 Leeb participated in battles around Lorraine, Northern France, Galicia, the Carpathian Mountains, Flanders and the German withdrawal from Northern France.Leeb's older brother, Wilhelm Ritter von Leeb, had the knightly rank of "Ritter" and the nobiliary particle of "von", not by birth, but thanks to the conferment of the Bavarian Military Order of Max Joseph and a patent of nobility.Hence, the older brother had “von” between his names, but the younger brother did not.
