Did the Red Army or Vlasov’s army liberate Prague from the Nazi?

In this article you will find more or less truthful description of early May 1945 days in Prague. I strongly recommend to read it and to post comments:
"Today there is a chance that the events of early May, 1945 would be cleaned of political bargaining. But it would happen not in the nearest future, large debates between two states historians have been heating for many years. However, there are less people both in Russia and the Czech Republic who question the decisive role of the Red Army in Prague liberation. Finally, May 1945 should be differed from the Socialist epoch in Czechoslovakia. They should not be mixed. These events are not equal even if somebody wants it so much."
