We Cannot Escape History by John T. Whitaker, Published in 1943

This 1943 book goes into detail for the first 300 pages or so about the nature of war, who will lead Britain after Winston Churchill, Nazi Germany, and France's future. Seeing as this is a book published so close to Pearl Harbor itself, there isn't as much content as one might like but this gives an insightful, while also brief, account of Pearl Harbor as the war is still in action.

For the last 40 pages or so, Whitaker deciphers Japan's motives and explains how the U.S. planes were much like "sitting ducks" at Pearl Harbor.

Pearl Harbor: The Story of the Secret War by George Morgenstern, Published in 1947

This book provides facts and many interpretations to the American public over a period of four and one-half years. The facts come from many sources and in a slightly disjointed form but ultimately gives valuable primary accounts of Pearl Harbor directly following the war.

In addition to what you have been given there are two other areas I would look.

1. Is the hearings and reports from the various service and Congressional Boards. Congress's report was begun just after the surrender of Japan and its report published in late 1945, it is available free online as well since it is an official report.

2. The other would be Samuel Elliott Morrison. Commissioned as an officer and eventually Rear Admiral during the war, his specific purpose was to help document the Navy at war. And after the war his multi volume work became the semi official history of the USN in WW2. Now it is far from perfect, full of his personal opinions half truths and lacking many still at the time classified or unexamined facts, but it is still a landmark work as it were. And worth the time for the wealth of info he does provide and the depth of access he was given in essentially experiencing the war for the express purpose of writing the navy's history in it.
