture Taejon. The 2nd Corps closed in on the remaining ROK troops in the center at Mun’gyong. Again, heavy artillery bombardment wiped out the enemy defenses. The 1st Corps also ordered a heavy barrage against the ROK at Choch’iwon, but somehow, the artillery made no impact. The 6th Infantry went forward with an attack against the ROK 2nd Infantry Division, or rather what was left of it. The ROK had to rely on internal supply as it had been cut off by the NKA tanks. The NKA’s 15th Infantry Regiment was sacrificed but the little hamlet fell to the North Koreans and the ROK 2nd Infantry was destroyed.

The 107th Tank battalion was released and attempted to overrun the ROK’s infantry regiment at Ch’ungju. Again the ROK is forced to use internal supplies. The ROK infantry unit was overcome by the North Korean T-34’s. The 107th battalion pulled back to prevent losses, but the 203rd was released and quickly advanced into the village.

The ROK’s 11th Regiment of the 1st Infantry Division was rebuilt in Pusan. The US 19th and 24th Infantry Regiments landed at Pusan as reinforcements from Japan. The Air Force performed several successful interdiction missions along the Taejon-Taegu road, as well as the road north of Andong. Several units build defensive positions at Taegu, Y’onch’on, and An’gang-ni.

July 15-17 1950

The weather turned sour and prohibited air missions. The US 35th Infantry Regiment sailed to Pusan from Japan as reinforcements. The UN commander continued to arrange for the defense of Pusan. An errant infantry regiment nearly ran to safety from behind enemy lines. Its fate remains to be seen.

The commander of the NKA ordered the 1st Corps to advance. It relocated to Yongdong. The rest of the troops followed suit. The 107th Tank battalion sped through to the coast where it captured a virtually unoccupied Kunsan. The 203rd Tank moved into the village of Muju along with the 109th battalion. The 2nd Corps was ordered forward on the east and it reset to the village of Yongju. 12th Infantry moved through Jangju. 5th Infantry Division captured Andong. There was no enemy contact.

July 19-21 1950

The ROK 12th Infantry Regiment was rebuilt in Pusan for the 1st Division. Two infantry regiments from the US 1st Cavalry Division landed in Pusan as reinforcements. The weather remained inclement and the aircraft were grounded. The wandering ROK infantry regiment was lucky to find their way to the interior lines.

The NKA rebuilt the 15th Infantry Regiment, which was ordered to join the rest of the 6th Division on the front lines to the south. It was moved by rail. The 1st Corps advanced to Kumch’on while the 2nd Corps moved into Andong. No attacks were attempted as the communist forces set up their positions. This stalling allowed the UN forces more time to hasten up their defenses.

July 22-25 1950

The weather cleared and just in time for the NKA to launch an attack against the UN forces. The 105th Tank Division moved on the right flank intending to attack the US 25th Infantry. The NKA 5th Infantry closed in on the ROK in Taegu, and the focused on the point defenses along the river Naktong. The UN commander ordered close air support and soon two squadrons of Mustangs flew in an struck at the 105th Tank. The air support was largely ineffective. A squadron of F-80’s was also called upon to strike at the 105th Tank, but this to failed to produce any results. Lastly, a squadron of F-80’s attacked the main column coming in from the main road and effectively hit the target. The NKA 2nd Infantry Division took heavy casualties. The 1st Corps commander ordered a heavy barrage against the US and ROK troops defending the main road into the Pusan area. Despite the large amount of ordnance spent, the attack made little impact. The GHQ artillery opened up a barrage against the US 24th Regiment on the right flank. This bombardment left the American troops disorganized. The 105th Tank proceeded with its attack despite the failure of the preliminary barrage. The attack went rather poorly for the communist forces and the 203rd Tank Battalion was wrecked. The US 27th Infantry ceded a little bit of ground in order to preserve its strength.

The UN commander took advantage of the clear weather to fly in some additional supplies from Japan. The Navy also flew some of it bombers to perform interdiction against the main railroad. This operation was a complete success. Two squadrons of F-51’s were ordered to go head hunting along the front lines. The proceeded with an air strike against the NKA 16th Infantry. They succeeded in inflicting some damage and left the unit disorganized.


The UN F-51 Mustangs attack the 105th

July 26-28 1950

The ROK 15th and 18th Infantry Regiments were rebuilt. The UN commander called for more close ground support. The FEAF send a couple of squadrons of F-51’s to strike the NKA 3rd Infantry Division, which was in open terrain staging for an attack. The UN aircraft managed to disrupt the enemy. A squadron of Bombers from the Valley Forge took a shot at the 105th Tank, which was also in poor cover, but they were unable to find the target.

The NKA rebuilt the 1st Regiment for the 12th Infantry Division in Pyongyang. The 1st Corps’ engineers constructed an airbase near HQ in order to inhibit the UN from making preemptive air strikes against the attacking forces. A reduced squadron of Yak’s was flown in to provide a patrol zone. The 6th Infantry was ordered to lead an attack against the main defensive position along the Taejon-Taegu road. The UN commander called on the air force to provide close air support. A squadron of F-80’s was ordered to sweep the airbase at 1st Corps, near Kumch’on. The North Korean Yaks were no match for the F-80’s and aborted before incurring any damage. Thus a squadron of F-51’s and a squadron of F-80’s were sent to provide close support without the harassment of enemy fighters. The air barrage was successful and managed to disorganize the NKA’s 6th Infantry Division.

The NKA’s commander called of the attack against the main position and instead focused on the UN’s right flank. The NKA 12th Infantry ordered an artillery barrage against the American 21st Regiment at Y’onch’on. The fire was ineffective due in part to the cover of the village and the hedgehog positions that the Americans had built up. This attack was also deemed to risky and was subsequently called off. A massive artillery barrage was resumed against the point position as artillery reserves were released. The NKA 10th Infantry was also released and advance to stage an assault. This time the Americans felt the artillery and they became disordered. 10th Division then launched a frontal attack. The attack was a partial success, especially considering that it was low odds. The ROK lost a weak infantry regiment, which was defending with the Americans in the defensive positions, but the 10th Infantry Division also took heavy losses. The UN’s position was thus weakened, but remained in UN control.

July 29-31 1950

The US 5th Infantry Regiment and the 89th Tank Battalion were provided to the UN as reinforcements. Both units and supply landed in Pusan from Japan. Cargo planes also took advantage of the clear skies to land more supplies at the airbase in Pusan. The ROK 12th Regiment was ordered to replace the regiment that was destroyed in the hedgehog along the point, which was lost during the previous battle. The 15th Regiment moved from Pusan to garrison the 1st Corps HQ. American Bombers attacked the main railroad line near Osan. This should hamper the NKA’s further efforts to move supplies forward.



The commander of the NKA ordered another preparatory barrage against the front lines around the main road into Taegu. The first attack was rather successful and the US 8th Infantry Regiment was destroyed. A second barrage was directed at the hedge-hogged position on the main road. This time the artillery was ineffective. The NKA’s 3rd Infantry Division was able to effect a crossing of the Naktong River where the US regiment had formerly defended.



August 1-4, 1950

The weather stopped cooperating and the airforces were grounded. Parts of the 1st Marine Division were released as reinforcements along with part of the US 2nd Division and a squadron of Corsairs. The ROK 19th Infantry Regiment was rebuilt in Pusan and reassigned to the 6th Division. American artillery was used to fire at the encroaching 3rd Infantry Division about 10 miles from Taegu. The North Korean troops became disordered, but the UN commander did not continue with a counterattack.

The NKA received two additional infantry divisions as reinforcements along with the 83rd Infantry Regiment. The 5th Regiment was rebuilt in Pyongyang and assigned to the 4th Infantry Division. The 83rd and the 5th regiments moved by rail to join the 1st Corps HQ in Kumch’on. The 7th and 9th Infantry Divisions in Pyongyang used strategic movement to march to the village Kumch’on (N. Korea). The commander of 1st Corps ordered artillery fire against the US troops in the defensive works to the west of Taegu, but the barrage was ineffective and the subsequent attack was called off. 2nd Corps also ordered a barrage against the US troops in Y’onch’on, which was the village on the eastern road to Pusan. This barrage was also ineffective and as a result, the 2nd Corps postponed the attack.

August 5-7 1950

The US 23rd Infantry Regiment and the 2nd Division’s artillery were released for reinforcements and landed at Pusan with supplies. The ROK’s 15th Regiment was rebuilt in Pusan and ordered forward to garrison the 2nd Corps HQ. American artillery fired a barrage at the NKA 1st Infantry Division in order to discourage further attacks. The artillery fire managed to hit the infantry and left them disordered.

The NKA’s commander of the 1st Corps ordered a continuance of artillery fire against the American forces to the east of Taegu, but failed to inflict any significant damage on them. The planned ground attack was postponed. Similarly, the 2nd Corps issued artillery fire against the US troops, which were defending the east road into Pusan. The Americans had built up defensive works but these were not enough to dispel the effects of the barrage. The 5th Infantry Division followed up with an assault against the position. The US 21st Regiment took most of the damage and the 34th Regiment was forced to abandon the hedgehogs. Although the 5th Division had sacrificed the 12th Regiment, other troops advanced across the Naktong and held the bridges.

August 8-11 1950

The 12th Regiment was rebuilt at Pyongyang and moved by rail to the 2nd Corps. It de-trained in Uisong. The 5th Infantry maneuvered into position to attack the beleaguered US troops which had fallen back to the low hills south of Y’onch’on. The 12th Motorcycle drove to the village of Chinbo, where there were key crossroads to the 2nd Corps right flank. The 12th Division relinquished the 1st Regiment to cover 5th Division’s left. The ROK 2nd Corps released the 11th Regiment from reserve and ordered it to reinforce the US 34th which faced an imminent attack. The commander of the NKA’s 2nd Corps ordered the attack despite being informed of the ROK reinforcements. All of his artillery was out of range. The attack failed miserably and the 5th Infantry lost two regiments. The UN commander breathed a sigh of relief, as the road to Pusan remained blocked.

Three tank battalions were readied in Japan for transfer to South Korea along with the 25th Infantry’s transports. The 25th Infantry was upgraded. Three armored battalions and the US 8th Infantry Regiment de-barked at Pusan. The 1st Corps fired the big US guns again at the NKA infantry division, which was positioned to the north west of Taegu. It happened to be the 3rd Infantry and it was successfully put out of action. The North Korean Army’s pressure was beginning to weaken. Or so it seemed.

August 12-14 1950

The weather cleared up enough to allow the airforces to fly. It remains to be seen what effect this will have, but the UN has greatly increased in its air power. The US 25th Division’s artillery regiment and transports arrived in port at Pusan and were unloaded. C-47’s and C-54’s made effective use of the clear weather to bring more supplies into Pusan. The UN commander ordered the Air Force to run interdiction missions against the main railroad from Seoul. A squadron of F-80’s was sent on a preliminary mission to sweep the Yak fighters at 1st Corps’ airbase. The North Korean pilots quickly aborted in the face of the FEAF’s superior force and landed unscathed. Four squadrons of F-51’s and a Squadron of F-80’s were needed to produce successful interdiction results. The UN commander continued to build up for a local counterattack.

The 10th Infantry Regiment was rebuilt at 1st Corps HQ for the 5th Infantry Division. The North Korean commander awaited the arrival of supplies before commencing with a continuation of the attack. More time would be needed to re-supply, but the UN was gaining in strength.

August 15-18 1950

The US 72nd Tank battalion and the 2nd Division’s transports unloaded at Pusan along with supplies. A squadron of F-80’s was ordered to suppress the North Koreans fighter cover near 1st Corps HQ. The Yak fighters aborted before incurring any significant losses. F-51’s were used to interdict the railroad to the north of Taejon. A squadron of Marine F4U’s flew in to barrage the 1st Infantry Regiment, which was caught in the open to the east of Y’onch’on. The North Koreans fled under the heavy air attacks. The Marine Corsairs also attacked the North Korean 7th Infantry Division in the village of Yongch’on. The North Koreans held their position but became disorganized. The ground forces made no attacks as the overall staging continued to progress.

The North Korean commander continued to re-supply with difficulty. First there was the UN’s interdiction, but overall production was lower than expected. A few personnel replacements made their way to P’yongyang.

August 19-21 1950

The clouds rolled back in and severe weather hampered flight and air operations. The North Korean commander ordered both 1st and 2nd Corps to conduct simultaneous attacks against the Pusan Perimeter. The GHQ artillery commenced with a barrage against the US 24th Regiment which was hedge-hogged to the west of the main road. The bombardment was effective and as a result the American unit became disordered. 2nd Corps also fired artillery at the American and ROK troops, which were holding the UN’s right flank to the east of Taegu. These troops also became disrupted.

The North Korean 2nd Corps then threw the 7th and 9th Infantry Divisions into the ROK position, defended by the 11th Regiment and the US 34th Regiment. Both of the UN’s units were wiped out in the attack. The 1st Corps followed through with an all-out attack against the American forces on the western side of Taegu. The 16th Infantry Regiment led the North Korean 3rd and 10th Infantry Divisions into battle. The US 24th Infantry Regiment was overwhelmed but only after bloodying the North Korean 16th Infantry Regiment.

The commander of the 9th Infantry ordered his forces to exploit their success and they moved forward to strike at the ROK 2nd Corps HQ at Kyongju. The 12th Tank was released from reserve to assist. The HQ was garrisoned by the 19th Infantry Regiment and the 1st Sep, battalion. The odds were quite poor for the North Korean attackers but they managed to gain surprise. The 9th Division absorbed a few casualties while the ROK 11th Regiment was destroyed. Nevertheless, the 2nd Corps HQ weathered the attack.

The Commander of 1st Corps sent the 70th Tank battalion over to cut off the North Korean 9th Infantry from the west. The 72nd and 73rd Tank battalions were ordered to advance from Pusan to hit the North Koreans from the south. The UN commander moved artillery to the 2nd Corps for an immediate counterattack. Meanwhile the US 38th Regiment landed in Pusan with supplies. The ROK 2nd Infantry Division advanced into Ulsan. Too bad that the air force is grounded. The UN’s artillery unleashed a heavy barrage against the North Korean 9th Infantry. The artillery fire was costly, but managed to disorder the enemy. The North Koreans found themselves cut off from supply and had to use up internal ordnance and fuel stores. The firefight was intense and the 9th Infantry was destroyed while managing to pull back the 12th Tank battalion. The US 73rd Tank which was the lead unit was wrecked, but tanks were easy to replace. That was an expensive maneuver but hopefully it will discourage the North Koreans from further excursions into the UN’s line of supply.

August 22-25 1950

The North Korean 16th Infantry Regiment was rebuilt at Pyongyang and assigned back to the 4th Division. The 18th Infantry Division arrived as reinforcements and used the railroad to join 1st Corps. 16th Regiment also used rail movement to the village Waegwon. The 12th Tank was pulled back to join the 7th Infantry in Y’onch’on where it replenished its supplies. The North Korean commander decided to continue the assault on the main road near Taegu. First a heavy barrage was ordered and the corps artillery obliged. The American and ROK troops were positioned in hedgehog defenses and weathered the artillery storm, but became disorganized. The North Korean attackers gained surprise and overwhelmed the defensive position. Both the ROK 12 infantry and the US 19th were reduced to nothing. Another step toward the end was taken.

The ROK used replacements to rebuild the 11th Regiment in Pusan. The US also quickly replaced the 73rd Tank battalion. The ROK 2nd Corps opened up with another attack against the North Korean’s left flank along the Naktong. The 5th Infantry Regiment was caught alone in the low hills south of Yongch’on. The American artillery left the unit is disarray. Then the tanks rolled in and eliminated what remained of the 5th Regiment. So far the perimeter is holding.

August 26-28 1950

The weather has continued to be inhospitable for over a week. The FEAF remained grounded. 1st Cavalry Division’s transports landed at Pusan along with supplies. The American commander arranged for another counterattack against the NKA’s left flank. The US artillery was let loose with no regard for conservation. The NKA was left disorganized. The US 38th Infantry Regiment attacked along with the ROK’s Capital Division. As a result, the North Korean 7th Infantry Division absorbed considerable losses and was forced to retreat with the artillery and 12th Tank, back across the Naktong River.

The North Korean commander was forced to build more supply and reorganized his battered lines. The infantry filled in the gaps along the Naktong River and supplies were moved by rail to 2nd Corps. Transports were used to move supplies further. There were no attacks called for as preparations were considered for early September.

August 29-31 1950

The US 24th Infantry Division’s transports landed at Pusan along with the Commonwealth 27th Brigade and additional supplies. The weather continued to hinder flight and thus there were no air operations. The UN commander made a few adjustments in the troop dispositions but made no attempt to break out of the perimeter.

The North Korean 1st Corps received a shipment of supply aboard truck transports and wagons. The commander ordered a barrage against the UN’s defenses in Taegu. The barrage was quite successful and wiped out what was left of the ROK 5th Division. The ROK 3rd was left disorganized and on its own. The 6th Infantry Division led an all-out assault against the city and was supported by the 2nd and 3rd Divisions on either flank. The ROK 3rd Infantry fought courageously but to no avail. Taegu fell to the North for the cost of the 13th Infantry Regiment. For all of that, the perimeter continued to hold.

September 1-4 1950

The skies finally cleared, and there was no doubt that the aircraft would fly. The North Korean army received replacements and rebuilt the 13th Regiment for the 6th Division. The Railroad became quite active and the 13th Regiment traveled to Waegwon and the 27th Division de-trained at Yongdong. The commander of the NKA moved a large force of infantry in to cut away at the UN’s defenses. The UN called in close air support, and soon two squadrons of F-51’s appeared an strafes the 3rd Division. The 3rd Division in Taegu became disorganized. Additionally, two more squadrons were released to strike the 6th Infantry, which was poised to attack from the north side of the Naktong River. The North Korean 2nd Infantry sustained a direct hit and took heavy casualties. The entire formation became disordered. These attacks seemed to do enough damage to stop the North Koreans and give them pause. And the North Korean commandant called off the planned attacks.

The US 1st Marine Division was organized for the purpose of an amphibious assault and the 5th regiment was called to Pusan and sent to Japan in order to join the rest of the division. The 7th Division was also received and would be held back as reinforcements for later use. The 6th Army continued to regulate the troops assigned to hold the Pusan Perimeter. Although no attacks were planned because of limited resources, the FEAF and Marine Air Corps launched a series of strikes against the North Korean infrastructure. A squadron of F-80’s performed a fighter sweep against the meager fighter defense provided by the weak squadron of Yak fighters. Again the North Korean Air Force landed with a whimper and remained grounded. After a number of attacks, finally there was some positive effects from the F-51’s. The main road and rail line endured heavy interdiction. The Marines launched an air strike with their Corsairs against the 3rd Division in Taegu, and these sorties left the North Koreans disordered. The North Korean 1st Infantry was staged in clear terrain and the Marines flew in a squadron of F-4U’s, which strafed the enemy troops. These forces also were suppressed. There was no provision to exploit any of these attacks.

September 5-7 1950

The North Koreans continued to aggressively hold the line against the Pusan Perimeter. The 1st Corps ordered artillery to fire on the US 2nd Division along the perimeter while the 2nd Corps fires at the ROK 6th Division. Both targets were sufficiently suppressed for an attack. In the first attack, the US 23rd Regiment was wiped out in an overwhelming attack, but the NKA lost the 13th Infantry Regiment. Some ground was compromised as the 15th Regiment advanced. The 2nd Corps also launched an assault against the ROK 2nd Regiment to the north of Taegu. The ROK troops disintegrated and the after absorbing a number of losses, the 12th Infantry advanced. Not much ground was gained, but a few weak points became exposed.

UN transport aircraft took full advantage of the clear weather to land supplies in Pusan. It was all rather uneventful. The 1st Marine Division continued to stage for an amphibious landing near Inchon. A squadron of F-80’s was sent to take down the North Korean fighter patrol near 1st Corps HQ. The YAK fighters were easily scared off, but they all landed successfully before incurring losses against the UN’s superior aircraft. F-80 aircraft was successful in its interdiction missions against the main rail line from Seoul.

F-51’s were ordered to barrage the NKA’s 2nd Division, which remained poised to attack the UN perimeter. The fighter-bombers quickly found their target and left the infantry running for cover. The Marine F-4Us were ordered to strafe the 6th Infantry that had recently broken the Pusan Perimeter, but they were unable to find their target. The ROK HQ ordered an artillery barrage against the 6th Infantry. The big guns found the target and managed to inflict disorganization. The UN counterattack commenced and left the NKA wondering whether the breakthrough was worth it. The 15th Infantry Regiment was destroyed. The ROK 17th Regiment plugged the gap and reset the trap.

September 8-11 1950

The weather turned around and prohibited flight. The North Koreans slowly filtered supply from Wonsan to the 1st Corps, but the effects of UN interdiction were being felt. The wearied and disorganized infantry was pulled back from the Pusan Perimeter and fresh units were brought in for a renewed attack. The 1st Corps ordered the GHQ artillery to soften up the US 35th Infantry Regiment with a hail of shells. More NKA artillery fired at the ROK 17th Regiment next door, but this failed to hit the target effectively. Nonetheless, the 1st Corps ordered the two-pronged frontal attack. The Americans were all but wiped out. The NKA’s 3rd Infantry launched an all-out assault against the ROK’s 17th Infantry. The North Koreans took heavy losses against the ROK, which gave a little ground in ordered to save itself. The North Korean commander had to acknowledge that his supplies were starting to become dangerously low.

The UN continued to prepare for an invasion to relieve the perimeter, which was a little, strained. It would be nice to have the weather clear up first. The ROK 2nd Corps began a maneuver against the NKA’s left flank. The 12th Tank battalion was nearly surrounded as a result. The North Korean 2nd Corps returned fire in desperation. The ROK’s 1st Infantry Regiment became disorganized from the battery. The US 25th Division’s artillery was ordered to fire on the 12th Tank battalion with the desired results. Then ROK 2nd Corps gave the order to attack. The Americans were repulsed and the ROK infantry regiment was wrecked. No further attack plans were enacted, as supplies were low.

September 12-14 1950

The clouds quickly drifted out as if by providence. The ROK 12th Infantry Regiment was rebuilt at Pusan for the ROK’s 1st Infantry Division. UN transport aircraft landed at the bases in Pusan with much needed supplies. The 7th Infantry continued to stage for an amphibious landing. The USS Valley Forge and its entourage made its way through the Yellow Sea in order to support the invasion forces. The USS Missouri and the USS Philippine groups appeared outside of Inchon. The landings were all performed to the south of Inchon, which was occupied by an infantry regiment. Reconnaissance indicated a full division in Seoul as well. The landings were rather successful over all.

A squadron of F-80’s went hunting through the patrol zone near 1st Corps, looking to knock down the North Korean Yak’s. Once again the patrol zone was knocked down, as the North Korean pilots thought better of fighting with the superior aircraft. The F-51 Mustangs were sent on a train-busting mission and were successful but sustained attritional losses. The USMC sent a number of F-4U Corsairs on strafing missions all across the Pusan Perimeter. The NKA 3rd Infantry was targeted and hit hard by the fighter-bombers. Likewise the 18th and 27th Infantry divisions were found and left disorganized. On the right flank of the North Korean perimeter, a squadron of Mustangs circled in on the 105th Division. But had no real effect. Mustangs performed some more train busting along the secondary rail line, which was supplying the 2nd Corps.

Aircraft from the USS Valley Forge flew off the decks and ran a barrage mission against the North Korean forces in Inchon. Both F-4u’s and TD’s struck with all of their ordnance. A number of the Corsairs sustained damage during the mission, but it was still judged a resounding success. The North Korean security brigade was demolished, and the 14th Infantry Regiment was left running for cover. The 1st Marine Division assaulted the North Korean troops in Inchon and the 14th Regiment fell apart. Inchon fell to the Americans.



Back in the Perimeter, the 6th Amy launched an attack on the weakened North Koreans. In reality, the NKA 27th Division had become surrounded. But the attack faltered and the ROK infantry took heavy losses. Back at Inchon, the 5th Marine Regiment overran the North Korean airbase at Kimpo and destroyed a significant number of Il-2 aircraft before the pilots could get them airborne. The airbase fell to the marines. The 1st Regiment entered the southern part of Seoul and now the NKA 15th Infantry Division was surrounded. Both rail lines were effectively cut off and the North Koreans had been outflanked.

The North Korean Army rebuilt the 13th Regiment at Pyongyang for the 6th Division. Due to the successful UN interdiction efforts, only a limited amount of fuel supplies made it to the front near Pusan. The main rail line had been shut down by the US 1st Marine Division near Seoul. The North Korean commander ordered both the 1st and 2nd Corps to withdraw to the north. Thus began a massive withdrawal as both corps broke from contact with the UN.

The commander of the 1st Marine Division called in naval air support in order to thwart an anticipated counterattack by the North Koreans in Seoul. The aircraft found the target and the North Korean 15th Infantry Division ran for cover. As a result, any counterattack that may have been planned was moved to the back burner.

September 15-18 1950

The North Korean commander continued to attempt his escape from southern Korea and to stockpile supplies. The 1st Corps provided fuel for a number of motorized units that were making their way to the north and the 2nd Corps like wise was in full retreat. Meanwhile two US tank battalions crossed the Naktong River.

The ROK’s 17th Infantry Regiment was rebuilt in Pusan and assigned to the Capital Division. The US 7th Infantry Division landed approximately 25 miles to the south of Seoul and Inchon, and the 1st Marine Division’s artillery landed with supplies. Meanwhile, the US 1st Cavalry Division traversed the road and recaptured Taejon and continued to advance to the village of Suwon. ROK 1st Corps relocated to the village Hamch’ang to support the US 24th and 25th Divisions in the center. US 2nd Infantry Division advanced to Yongju, covering the 1st Corps right flank. ROK 2nd Corps advanced to Yongdok, along the coastal road.

American aircraft flew in and struck the rear of the retreating columns, and found the 27th Infantry Division. Arriving unscathed by enemy flak, the Corsairs nailed the 27th Division inflicting numerous casualties. UN F-51’s also attempted to strike the forces that were pulling away on the eastern coast. UN F-80’s were assigned interdiction of the road along the North Korean’s central line of retreat.
