Adm Nimitz's WWII operational diary posted online

The US Naval War College has released a trove of World War II information by posting online the operational diary kept by the Pacific commander, Adm Chester W Nimitz, during the war against Japan.
The 4,000-page multivolume collection includes a running summary of the situation for every day of the war in the Pacific compiled by Nimitz's planning staff. It is the only known similar document to survive from the war, said Prof John Hattendorf, who teaches maritime history at the Naval War College in Newport, Rhode Island.
The Nimitz "Graybook," named for the gray material in which it is bound, is posted at www.Usnwc.Edu/graybook. Traffic was so heavy yesterday that downloads of the document were inaccessible for several hours. A spokeswoman for the Naval War College said the problem was mostly fixed by yesterday afternoon.

The diary begins on Dec 7, 1941, the day of the attack on Pearl Harbour, with the line: "The war opened with the attack of Japanese aircraft on Oahu." It goes on to list the locations of the Navy's forces throughout the Pacific, the damage sustained that day and what is known about the enemy's position.
Nimitz's planning staff prepared a similar summary for him every day of the war. Unlike other commanders during World War II, Nimitz kept them, and the diary was found in his personal papers, Hattendorf said. It also includes supporting documentation for the summaries, including the orders Nimitz received from Washington and elsewhere, intelligence information from other commanders and exactly what his fleet units were doing.

The entries run through Aug 31, 1945, as the war in the Pacific came to an end.

The diary was declassified in 1972 and is kept at the Naval History and Heritage Command in Washington, making it accessible only to those who can travel there. Hattendorf said the project to digitise it, make the text searchable and put it online will make it easier for scholars worldwide to study the diary and what Nimitz knew as he made command decisions.
"We'll really be able to understand in a much better way how Adm. Nimitz thought and the challenges he saw every day of the war," he said. "It can be searched for particular information, when particular information was known by the commander, how we reacted to a particular change ... What the president was telling him."

Nimitz, who died in 1966, graduated from the War College and lectured there several times. The project was funded through the Naval War College Foundation.
