Read it years ago in a book about the oddities of WW2. I'd like to know the full story.

You'll never know the full story. There are so many versions as to what really happened in 1941, ranging from Suvorov's theory that Hitler's attack was an act of desperation and that Stalin had a plan to attack on 6th July 1941 (he wrote three rather convincing books that support this thesis), to Gorodetski's theory which views Stalin as a total idiot who ignored all signs on heaven and hearth (which is by the way also convincing when you read his books). You simply have to do a research and create your own conspiracy theory.:-)
