Help finding records on...........?

My great-great grandfather. Some of you may have heard of him, Maxim Czerniak, the Russian anarchist. I looked up my great-grandfather and found his obituary with Maxim's name in it, which was what I was trying to find. When I looked up Maxim on google I found 3 good sources, but my computer told me they didn't exist. :\ So, if anyone has information on him, I'd appreciate it. Really all I know is that he'd created his own army and got beaten, with only about 4 or 5 men surviving. Thanks.
