USS Harder (Ss-257): The Destroyer Killer of the Pacific War (Paperback) (ISBN-13: 9798180594129)

In the summer of 1944, a fleet submarine operating in the waters off the Philippine coast sank her fifth Japanese destroyer and did not return. She had been hunting destroyers since her fourth war patrol, turning toward the charging escort rather than away from it, firing the down-the-throat shot that the prewar doctrine had never imagined as an offensive first choice, and coming back each time with the patrol report that confirmed the kill. The USS Harder did not come back from the seventh patrol. What she left behind was a record that changed how the Pacific submarine force understood the most dangerous moment in submarine warfare - the moment the escort turned toward the submarine and accelerated to flank speed.

USS Harder (SS-257): The Destroyer Killer of the Pacific War is the definitive analytical account of Sam Dealey's command and the tactical doctrine whose development transformed a defensive emergency into a systematic offensive method. At its center is the problem Dealey spent six patrols solving: how to turn the charging destroyer's prosecution run - the threat the prewar doctrine had specified as the occasion for depth, silence, and patient endurance - into the firing geometry of a confirmed kill. The down-the-throat shot was not Dealey's invention. It was his doctrine: the deliberate, prepared, reproducible application of a fire control solution whose geometry the charging escort was producing by its own behavioral predictability, executed across four confirmed destroyer kills before the seventh patrol's silence closed the account.

This book follows the Harder's seven war patrols with the analytical density and the narrative honesty that the full operational record demands. It examines Dealey's combat philosophy in the tactical detail that the patrol reports document, traces the progressive development of the anti-escort method from the preparatory observations of the first three deployments through the Ikazuchi's sinking and the fifth patrol's two-day consecutive destroyer sequence, and places the Harder's destroyer attrition within the strategic context of the Philippine Sea campaign whose operational conditions the accumulated escort losses had been shaping since the fourth patrol's first confirmed kill. It reconstructs the Medal of Honor action's operational complexity - the surface rescue conducted in waters the Harder's own prior success had made acutely dangerous - without the commemorative compression that the citation's language imposes on the full weight of what the situation required. And it follows the Harder into the waters off Dasol Bay with the knowledge that the method whose prior applications had always worked was about to encounter the conditions under which it would not.

Drawing on war patrol reports, Japanese anti-submarine records, ULTRA intelligence documentation, Medal of Honor proceedings, and the serious scholarly literature on the Pacific submarine campaign, this book reconstructs the Harder's operational history with the precision the documentary evidence supports and the analytical honesty that the full record - the destroyer kills, the rescue actions, and the final silence off western Luzon - requires.

Sam Dealey turned toward the charging destroyer. He did it five times. The Pacific submarine force learned from every one of them.
