Additionally, Blumentritt acted as a kind of ambassador between the SS and the Army in France after the coup attempt. Over 1,000 SS officers—including the head of the SS in France, Carl Oberg, and the head of the SS Security Service in Paris, Helmut Knochen—had been arrested by the German military commander in France, Carl-Heinrich von Stülpnagel, who was complicit in the plot. This presented a problem for the Army when it was revealed that Hitler was still alive and in charge. After a meeting in Paris, Blumentritt was able to work out a deal with Oberg and Knochen whereby relations were patched up between the Army and the SS, and the involvement of many of the conspirators in Paris was never discovered.
