The Germans lost World War One but the German Air Force, to this day, has a fighter squadron named in honor of the Red Baron, Manfred von Richthofen, Jagdgeschwader 71 "Richthofen".
Hell, we in America even named a pizza after him.
But why go so far away from home to find examples? Fort Benning, Fort Bragg and Fort Hood are all named in honor of Confederate warriors.
So was the USS Stonewall Jackson (SSBN-634)
Losing a war does not dimish the respect that is due an honorable warrior.
