"Halsey eventually received the five-star rank. The Congress, in an effort to compensate Spruance and to acknowledge his wartime achievements, authorized full pay for life as a four-star admiral, whereas all other naval officers received reduced pay upon retirement. A controversy has continued ever since, the gist being that Halsey's publicity had own his fifth star, and that Spruance had been at a disadvantage because he had avoided publicity. Many efforts were subsequently made to promote Spruance to Fleet Admiral, all reportedly thwarted by Vinson. After Vinson retired, still more attempts were made, but the Navy has been unwilling to reopen the case. The Navy's reasoning is that Spruance was the only World War II naval officer who retired on full pay by a special act of Congress, and thereby he had been appropriately recognized and honored by the people of America. Spruance expressed his personal feelings on the matter in a 1965 letter to Professor E.B. Potter of the United States Naval Academy. "So far as getting my five star rank is concerned," wrote Spruance, "if I could have had it along with Bill Halsey, that would have been fine; but, if I had received it instead of Bill Halsey, I would have been very unhappy over it. The present situation is that World War II will have been over twenty years next August, which is a long time. Also, the central and western parts of the Pacific Ocean are a long way from Washington.""
