主题：1919-1924年波兰抓获的苏联战俘 -- 一直在混

The Russian historians arrived at this number by first estimating the number of POWs, then subtracting the number that has been repatriated to the Soviet Union after the hostilities ended, and then assuming that most of the remainder died in POW camps[3]. Polish historians always countered this by arguing that: (a) the number of POWs was very difficult to estimate accurately, due to the chaotic situation prevailing for most of the war, and (b) many Soviet POWs lost that status after they switched sides and entered units fighting alongside Polish forces against the Red Army, or were transferred to the Whites rather than the Bolsheviks[3]. There was also the problem that significant number of Russian POWs were left in the territory of Poland since World War I (about 3.9 million soldiers of the Russian Empire were taken captive by the Central Powers) and obviously when the Polish-Soviet conflict deteriorated, these POWs were not released to Russia.[3][4]

2004年两位波兰的历史学家和一个莫斯科州立大学的教授合作得出来的这个数字，老实说，我觉得上面那些理由加起来的话，这个数字并不怎么准确。
