In stead of reading the summaries some here give - good, but still nothing but summaries - why don't you read Garbe? It's all there. Thick as a brick, but a truly great history of JWs and WWII. The pre-Hitler persecution, early Hitler acts, Rutherford's attempts at coming to terms, Balzereit, conventions, campaigns, internal strife within the camps, factions among the JWs - it's all there. So summaries here are nothing "new", nothing that is "hidden from the JWs", "shocking news" or anything like that. Read Garbe - or a couple of the other good German historians for that matter. Good books. And nothing neither a JW or an ex-JW should be afraid of. Just plain good old-fashioned research with all the pro's and con's, all the successes and setbacks.
