The Secretary of State to the Ambassador in the Soviet Union (Harriman)
813. The Polish Ambassador a few days ago informed the Dept that a group of underground leaders who had entered into negotiations with the Soviet military authorities in Poland had disappeared. We are also informed that similar information including names originating with Polish authorities at London had been cabled on April 2 to Clark-Kerr by the ForOf with instructions to query the Soviet ForOf. Press reports datelined London79 now state that these leaders are engaging at Moscow in negotiations with the Russians for the reorganization of the so-called Lublin Government. Confidential and allegedly non-Polish sources here make similar allegations which are received with a certain reserve.
Dept leaves to your judgment whether it would serve a useful purpose to make a similar inquiry of the ForOf.
