If you did not catch, 1st Polish Army was fighting in the east under the Red Army command. It's rather difficult to count them as pro-London Government biased source."Read his memoirs, you read accounts from the 1st Army and the official history, now read the front commanders memoirs".
Moreover why in your opinion Rokossowski is more valuable source than soldiers who actually fought on the Vistula river, without artillery and air support. Is that because it supports your point of view?
Nice, you call all cities close to the frontline to start uprising. And when at last one of them responds you start complaining... then why are you calling at all?"Soviet radio called on all cities to start uprisings"
