TIMELINE OF TERROR UNDER THE NATIONAL SOCIALIST GERMAN WORKERS' PARTY

p. 8 “Outward signs of Hitler's debt to the Freikorps movement were the swastika, the brown shirt and the Hitler salute, all of which had been previously adopted by Freikorps units.”  The SS: Alibi of a Nation, 1922-1945 (Paperback) by Gerald Reitlinger

p. 331 “General Kortzfleisch had the right idea. He called for an ancient Teutonic ritual, a shout of 'Sieg Heil' before the blood-spattered bodies. Yet, even now, mystery attended the doings in the ugly, grey ßendlerstrasse building.”  The SS: Alibi of a Nation, 1922-1945 (Paperback) by Gerald Reitlinger

1934 “The first fruits of the army's consent to the blood-purge, the obligation to send contingents to the Nuremberg party rally of September 1934 and the introduction of the Nazi form of greeting (though not yet the Nazi salute), were very bitter to the old officer corps. But Himmler took particular pleasure in any occasion which advanced the assimilation of army and party. p. 79 of  The SS: Alibi of a Nation, 1922-1945 (Paperback) by Gerald Reitlinger

1934 “Keitel renounced the armed forces' rights of military trial on 4 August. Ten days earlier he had agreed at Goering's instigation to impose the Nazi salute throughout the armed forces. This step had been delayed exactly ten years from Hindenburg's death on 2 August 1934." p. 343 of The SS: Alibi of a Nation, 1922-1945 (Paperback) by Gerald Reitlinger
