Can't work out to quote but @ Ford Prefect,in a perfect world we can all think that Uboat commanders were humanitarian in their conduct,unfortunately the harsh reality of WW2 was that many of them did share the ideologies of the Nazi Regime

To the last point correct me if I am wrong if the Japanese lie to their kids about WW2 & the west sought to atone for their "sins" as such,why is there a blank space in German history?
Yes war is atrocious in all forms but to leave out the historical significance of what happened in that specific timeframe?!?
