In the early 1920s, a tiny group was formed within the SA to serve as Hitler's personal bodyguard. Originally labelled the "Stosstruppe Adolf Hitler", they later became known as the SS - Schutz Staffeln, or "protection squad". This second of four titles covers the first wave of expansion: the Sixth Division "Nord"; the Austrian Seventh Mountain Division "Prinz Eugen" which fought Tito's partisans; the housed cavalry of Eight Division "Florian Geyer" which operated on the Eastern Front; and the two formidable new Panzer Divisions, Ninth "Hohenstaufen" and Tenth "Frundsberg", which fought the Western Allies in 1944.
