The Battle of Osan (

US Army
forces in South Korea.

A North Korean tank column equipped with ex-Soviet T-34/85 tanks overran the task force in the first encounter and continued its advance south. After the North Korean tank column had breached US lines, the task force opened fire on a force of some 5,000 North Korean infantry that were approaching its position, which held up their advance. North Korean troops eventually flanked and overwhelmed the US positions, and the rest of the task force retreated in disorder.

Outbreak of war

Main articles:
Initial phase of the Korean War

During the night of June 25, 1950, ten divisions of the

South Korean Army suffered from widespread lack of organization and equipment and was unprepared for war.[2] The numerically-superior North Korean forces destroyed isolated resistance from the 38,000 South Korean soldiers on the front before they began moving steadily to the south.[3] Most South Korean forces retreated in the face of the invasion. The North Koreans had captured South Korea's capital, Seoul, by June 28, which forced the government and its shattered army to retreat further south.[4]

To prevent South Korea's collapse, the

Eighth United States Army, headquartered in Japan. Military spending cuts meant that the division was understrength and using outdated equipment.[7]

Division Commander

C-54 Skymaster transport aircraft airlifted one battalion from the division garrison under Smith's command into Korea. The battalion deployed quickly to block advancing North Korean forces and performed a holding action while the rest of the division could be moved to South Korea by sea.[8]

Task Force Smith

When you get to

Pusan, head for Taejon. We want to stop the North Koreans as far from Pusan as we can. Block the main road as far north as possible. Make contact with General Church. If you can't find him, go to Taejon and beyond if you can. Sorry I can't give you more information—that's all I've got. Good luck, and God bless you and your men!

The first units of the 24th Infantry Division left

high explosive anti-tank (HEAT) rounds were issued to the battery, all of which were allocated to the number six howitzer sited forward of the main battery emplacement.[11] A Battery also had four .50 calibre M2 Browning heavy machine guns and four bazookas.[14]

Most of the soldiers of the task force were teenagers with no combat experience and only eight weeks

C-rations.[17]

By July 1,

Taejon.[12][19] The task force soon after began moving north by rail and truck to oppose the North Korean Army.[20] Task Force Smith was the first of several small US units sent into Korea with the mission to take the initial "shock" of North Korean advances[21] and to delay much larger North Korean units with the goal, which would buy time to allow more U.S. units into Korea. Task Force Smith's mission was to move as far north as possible and to begin engaging the North Koreans to stem their advance so that the rest of the 24th Infantry Division could be moved into South Korea to reinforce it.[12][22] The 24th Division commander, William F. Dean, personally ordered Smith to stop the North Korean force along the highway from Suwon and "as far from Pusan" as possible.[9][23]

Three days later, on July 4,[18] it dug in on two hills straddling the road north of the village of Osan, 6 miles (9.7 km) south of Suwon and about 25 miles (40 km) south of Seoul.[9][24] The ridges rose to 300 ft (91 m) above the road, which provided visibility almost the entire distance to Suwon. The battalion set up a 1 mi (1.6 km) line over the ridges.[17] There, they waited to meet the advancing North Korean forces.[7] The force was placed along the road with the infantry formations on the two hills, five of the howitzers 1 mi (1.6 km) behind the infantry, and the sixth with its six HEAT shells positioned halfway between the infantry and the other five field artillery pieces.[25] Heavy rain made air support impossible and so Smith and Perry preregistered the artillery battery in the hope it would be just as effective.[13] The heavy machine guns and bazookas of A Battery along with a volunteer crew were sent forward to reinforce the infantry.[14]

Battle

Tank columns

At around 0730 on July 5,

107th Tank Regiment, North Korean 105th Armored Division heading south toward them.[26] The North Korean forces, driving south from Seoul, pursued retreating South Korean forces.[27] At 08:16, the artillery battery fired its first rounds at the advancing North Korean tanks.[7] The tanks, which were around 2 km (1.2 mi) from the infantry force, were hit with numerous 105 mm howitzer rounds, but they were unaffected.[1] When the tanks closed to 700 m (2,300 ft), the 75 mm recoilless rifles fired and scored direct hits on the lead tanks but did not damage them.[11] The North Korean tanks returned fire but could not locate the American positions and gun emplacements, and their fire was ineffective.[1][11]

Once the tanks reached the infantry line

Second Lieutenant Ollie Connor fired 22 2.36-inch rockets at a range of 15 yd (14 m) from his M9A1 launcher tube. Only some of these ignited, but several struck the rear plate armor of several T-34s, where their armor was thinnest. The warheads failed to penetrate the armor, however, and the North Korean tanks continued their advance, ignored the roadblock, and continued down the road. The operators assumed that the roadblock was manned by South Korean troops and ignored it since it did not pose them a serious threat.[28] When the tank column came over the crest of the road, the forward howitzer, commanded by Corporal Herman V. Critchfield, the chief of section, and crewed by five cannoneers, fired its HEAT rounds, damaged the first two tanks, and set one of them on fire.[1] One of the crew members of the burning tank emerged with a PPSh-41 and killed a member of an American machine gun crew before he was killed himself; the American became the first casualty of Korean War ground combat. He was later identified, incorrectly, as Kenneth R. Shadrick.[29] The howitzer, depleted of HEAT rounds, began firing high explosive rounds before it was destroyed by the third T-34. The tanks then advanced and continued to ignore the American howitzer and bazooka fire. The US forces managed to disable another North Korean T-34 when a 105 mm shell struck and damaged its tracks.[30] The tracks of the T-34 tanks cut the communication signal wires between the infantry and artillery forces, which further compounded the confusion. Perry was wounded in the leg by North Korean small arms fire as he attempted to get the crew of the disabled tank to surrender. His artillery force continued firing at the North Korean tanks without effect.[29]

The second column of 25 T-34 tanks approached the task force within an hour. The new T-34 formation advanced singly or by twos and threes close together with no apparent formal organization. The howitzer battery hit another tank from the column in its tracks, disabled it, and damaged three more. The North Korean tanks had destroyed the forward howitzer (number six) and wounded one of its crew members, killed or wounded an estimated 20 infantrymen, and destroyed all of the parked vehicles behind the infantry line. At the main battery position, one of the five remaining 105 mm guns had been slightly damaged by a near-hit.[1][31] Several of the men in the artillery battery began deserting their positions, but Perry managed to convince most of them to return.[32] Although Smith later stated that he believed that the rounds had deteriorated with age, the ineffectiveness of the 2.36-inch bazooka had been demonstrated repeatedly during World War II against German armor.[33] Because of peacetime defense cutbacks, the 24th Infantry Division had never received improved M20 3.5-inch bazookas with M28A2 HEAT antitank ammunition, which could defeat Soviet tanks.[34] After the last tanks had passed their lines, no North Korean forces were spotted for around an hour.[32]

Three more tanks were sighted advancing from the north at around 11:00.

Lee Kwon Mu, which were advancing from Seoul.[32] The column apparently was not in communication with the tanks that had preceded it, and the North Korean infantry was not aware of the Americans' presence.[31]

At 11:45, when the column had advanced to within 1,000 yd (910 m) of the Americans, Smith gave the order for the task force to open fire with everything that it had.[1] The mortar, machine gun, artillery, and rifle fire destroyed several trucks, which scattered the column. The three lead tanks moved to within 300 m (980 ft) of Task Force Smith and opened fire. Behind them, around 1,000 of the infantry formed in the rice paddies to the east of the road in an attempt to flank the American forces, but they were repulsed. Smith attempted to order artillery fire on the North Korean force, but runners were unable to get back to the field artillery positions and so he assumed they had been destroyed by the tanks.[35] Within 45 minutes, another enveloping force formed to the west of the road, which forced Smith to withdraw a platoon to the east side of the road. The US infantry then began to take mortar and artillery fire from the North Koreans.[1][36]

American withdrawal

Task Force Smith managed to hold its lines for three hours, but at 14:30, Smith ordered the Americans to withdraw since they suffered from low ammunition and a breakdown of communications.

John Toland that the American forces at the battle seemed "too frightened to fight."[6]

The retreat quickly broke down into a confused and disorganized

Pyongtaek and Cheonan, picking up stragglers along the way and eventually joined units of the 24th Infantry Division that had established a second line of defense.[39]

Task Force Smith's force had 250 return to the American lines before nightfall, with about 150 more of the force killed, wounded, or missing. Most of the other stragglers found their way into the American lines over the next several days. The last stragglers from 2nd Platoon, B Company, reached Chonan five days later, only 30 minutes ahead of the North Korean Army. Upon the initial count, Task Force Smith suffered 20 killed in action, 130 wounded in action or missing in action, and around 36 captured.[39] After the end of the war, the figures were revised to 60 dead, 21 wounded and 82 captured, 32 of whom died in captivity. That casualty count accounted for 40% of Task Force Smith.[1] The US troops advancing northward during the Pusan breakout offensive would later discover a series of shallow graves containing the bodies of several soldiers of the 24th Infantry Division. All of them had been shot in the back of the head, with their hands bound behind their backs with communications wire.[41] North Korean casualties were approximately 42 dead and 85 wounded, with four tanks destroyed or immobilized. The North Korean advance was delayed approximately seven hours.[37][42]

Aftermath

The Battle of Osan was the first US ground action of the war.[43] The fight showed that American forces were weak and unprepared for the war, and outdated equipment was insufficient to fight North Korean armor and poorly trained and inexperienced units were no match for better-trained North Korean troops,[1] but the disparity in number of troops engaged certainly had a profound effect on the outcome of that battle and others. Undisciplined US troops abandoned their positions prematurely and left equipment and wounded for North Korean troops to capture.[37] Smith also said he felt he had stayed too long in his position, which allowed North Korean troops to envelop the force and cause heavy casualties as it retreated.[1] Those weaknesses would play out with other US units for the next month as North Korean troops pushed them further back.[44]

Though the force was badly defeated, Task Force Smith accomplished its mission of delaying North Korean forces from advancing for several hours.

Pusan, where the Battle of the Pusan Perimeter would culminate in the eventual defeat of the North Korean Army.[47]

Three months later, on September 19, Osan would be the location where the US and UN forces, under the command of the Eighth Army, advancing from the south, would meet up with forces of

Inchon Landings, as both forces were in an offensive pushing the North Koreans back, which would culminate in a complete defeat of the North Korean Army in the south.[48]

In the years after the Korean War, the US Army used the areas in Japan that Task Force Smith had trained as a memorial. A monument to Task Force Smith was also established on the Osan battlefield,[49] where an annual commemoration of the Battle of Osan is held by the Eighth Army, which is still headquartered in South Korea.[50] On July 16, 2010, sixty years after the Battle of Osan, Eighth Army leaders, in conjunction with government officials of Osan, held another ceremony, speaking of Task Force Smith and describing the engagement as "the opening shots of a war of ideas that exists even today."[51] On the 61st anniversary, another ceremony was held by both the US military and Osan politicians to remember the task force.[52]

Memorial

There is a memorial park - 'Osan Jukmiryeong Peace Park' in Osan. This park has museum and monument and opened in July 2020.[53]
