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.
