<P> After the war, 148 Koreans were convicted of Class B and C Japanese war crimes, 23 of whom were sentenced to death (compared to 920 Japanese who were sentenced to death), including Korean prison guards who were particularly notorious for their brutality during the war . The figure is relatively high considering that ethnic Koreans made up a very small percentage of the Japanese military . Justice Bert Röling, who represented the Netherlands at the International Military Tribunal for the Far East, noted that "many of the commanders and guards in POW camps were Koreans--the Japanese apparently did not trust them as soldiers--and it is said that they were sometimes far more cruel than the Japanese ." In his memoirs, Colonel Eugene C. Jacobs wrote that during the Bataan Death March, "the Korean guards were the most abusive . The Japs didn't trust them in battle, so used them as service troops; the Koreans were anxious to get blood on their bayonets; and then they thought they were veterans ." </P> <P> Korean guards were sent to the remote jungles of Burma, where Lt. Col. William A. (Bill) Henderson wrote from his own experience that some of the guards overlooking the construction of the Burma Railway "were moronic and at times almost bestial in their treatment of prisoners . This applied particularly to Korean private soldiers, conscripted only for guard and sentry duties in many parts of the Japanese empire . Regrettably, they were appointed as guards for the prisoners throughout the camps of Burma and Siam ." The highest - ranking Korean to be prosecuted after the war was Lieutenant General Hong Sa - ik, who was in command of all the Japanese prisoner - of - war camps in the Philippines . </P> <P> Following the dropping of atomic bombs on Hiroshima and Nagasaki, and the impending overrun of the Korean peninsula by Russian forces, Japan surrendered to the Allied forces on 15 August 1945, ending 35 years of Japanese occupation . </P> <P> American forces under General John R. Hodge arrived at the southern part of the Korean Peninsula on 8 September 1945, while the Soviet Army and some Korean Communists had stationed themselves in the northern part of the Korean Peninsula . U.S. Colonel Dean Rusk proposed to Chischakov, the Soviet military administrator of northern Korea, that Korea should be split at the 38th parallel . This proposal was made at an emergency meeting to determine postwar spheres of influence, which led to the division of Korea . </P>
