Did the bolsheviks prove any significant threat to the british goverment in the russian civil war?

This might sound a little bit odd but i dont know the exact question its a long story…. Anway the word Britishi dont know if this the exact word i this case i know its starts with a B maybe it is correct but whoever is doing this essay. If they think that it might be a different kind of threat then the british please let me know.
