About point 10, what is the source of this info?

From sources on history.com, the information is quite opposite to this: 600 Italian cavalrymen, with sabers drawn, attacked about 2000 soviets armed with machine guns, and manage a small victory at the battle of the Don:

With sabers drawn, about 600 Italian cavalrymen yelled out their traditional battle cry of “Savoia!” and galloped headlong toward 2,000 Soviet foot soldiers armed with machine guns and mortars. On August 23, 1942 (some sources say August 24), the cavalrymen—part of the Axis invasion of the Soviet Union during World War II— were attempting to close a gap that had opened up between the Italian and German armies along the Don River. It was to be the end of an era. Though experts believe that smaller and less well-documented cavalry charges likely occurred later on in World War II and possibly as late as the 1970s in Rhodesia (now Zimbabwe), they generally describe this as the last major charge in history.
