In August 1930, when Berlin SA leader Walter Stennes had his men attack the Berlin Party headquarters, it was Daluege's SS men who defended it and put the attack down. Sometime afterwards in an open letter to Daluege, Adolf Hitler proclaimed "SS Mann, deine Ehre heißt Treue!" ("SS man, your honour is loyalty"); and "Meine Ehre heißt Treue" (My honour is loyalty) was duly adopted by the SS as its motto.[13] Hitler promoted both Daluege and Heinrich Himmler to SS-Obergruppenführer, with Daluege the SS leader of northern Germany while Himmler controlled the southern SS units out of Munich in addition to serving as national leader for the entire SS.
