I looked for the Pearl Harbor attack investigations in the hope of finding an answer to that telegram question and found only HUGE file size PDF SCANS (painfully sluggish in PDF viewer) not keyword searchable -
"Collected here are documents from the 23 volume, 40 part, 25,000 page report of HEARINGS BEFORE THE JOINT COMMITTEE ON THE INVESTIGATION OF THE PEARL HARBOR ATTACK CONGRESS OF THE UNITED STATES SEVENTY-NINTH CONGRESS which was released on July 20, 1946."
I found this is interesting tidbit. "You are extremely competent! You're fired! Oh, you were right... shhhhhhhhhh."
Admiral James O. Richardson

James Otto Richardson (18 September 1878 – 2 May 1974) was an admiral in the United States Navy who served from 1902 to 1947. As Commander in Chief, United States Fleet (CinCUS), he protested against the redeployment of the Pacific portion of the fleet forward to Pearl Harbor, believing that a forward defense was neither practical nor useful, and that the Pacific Fleet would be the logical first target in the event of war with Japan, vulnerable to air and torpedo attacks. He was subsequently relieved of command in February 1941. His concerns were to be proved justified in December.
Beginning in January 1940, he was Commander in Chief, United States Fleet (CinCUS), which was command of both the Scouting Force (Atlantic Fleet) and Battle Force (Pacific Fleet). At the time of his appointment, Richardson was particularly suited for the post.
"[Richardson] was one of the Navy's foremost figures. Since his earliest days, after leaving Annapolis, he had made the study of Japanese warfare his life's work. He was beyond question the Navy's outstanding authority on Pacific naval warfare and Japanese strategy.[1]"
He held this position during a stressful period marked by
Presidential orders to deploy the Pacific part of the Fleet to Pearl Harbor from its traditional naval base in San Diego, California. Richardson noted that:
"... In 1940, the policy-making branch of the Government in foreign affairs – the President and the Secretary of State – thought that stationing the Fleet in Hawaii would restrain the Japanese. They did not ask their senior military advisors whether it would accomplish such an end.[2]"
Richardson protested this redeployment to President Franklin D. Roosevelt and to others in Washington. He did believe that advanced bases like Guam and Hawaii were necessary but that insufficient funding and efforts had been made to prepare them for use in wartime. He also believed future battles in the Pacific would involve aircraft carriers and more scouting forces would be needed to locate them. Richardson recognized how vulnerable the Fleet was in such an exposed and remote position, a logistical nightmare only made worse by the slim resources, and lack of preparation and organization.[3] Richardson argued such a forward defense was not practical or useful, despite Japan's attack on China and whatever promises had been made to Britain to come to their aid if attacked. According to journalist John T. Flynn:[1] The Fleet had little in the way of housing, materials, or defensive mechanisms at Pearl Harbor. Richardson wanted to return to the West Coast, prepare the Fleet, and then perhaps return to Pearl Harbor.
"It was Richardson's belief – and indeed generally supported by the Navy – that the Fleet should never be berthed inside Pearl Harbor where it would be a mark for attack. This was particularly true in such troubled times when the airways of the East were hot with rumors of approaching conflict. What is more, Richardson held the belief that Pearl Harbor was the logical first point of attack for the Japanese High Command, wedded as it was to the theory of undeclared and surprise warfare. For ten years the U.S. Navy held "attacks" on the Army defenses at Pearl Harbor, and were always successful. Defending the base was rather hopeless, in his mind.[1]"
Richardson made two trips to Washington to meet with Roosevelt to discuss the issue. He followed this up with an official letter to the Chief of Naval Operations (CNO), Admiral Harold R. Stark, pointing out that it was Richardson's firm conviction that neither the Navy nor the country was prepared for war with Japan:
"I believe my official letter of October 22, 1940, in regard to the dismal state of the Navy's War Plans, was probably one factor which made Stark accept with equanimity the President's urge to have me relieved.[2]"
