My point was that he was giving a bit of a break-relatively speaking-that was denied to the less senior officers, because of his rank and popularity among the German public.
I don't really know how the others were killed exactly, though I'm sure that their fate was just as unpleasant.
I found this online:
"It is etimated that 4,980 Germans were executed after the July Plot. Hitler decided that the leaders should have a slow death. They were hung with piano wire from meat-hooks. Their executions were filmed and later shown to senior members of both the NSDAP and the armed forces."
And this:
"In subsequent days, Hitler's police rounded up the remaining conspirators, many of whom were tortured by the Gestapo to reveal their confederates and hauled before the Volksgericht (People's Court) to be excoriated by the dreaded Nazi judge Roland Freisler. About 180 to 200 plotters were shot or hanged or, in some cases, viciously strangled with piano wire or hung up on great meat hooks. "
