The Civil War is most remembered for the grand battles that have come to define it: Gettysburg, Antietam, Shiloh, among others. However, as bestselling author Patrick K. O’Donnell reveals in The Unvanquished, a vital shadow war raged amid and away from the major battlefields that was in many ways equally consequential to the conflict’s outcome.

War can settle disputes, topple tyrants, and bend the trajectory of civilization—sometimes to the breaking point. From Troy to Hiroshima, moments when war has ended in utter annihilation have reverberated through the centuries, signaling the end of political systems, cultures, and epochs. Though much has changed over the millennia, human nature remains the same. In The End of Everything, military historian Victor Davis Hanson narrates a series of sieges and sackings that span the age of antiquity to the conquest of the New World to show how societies descend into barbarism and obliteration.

The dawn of 1945 finds a US Army at its peak in the Pacific. Allied victory over Japan is all but assured. The only question is how many more months—or years—of fight does the enemy have left. John C. McManus’s magisterial series, described by the Wall Street Journal as being “as vast and splendid as Rick Atkinson’s Pulitzer Prize-winning Liberation Trilogy,” returns with this brilliant final volume.

Hawaii, 1941. War clouds with Japan are gathering and the islands of Hawaii have become battlegrounds of spies, intelligence agents, and military officials - with the island's residents caught between them.

As the Allies raced to defeat Hitler, four men, all in the same unit, earned medal after medal for battlefield heroism. Maurice “Footsie” Britt, a former professional football player, became the very first American to receive every award for valor in a single war. Michael Daly was a West Point dropout who risked his neck over and over to keep his men alive. Keith Ware would one day become the first and only draftee in history to attain the rank of general before serving in Vietnam. In WWII, Ware owed his life to the finest soldier he ever commanded, a baby-faced Texan named Audie Murphy.
