„We needed to face the task to be able to provide the missing weapons latest at the start of an armed conflict. Similar to the US Army, which during peace times was little more powerful than our Reichswehr, had planned for a case of emergency based on the experience during the world war I in 1917. My journey to the US as Commander in Chief of the Armed Forces in 1927 provided very good insights for our needs.” This is how General Wilhelm Heye described his visit to the US and started a chapter of relations of the Reichswehr to a foreign force which has not been paid much attention to date. While the secret connections of the Reichswehr to the Red Army have been met with broad scientific interest and were subject of widespread investigation, the collaboration with the U.S. Army has so far not been in the focus of historical research. The missions between 1922 and 1933 of almost 30 officers, including well-known names such as Wilhelm Speidel, Werner von Blomberg and Walter Warlimont, are therefore almost completely unknown. | A Master Thesis by Paul Fröhlich (in German).
