HOW OP-20-G GOT RID OF JOE ROCHEFORT

Parker, Frederick D.·2000·Cryptologia

Abstract

In late October 1942, LtCmdr Joseph Rocherfort, USN, was dismissed from his job as officer in charge of the Navy's radio intelligence center in Honolulu. Trained in both Japanese language and radio intelligence, he had been sent there a little over a year before by OP-20-G, the element in naval communications in overall charge of radio intelligence. During that time he had seen his beloved Pacific Fleet in both defeat and victory. His contributions in radio intelligence in that short time were legendary among his colleagues in Hawaii and his services were so highly valued by the Commander in Chief of the Pacific Fleet, Admiral Chester Nimitz, that, after the American victory at Midway, he was recommended for a Distinguished Service Medal. This article describes how and why, so early in the war, this multi-talented naval officer lost his job in Hawaii and spent virtually the entire war outside the intelligence field altogether.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
