Gen. Władysław Sikorski: Mr. President, I have to state in your presence that your declaration concerning the amnesty is not being implemented. Many of our most valuable men still remain in labour camps and prisons.
Stalin (making a note): It is not possible because the amnesty applied to all and all
the Poles have been released.
Gen. Władysław Sikorski: I have here with me a list of about four thousand officers who were taken away by force and who are still kept in prisons and labour camps. These persons are here. None of them has returned.
Stalin: It is not possible. They have fled.
Gen. Władysław Anders: Where could they have fled to?
Stalin: Well, to Manchuria.
