For his contributions during the war, he received military honors including both classes of the Iron Cross, the Royal House Order of Hohenzollern with Swords, and other decorations.

Interwar period and World War II
After World War I, Hagen transitioned to the Reichswehr. He held various positions, including serving in the Abteilung Fremde Heere and later as the commander of the Truppenübungsplatz Neuhammer. In 1935, he joined the Wehrmacht and continued his military career.
