Neptune's Inferno_ The U.S. Navy at Guadalcanal - James D. Hornfischer [232]
WHILE HEPBURN WAS CONVALESCING in Hawaii, American intelligence analysts were starting to divine from movements of troops, aircraft, and ships that the Japanese might be shifting to the strategic defensive. But something in the radio traffic suggested otherwise. Stymied by a change in Japanese ciphers, they took what they could from the radio traffic. Again and again they heard references to something known as “Operation KE,” evidently planned to take place somewhere in New Guinea or the Solomons.
Nimitz believed Yamamoto might still have plans to strike at and reinforce Guadalcanal. When Halsey’s intelligence staff saw signs in the third week of January that at least three carriers, the Zuikaku, Zuiho, and Junyo, were at Truk, along with the super battleships Yamato and Musashi, there was good reason for vigilance. Confronted with the possibility of another major naval assault, Halsey resolved to finish the replacement of the war-weary Marine units on Guadalcanal while things were still relatively quiet. He ordered transports to bring in the last of the Army’s 25th Division and take off the marines. A powerful element of the South Pacific Area naval force was ordered to support them and cover the withdrawal.
In desperation, the Imperial General Headquarters had drawn up an even more ambitious plan. As forces gathered at the great naval base in the Carolines, Japan’s service branches were regrouping to defend the central and northern Solomons—and preparing to throw their fullest effort into Operation KE. After five months of attrition, Halsey and his staff were blameless in thinking it was another reinforcement effort.
Emperor Hirohito was sensitive about the public’s opinion of a campaign that had emerged as a showcase of the Japanese will to fight. In public he held to the view that an opportunity for victory lay for the taking in the Solomons. In an Imperial Rescript broadcast to the nation on December 26, the very same day that the Imperial General Headquarters decided to withdraw, the emperor declared that “dawn is about to break in the Eastern Sky” and announced that forces then gathering would head toward the Solomons for the decisive battle.
In a meeting with his high commanders a few days later, however, the Emperor decided to do what until then was unthinkable. The Imperial Army would not reinforce. It would withdraw. Compelling testimony of the morbid state of Japanese soldiers on the island came from diaries taken from the dead. In late December, when deaths by starvation were tolling at a rate of more than a hundred a day, a Japanese
