Sorge did not predict June 20th either. The closest he got was June 15. He sent a message on June 20th that said 'war is inevitable' or something to that effect. The following is a list of sources I used for my paper, not counting at least two books in Russian:

Read Whymant's book "Stalin's Spy" if you want the messages he sent translated. Read Murphy to see the contradictory information coming into the GRU and NKVD from abroad. Use your common sense, and if that fails logic, to understand Stalin's and Golikov's situation, amongst others, when viewing the reports coming in.
