Tactics of Mistake Free Audiobook

Gordon R. Dickson (Author)
I first read this book years ago. Recently, I bought an used copy for a trip. It is still a classic!
THe plot is unusual-Grahme is a scholar/tactician assigned to a force fighting a guerilla war on one of the dozen colony worlds. Earth is divided into the Alliance/Coalition camps who fight their wars through these colonies. Grahme has some very unique ideas about fighting wars and, through deception and ruse, puts into into action and wins the war. Grahme’s foil is Dow Castries, an Earth politician bent on world(s) domination. Grahme believes the new worlds should be free of Earth and chooses the Dorsai as his weapon. Grahme designs a novel training/strategy/tactics regime for the Dorsai to transform themselves into the best mercenaries in the universe. Using his Dorsai, Grahme wins several important successes that prompt Dow to unite the Earth into an all-out war. Grahme defeats Dow and paves the way for the new world’s freedom.
The most interesting part of the story is not the military action-like most military amateurs Dickson is fighting the last war (Vietnam)- but Grahme’s grasp and control of historical forces and his ability to manipulate people into his scheme, without their knowing it. It’s a masterful attempt at persuasion and manipulation which sets in motion the novel’s sequels.
