Scholarly studies on the Battle of Midway are prolific, yet few have examined the pivotal role American and Japanese submarines played. Fewer still have challenged the prevailing wisdom held among historians that US airstrikes on vulnerable Japanese fleet carriers marked a turning point in the war, essentially prohibiting Japan from further major naval operations. Midway Submerged presents detailed arguments regarding the tactics employed in the US strategy for the Battle of Midway and effectively argues that submarine warfare played a greater role in the battle's outcome than previously thought. Through meticulous research, military historian Mark W. Allen examines the tactics, performance records, American and Japanese naval doctrine, and each participating submarine's actions. He concludes that the Japanese defeat should not be blamed on ineffective submarine tactics; instead, Allen advocates a closer inspection of the overall Japanese strategic plan. Furthermore, he creates a compelling and engaging new argument that Admiral Chester W. Nimitz made an appropriate decision to use submarines defensively. Allen shows that Nimitz correctly used his available assets to defend Midway against a Japanese amphibious assault, reigniting a need for more scholarly debate on this subject. For scholars of military history, this is a worthy and much-needed addition to the body of work on the Battle of Midway.
