Concerning the Great Helmsman (barf), he was like many Chinese kids who knew or read The Three Kingdoms. It the classic Chinese story of three warring kingdoms, their generals, their strategy and how they fought one another. The other classic that we all read today is Sun Tzu's The Art of War. Mao also read that.
One of the best military leaders in American history who was completely unschooled is Nathan Bedford Forrest. He had a fifth grade education and rose to become one of the best cavalrymen in the Confederacy. Of course, his reputation is tarnished for having been the head of the KKK.
Even before Forrest, a self-taught (he read a lot of books) officer who lost every battle but won the campaign was Nathaniel Greene. He was sent to take over the Department of the Carolinas after Benjamin Lincoln surrendered one army at Charleston and his successor, Horatio Gates outran his defeated army at Guilford Court House. Greene was sent down with little resources and had to rebuild the Southern Army. He did, but lost every battle. Despite this, he managed to recapture North & South Carolina for the Colonies. Huzzah! Huzzah! Huzzah! Washington choose wisely.
