Battle of Chonan

Outbreak of war On the night of June 25, 1950, 10 divisions of the North Korean People's Army launched a full-scale invasion of the nation's neighbor to the south, the Republic of Korea. The force of 89,000 men moved in six columns, catching the Republic of Korea Army completely by surprise, resulting in a disastrous rout for the South Koreans, who were disorganized, ill-equipped, and unprepared for war. Numerically superior, North Korean forces destroyed isolated resistance from the 38,000 South Korean soldiers on the front, advancing steadily south. Most of South Korea's forces retreated in the face of the invasion, and by June 28, the North Koreans had captured Seoul, South Korea's capital, forcing the government and its shattered forces to withdraw south. The United Nations Security Council voted to assist the collapsing country. United States President Harry S. Truman subsequently ordered ground troops into the nation. However, U.S. forces in the Far East had been steadily decreasing since the end of World War II five years earlier. At the time, the closest forces were the 24th Infantry Division of the Eighth United States Army, which was performing occupation duty in Kyushu, Japan, under the command of Major General William F. Dean. However, the division was under strength and was only two-thirds the size of its regular wartime size. Most of the 24th Infantry Division's equipment was antiquated due to reductions in military spending following World War II. Despite these deficiencies, the 24th Infantry Division was ordered into South Korea, Early engagements From the 24th Infantry Division, one battalion was assigned to be airlifted into Korea via C-54 Skymaster transport aircraft and move quickly to block advancing North Korean forces, while the remainder of the division was transported to South Korea on ships. The 21st Infantry Regiment was determined to be the most combat-ready of the 24th Infantry Division's three regiments. The 21st Infantry's 1st Battalion was selected because its commander, Lieutenant Colonel Charles B. Smith, was the most experienced, having commanded a battalion at the Battle of Guadalcanal during World War II. On July 5, Task Force Smith engaged North Korean forces at the Battle of Osan, delaying over 5,000 North Korean infantry for seven hours before being routed and forced back. During that time, the 34th Infantry Regiment set up a line between Pyongtaek and Ansong, south of Osan, to fight the next delaying action against the advancing North Korean forces. The 34th Infantry Regiment was similarly unprepared for a fight; in the ensuing action, most of the regiment withdrew to Chonan without engaging the enemy. The 1st Battalion, left alone against the North Koreans, resisted their advance in the brief and disastrous Battle of Pyongtaek. The 34th Infantry could not stop North Korean armor because the equipment had not arrived that could penetrate the thick armor of the T-34 tank. After a 30-minute fight, the battalion mounted a disorganized retreat, with many soldiers abandoning their equipment and running away without resisting the North Korean forces. The U.S. forces at Pyongtaek and Ansong were unable to delay the North Korean force significantly or inflict significant casualties on the enemy. == Battle ==

Opening moves Having pushed back U.S. forces at both Osan and Pyongtaek, the North Korean 4th Infantry Division, supported by elements of the North Korean 105th Armored Division, continued their advance down the Osan–Chonan road, up to 12,000 men strong under division commander Lee Kwon Mu in two infantry regiments supported by dozens of tanks. They were well-trained, well-equipped, and had high morale following previous victories, giving them advantages over the poorly trained and inexperienced Americans. Following the retreat from Pyongtaek, the scattered 1st Battalion, 34th Infantry, retreated to Chonan, where the rest of the 34th Infantry Regiment was located. Also in the town were elements of the 1st Battalion and 21st Infantry that had not made up Task Force Smith at the Battle of Osan. Brigadier General George B. Barth, 24th Infantry Division's temporary artillery commander, ordered the 1st Battalion, 21st Infantry to hold positions south of town before Barth left for Taejon. The 1st Battalion, 34th Infantry, was sent to join it. At the same time, L Company of the 3rd Battalion, 34th Infantry, was ordered to probe north of the city and meet the advancing elements of the North Korean 4th Infantry Division. Major General Dean, commander of the 24th Infantry Division, telegraphed the command from Taejon, ordering the rest of the 3rd Battalion, 34th Infantry to move up behind L Company. Regimental commander Colonel Jay B. Lovless moved north to join L Company, along with newly arrived Colonel Robert R. Martin, a friend of Dean's. By this time, most South Korean troops and civilians had abandoned the region, leaving only the U.S. forces to oppose the North Korean Army. Martin and Lovless returned to the 34th Infantry's command post, as the 3rd Battalion, 34th Infantry began setting up defensive positions several miles north of Chonan under the command of 34th Infantry Operations Officer John J. Dunn. It was two hours before the main North Korean force advanced through this position. The battalion returned to Chonan in disorder. By 1700, it re-established defensive positions around the town's northern and western edges, around a railroad station. The 1st Battalion, still disorganized and under-equipped after its engagement at Pyongtaek the day before, remained in defensive positions south of the town. It would not see combat in Chonan. Around 1800, Dean ordered Martin to take command of the 34th Infantry Regiment from Lovless. The 3rd Battalion managed to destroy two of the tanks with rockets and grenades, but the column cut off two companies of the 3rd Battalion from the rest of the force. As the 3rd Battalion, 34th Infantry, began to pull back to rally points, the 1st Battalion began to come under mortar fire from North Korean forces but withdrew without engaging them. As this was happening, General Dean arrived south of the town with Lieutenant General Walton Walker to observe the conflict, and the final elements of the 34th leave Chonan. Dean ordered the 34th Infantry Regiment to retreat to the Kum River. 3rd Battalion, 34th Infantry, now down to 175 men, had lost two-thirds of its strength in Chonan, around 350 men. Most of the battalion's heavy equipment, including mortars and machine guns, was also lost. The North Korean radio reported that 60 Americans were taken prisoner in the town. The regiment began its retreat in the late afternoon, with North Korean forces moving on ridges parallel to the regiment. Most of the battalion moved out on foot and by truck, resting on the evening of July 8 before arriving at the Kum River on July 9 and setting up new defensive positions. ==Aftermath==

The 34th Infantry pulled back to the Kum River, its two battalions being mauled in the battles of Pyongtaek and Chonan. It delayed North Korean forces for 14–20 hours, allowing the 21st Infantry Regiment to set up the next delaying action at Chonui and Chochiwon. The 34th Infantry subsequently set up defensive fortifications along the Kum River, resting for several days until it was engaged in the Battle of Taejon, and was principally in charge of the defense of the city, as the weakened 21st Infantry and 19th Infantry were less prepared for the fight. The battle at Taejon resulted in the near destruction of the 24th Infantry Division. Although the force was badly defeated militarily, the 24th Infantry Division accomplished its mission of delaying North Korean forces from advancing until July 20. American forces had set up a defensive perimeter known as the Pusan Perimeter, along the Naktong River and Taegu to the southeast. This perimeter saw the next phase of the battle and the ultimate defeat of the North Korean army in the Battle of Pusan Perimeter. During the battle, Robert R. Martin, the 34th Infantry Regiment's commanding officer, was posthumously awarded the Distinguished Service Cross for his actions at Chonan, the first decoration awarded during the Korean War. == References ==
