Battle of the Naktong Bulge was a major engagement in August 1950 during the Battle of Pusan Perimeter in the early months of the Korean War. United States and Republic of Korea forces defended a salient along the Naktong River against repeated assaults by the Korean People's Army as part of a larger effort to break the perimeter and capture Pusan. The fighting involved river crossings, armored counterattacks, and intense infantry combat that helped blunt the People's Volunteer Army-style offensive before United Nations forces could stabilize the southern defensive line.

Background

The Korean War began in June 1950 when the Korean People's Army invaded South Korea, rapidly advancing toward Seoul and Pusan. By August, the United Nations Command had established the Pusan Perimeter to hold the southeast tip of the peninsula, with the Naktong River forming a key defensive barrier. Commanders such as Douglas MacArthur and Walton Walker coordinated units including the United States Eighth Army, 2nd Infantry Division (United States), and 24th Infantry Division (United States) to resist Choe Yong-gon's plans for a decisive penetration. Prior battles at Taegu and Taebaek Mountains influenced force dispositions and strained logistics around the Pusan Perimeter.

Prelude

Intelligence indicated that elements of the Korean People's Army planned a concentrated crossing of the Naktong River to exploit a bulge in UN lines near Yongsan and Haman. United States commanders, including John H. Church of the 2nd Infantry Division (United States), prepared local defenses using armor from the 24th Infantry Division (United States) and artillery assets from Eighth Army Artillery Command. Reinforcements from the Republic of Korea Army were moved to threatened sectors while naval gunfire support from United States Navy cruisers and destroyers stood offshore to interdict crossings. Supply difficulties and gaps created by earlier withdrawals after the fall of Seoul complicated preparations.

Battle

KPA forces initiated heavy attacks with river crossings under cover of darkness, attempting to infiltrate across the Naktong River near Taegu and along the bulge between Haman and Yongsan. Assaults by divisions of the Korean People's Army were met by concentrated fire from United States Army artillery units, counterattacks by United States Marine Corps-adjacent elements, and armored thrusts from M24 Chaffee and heavier tank units. Close-quarters fighting took place in riparian terrain, rice paddies, and small villages; combat involved combined-arms coordination among Eighth Army (United States), United States Air Force close air support, and Navy gunfire. Commanders such as Walton Walker ordered local withdrawals and counteroffensives to straighten the line, while logistics officers worked to ferry ammunition and medical supplies across precarious routes. The KPA exploited shortages and intermittently achieved bridgeheads, but repeated UN counterattacks, including envelopment attempts by the 2nd Infantry Division (United States), contained the penetrations. Notable actions included night river fights, artillery-directed raids, and use of demolition to deny bridge sites.

Aftermath

The fighting fixed substantial KPA forces east of the Naktong River and depleted their capacity for coordinated offensive operations against the Pusan Perimeter. Although the Korean People's Army inflicted local losses and temporarily threatened routes to Pusan, UN defensive measures and counterattacks arrested the bulge and prevented a breakthrough. The engagement set conditions for subsequent UN operations, including the Inchon Landing planning led by Douglas MacArthur, by stabilizing southern defenses. Command assessments blamed KPA overextension and logistical shortfalls while praising rapid US divisional responses. The battle influenced later force rotations involving the 24th Infantry Division (United States), 25th Infantry Division (United States), and ROK brigades.

Order of Battle

United Nations Command - United States Eighth Army headquarters elements - 2nd Infantry Division (United States) - 24th Infantry Division (United States) - Attached artillery and engineer units from Eighth Army Artillery Command - Naval fire support elements from United States Seventh Fleet - Air support from United States Air Force tactical squadrons - Republic of Korea Army infantry brigades and militia units

Korean People's Army - Multiple KPA divisions committed from the North Korean People's Army order of battle - River-crossing and assault battalions supported by limited armored elements - Logistics and engineering detachments for pontoon and ferry operations

Casualties and Losses

Both sides suffered significant casualties and materiel losses during the engagements around the bulge. United Nations forces sustained killed, wounded, and missing among infantry, armor crews, and artillery units, while numerous vehicles, small arms, and some tanks were damaged or destroyed. The Korean People's Army incurred heavy infantry losses, depletion of assault units, and the loss of bridging equipment and supplies in failed crossings. Exact figures vary among postwar assessments compiled by United States Army Center of Military History, Republic of Korea Ministry of National Defense, and contemporaneous United Nations Command reports; estimates place losses in the thousands for KPA and several hundred for UN forces during the period of the battle.
