The Battle Analysis Series is a compilation of all information, drawn from both Allied and Japanese sources, available to the Naval War College at the time of publication (1953-1958) and is, as stated in the preface, an "endeavor to maintain at all times the viewpoints of the commanders of the units involved on both sides." Its major strength is in the painstaking detail with which battle actions are reconstructed. Roll 1 includes a variety of battles, including those at the Coral Sea, Midway, the Savo Islands, and Surigao Strait. The Battle of Leyte Gulf is covered in great detail on rolls 2 and 3.
