Following the
outbreak of war between
North Korea and South Korea on June 25, 1950, the United States mobilized a large contingent of troops to send into the beleaguered country. Initially, units occupying Japan were sent, but forces were eventually dispatched from the United States. The
North Korean People's Army, meanwhile, was preparing for a
September offensive by capturing the
Miryang and
Samnangjin areas to cut off the 2nd Division's route of supply and withdrawal between
Daegu and Busan. They had only established their lines shortly before the North Koreans began their attack. The North Koreans began crossing the Naktong River under cover of darkness at certain points. On the southernmost flank of the
US 9th Infantry Regiment river line, just above the junction of the Nam River with the Naktong, A Company of the 1st Battalion was dug in on a long finger ridge paralleling the Naktong that terminates in Hill 94 at the
Kihang ferry site. A small village called
Agok lay at the base of Hill 94 and from the river.

Naktong River during the
Second Battle of Naktong Bulge in September 1950. That evening, Kouma led the patrol of two
M26 Pershing tanks and two
M19 Gun Motor Carriages in Agok, along the Naktong River. By 22:15, this strike intensified and North Korean mortar preparation struck A Company's positions. American mortars and artillery began responding with
counter-battery fire. He was wounded shortly thereafter in the foot reloading the tank's ammunition. He quickly fought off another North Korean attack across the river with his machine gun. At one point, the tank was surrounded and Kouma had to engage the North Koreans from outside the tank with machine gun fire at point blank range. After the
tank gun's ammunition was expended, Kouma used his pistol and
grenades to hold off the North Koreans. The tank then withdrew to the newly established American lines, destroying three North Korean machine gun positions along the way. During his action, Kouma had killed an estimated 250 North Korean troops. and who had been the second most decorated US soldier in the war. His single-handed heroic battle may have served as a seed for the fictional WWII movie,
Fury (2014 film). Once he returned to his unit, Kouma attempted to resupply his tank and return to the front lines. Instead, the wounded Kouma was ordered to evacuate for medical treatment. As he was being evacuated, Kouma again requested to return to the front lines. ==Subsequent career and retirement==
