Battle of Chosin Reservoir Upon returning to the United States, McCool decided to stay in the Marine Corps. By the start of the
Korean War in 1950, McCool was promoted to
chief warrant officer and was assigned to the 1st Service Battalion,
1st Marine Division as a supply officer. During the
battle of Chosin Reservoir, McCool was attached to Task Force Drysdale, a composite force of
British Royal Marines, US Marines,
US Army soldiers, and South Korean troops. On November 29, 1950, the ill-fated task force fought its way through Chinese forces from Koto-ri to Hagaru-ri. Although the front of the convoy reached Hagaru-ri, the center was badly
ambushed and cut off. Fighting in subzero temperatures throughout the night,
Major John N. McLaughlin assumed command, and Chief Warrant Officer McCool and several other officers helped McLaughlin organize the remaining elements of the center of the convoy. After approximately 40 men had been killed and with very little
ammunition remaining, McCool and 80 other survivors, half of whom were wounded, surrendered as prisoners of war in the early morning hours. Also captured in that same convoy was
Staff Sergeant Charles L. Harrison, who had also previously been held as a POW during World War II.
Second experience as POW McCool and the other prisoners marched north for several weeks, usually at night and during blizzards in order to avoid detection from
UN aircraft. Many of the prisoners suffered from
frostbite and
malnourishment, and they were also randomly interrogated at times during their journey. On December 26, McCool and other officers arrived at
Kanggye, near the Chinese border. Several of the POWs died during the march and shortly after arriving in Kanggye. The Chinese put McCool and the other POWs through a rigorous
communist indoctrination program for eight weeks. In March, Warrant Officer McCool, Major McLaughlin, and several other Marine officers were moved to Camp 5, on a peninsula on the
Yalu River in
Pyoktong. The conditions in Camp 5 were brutal, and many prisoners died from starvation and lack of medical care. McCool was one of the last prisoners to receive the
Sacrament of Penance from
Captain Emil J. Kapaun. Kapaun, an
Army Chaplain, died shortly after and was posthumously awarded the
Medal of Honor. In November 1951, McCool and the other officers were transferred 10 miles east to Camp 2 in Pi-chong-ni, where he would remain for the rest of the war. At one point during his captivity, McCool spit out a window and accidentally hit a guard. He was punished by being sentenced to
solitary confinement in a hole three feet square by three and a half feet deep. Feces covered the floor of the hole, along with an abundant number of
lice and
fleas, and spikes were put through the lid covering the hole, forcing McCool to sit in a hunched position. After 50 hours in confinement, McCool was taken to the camp headquarters where the Chinese demanded he confess to rape and pillaging. Refusing, he was sent back to the hole. McCool was offered words of encouragement from fellow prisoners 70 hours into his ordeal. McCool considered suicide, however, he ended up confessing that he cursed the North Koreans and hated the Chinese Communists. He refused to incriminate his fellow officers in crimes. After 80 hours, McCool was finally released from confinement and returned to the camp. Fellow prisoners gave McCool clean clothing and helped him wash himself. McCool was
repatriated on September 5, 1953 during
Operation Big Switch, after nearly three more years of captivity. McCool later reflected on both of his POW experiences, stating that he hated the Chinese much more than he hated the Japanese. He believed that while the Japanese were just as brutal as the Chinese, the Japanese had character and the Chinese had none. == Later career and life ==
