On 4 December 1950, Hudner was part of a six-aircraft flight supporting U.S. Marine Corps ground troops who were trapped by Chinese forces.
At 13:38, he took off from Leyte with squadron executive officer Lieutenant Commander Dick Cevoli, Lieutenant George Hudson, Lieutenant Junior Grade Bill Koenig, Ensign Ralph E. McQueen, and the first African American Naval Aviator,  Ensign Jesse L. Brown, who was Hudner's wingman.
The flight traveled 100 miles (160 km) from Task Force 77's location to the Chosin Reservoir, flying 35 to 40 minutes through very harsh wintery weather to the vicinity of the villages Yudam-ni and Hagaru-ri.
The flight began searching for targets along the west side of the reservoir, lowering their altitude to 700 feet (210 m) in the process.
The three-hour search and destroy mission was also an attempt to probe Chinese troop strength in the area.

Though the flight spotted no Chinese, at 14:40 Koenig radioed to Brown that he appeared to be trailing fuel.
The damage had likely come by small arms fire from Chinese infantry, who were known to hide in the snow and ambush passing aircraft by firing in unison.
At least one bullet had ruptured a fuel line.
Brown, losing fuel pressure and increasingly unable to control the aircraft, dropped his external fuel tanks and rockets and attempted to land the craft in a snow-covered clearing on the side of a mountain.
Brown crashed into a bowl-shaped valley at approximately 40°36′N 127°06′E, near Somong-ni, 15 miles (24 km) behind Chinese lines, and in 15-degree weather.
The aircraft broke up violently upon impact and was destroyed.
In the crash, Brown's leg was pinned beneath the fuselage of the Corsair, and he stripped off his helmet and gloves in an attempt to free himself, before waving to the other pilots, who were circling close overhead.
Hudner and the other airborne pilots thought Brown had died in the crash, and they immediately began a mayday radio to any heavy transport aircraft in the area as they canvassed the mountain for any sign of nearby Chinese ground forces.
They received a signal that a rescue helicopter would come as soon as possible, but Brown's aircraft was smoking and a fire had started near its internal fuel tanks.

Hudner attempted in vain to rescue Brown via radio instruction, before intentionally crash-landing his aircraft, running to Brown's side and attempting to wrestle him free from the wreck.
With Brown's condition worsening by the minute, Hudner attempted to drown the aircraft fire in snow and pull Brown from the aircraft, all in vain.
Brown began slipping in and out of consciousness, but in spite of being in great pain, did not complain to Hudner.
A rescue helicopter arrived around 15:00, and Hudner and its pilot, Lieutenant Charles Ward, were unable to put out the engine fire with a fire extinguisher.
They tried in vain to free Brown with an axe for 45 minutes.
They briefly considered, at Brown's request, amputating his trapped leg.
Brown lost consciousness for the last time shortly thereafter.
His last known words, which he told Hudner, were "tell Daisy I love her."
The helicopter, which was unable to operate in the darkness, was forced to leave at nightfall with Hudner, leaving Brown behind.
Brown is believed to have died shortly thereafter of his injuries and exposure to the extreme cold.
No Chinese forces threatened the site, likely because of the heavy air presence of the VF-32 pilots.

Hudner begged superiors to allow him to return to the wreck to help extract Brown, but he was not allowed, as other officers feared an ambush of the vulnerable helicopters resulting in additional casualties.
In order to prevent the body and the aircraft from falling into Chinese or North Korean hands, the U.S. Navy bombed the crash site with napalm two days later; the aircrew recited the Lord's Prayer over the radio as they watched flames consume Brown's body.
The pilots observed that his body looked to have been disturbed and his clothes stolen, but he was still stuck in the aircraft.
The remains of both Brown and the aircraft were never recovered.
