Military science is far from an exact science, as Grant, Rommel, Clausewitz, Tolstoy, and other chroniclers of war have long argued. The tide of battle often depends on human factors-bad information, miscalculations, happy guesses, thorough planning-and on quirks of weather, timing, or faulty equipment. By providing all relevant information that Napoleon, Lee, Washington, and Henry V had at the ready,Yours to Reason Why isolates the moments when it seemed that victory could go to either side, and analyzes the decisions at the scene of ten famous battles-from Hastings and Waterloo to Gettysburg and Anzio. You must decide if Napoleon advances into Belgium or stands on the defensive, when to hit the beach at Anzio with air support, whether you follow Stonewall Jackson's advice to attack aggressively at Chancellorsville. William Seymour provides hundreds of maps, detail on terrain and armaments, the psychologyof the generals, and complete information on troop strength and their readiness to fight. To enter these pages is to marshal famous armies, to be for a moment captain of their fates, and to match wits with the generals whose decisions made history.
