Tactics of Mistake, by Gordon R. Dickson, paperback science fiction novel
“The first in the award-winning Dorsai Cycle
Planets were the pawns in their quest for power…
The men of the Dorsai were the finest fighting soldiers in the universe, mercenary troops without equal.
Their talents were devastatingly employed on Kultis, where a bloody little war raged between the Western Alliance and the Eastern Coalition. But not even the Dorsai could anticipate the dramatic effect of Cletus Grahame’s brilliant mind and the galaxy-shaking theory he called ‘The Tactics of Mistake’.
The story of how Cletus Grahame risked his life, the fate of three worlds, and ultimately the whole of the Dorsai to prove that a mistake may remake worlds is a classic of science fiction.”
