SS-Hauptsturmführer Fritz Klingenberg at the time he gained fame as the man who captured Belgrade. With a small group of Das Reich men he took the city, simply by raising a swastika over the German Embassy and declaring the capital captured. Two hours later the mayor of Belgrade surrendered to Klingenberg, not knowing that sizeable German forces were miles away from the city and Klingenberg was virtually alone! The Yugoslav army stacked its arms in the city square, and Klingenberg had all of the men register. The handful of Germans had just captured more than 1,300 troops and a city with a population of over 200,000 without firing a single shot. For this audacious action Klingenberg was awaded the Knight’s Cross.
