I'm reading The Weimar Republic and Nazi Germany by Warren B. Marris, Jr. (Nelson-Hall, Chicago), 1982 for an eassay. It outlines the power that the Sturmabteilung (abbreviated S.A., trans Stormtroopers, also known as The Brown Shirts) had in 1934: It had its own "private air force, medical service, engineers corps, and intelligence service." (pg 201)
What happened to these divisions after Hitler had the leaders murdered on June 30th, 1934, "The Night of the Long Knives"? Were they taken over by the military, the S.S. or kept by the weakened S.A.? It seems unlikely that such valuable forces would be disbanded while Hitler was re-arming Germany, but given the greatly decreased importance of the S.A. it also seems unlikely they remained under S.A. command.
If answers could include citations I would greatly appreciate it. Thank you.
