What if Halsey had allowed the American battle line to face the Japanese fleet off Samar?
Short answerThe United States probably wins, but the Japanese resistance makes it a costly battle rather than an easy sweep.
NotesThe American force would probably prevail because of its strength, but the Japanese ships would not be passive targets. Their battle line retained dangerous guns, experienced crews, and the ability to fight back. A direct surface engagement would therefore impose American losses. The counterfactual works best as a costly US victory rather than an effortless sweep at Leyte Gulf.
