Reichswehr personnel

Erich Dethleffsen (2 August 1904 – 4 July 1980) was a German general from Kiel. He was married to the daughter of Nikolaus von Falkenhorst, who planned the German invasion of Norway and Denmark during World War II.

Heinz Harmel (29 June 1906 – 2 September 2000) was a German SS commander during the Nazi era. He commanded the 10th SS Panzer Division Frundsberg during World War II. Harmel was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves and Swords of Nazi Germany.

Friedrich Olbricht (4 October 1888 – 21 July 1944) was a German general during World War II. He is known for being one of the plotters involved in the 20 July Plot, an attempt to assassinate Adolf Hitler in 1944.
Olbricht was a senior staff officer, with the rank of lieutenant general. He was secretly in contact with most of the leaders of the resistance. They briefed him on their various plots and he placed sympathetic officers in key positions. Olbricht quietly encouraged field commanders to support the resistance. By late 1943, his office was the centre of Resistance plotting, under Claus von Stauffenberg. Had the 20 July plot to assassinate Adolf Hitler been successful, Olbricht would have assumed the position of minister of war in a post-Nazi regime.

Rudolf Schmundt (13 August 1896 – 1 October 1944) was a German officer and adjutant to Adolf Hitler. Between 1942 and 1944, he was chief of the German Army Personnel Office. Schmundt was injured during the 20 July 1944 assassination attempt on Hitler and died a few months later from his wounds.
