Well Sokrates here's something new you can learn today about one such Soviet 'liason officer' from someone who met him face-to-face during the Rising:
Fighting Warsaw by Stefan Korboński last Chief of the Polish Wartime Undergound
page 386.
"...An early sensation was the arrival of a
Captain of the Soviet Intelligence Service, Constanty Kalugin, who reported to the High Command of the Rising. On August 5th he sent a telegram via London to Stalin asking for help. I also read his appeal to German units formed of Soviet soldiers who had been taken prisoner-of-war; urging them not to take part in the fighting against the Rising on pain of death. The telegram Kalugin sent to Stalin received no reply."
Andrzej Ulankiewicz a former solider of AK battalion 'Parasol' defending the Cherniakow bridgehead now living in USA mentions fighting alongside a soldier of Berling's Polish Army (WP) in his unpublished memoir 'Parasol'. You could contact him via the Warsaw Rising museum if you would like him to confirm this directly to you.
That AK battalion 'Parasol' was linking up with Berling's Polish Army is mentioned in passing on warsawuprising.com/witness.htm
Korboński also records Berling sending two battalions of Polish 1st Corps across the Vistula to the Cherniakow bridgehead only for most of them to be cut down by German machine gun fire.
Fighting Warsaw-page 388.
I know that some random flights by Polish volunteers from RAF were done as well as a token few flights by RAF but these were if anything purely symbolic in proportion.
You have obvioulsy not read any of the records so you just mouth another dumb statement.
