This chapter summarizes the points of the book, highlighting the areas where the cavalry proved valuable, as well as those times when the cavalry failed. It also provides a short discussion on the relationship between combat, security, and reconnaissance, and how they are inextricably linked. It also argues that the army needs a balance of different kinds of forces to succeed, and that cavalry is an absolutely critical member of that team. It agrees that the doctrine of the cavalry was inadequate, but that that mattered less than has often been argued.
