From The Anguish of Surrender: Japanese POWs of World War II, by Ulrich Straus (U. Washington Press, 2005), p. 191:
The last Japanese POW challenge to Allied prison authorities took place in the spring of 1945 at the British-run facility at Bikaner, located on the edge of the Indian desert some two hundred forty miles west of Delhi. In this camp, originally constructed to house German prisoners of the First World War, the first prisoner was Senior Sergeant Aoki Akira, whose plane was shot down over Rangoon and crash-landed. He eventually became one of the POW section leaders. Although a Japanese citizen, as were all Koreans at the time, Aoki was a member of the royal house of Korea. Mizui Hajime, a Japanese fellow prisoner deeply imbued with the justice of Japan’s cause, paid Aoki the ultimate tribute of noting that he possessed “a high degree of military spirit as well as strong leadership qualities,” even though he spoke Japanese with a heavy accent.
In a curious historical footnote, Aoki, reverting to his family name Rhee, achieved a measure of renown in 1949 when he became the first commandant of the Republic of Korea’s nascent air force academy. In the following year, shortly after the outbreak of the Korean War, it was Colonel Rhee who took possession of a shipment of ten American P-51 Mustang fighters at Itazuke Airfield on Kyushu. After only three days of training on the new planes, Colonel Rhee, still full of the old fighting spirit, led a formation of three P-51s in a low-altitude raid on a North Korean concentration of T-34 tanks south of Seoul. Hit in the exchange of fire, Rhee crashed his plane into the enemy formation on a suicidal dive and was posthumously promoted to the rank of brigadier general.
