The Quiet Admiral, A Biography of Admiral Raymond A. Spruance, Thomas B. Buell. This is widely considered to be the best biography of Spruance, currently available in this reissued edition. Buell nicely contrasts Spruance with Halsey, his co-commander of the combined third and fifth fleets from 1944, as well as looking at his handling of Midway, the battle that made his name.
