Book excerpt: One of the bloodiest and most bitterly fought battles of the Civil War took place at Shiloh Church (and Pittsburg Landing) on April 6-7, 1862. The Union, led by Ulysses S. Grant and William Tecumseh Sherman, held off a massive Confederate offensive led by Albert Sidney Johnston and P. G. T. Beauregard, paving the way for Union control of the Western Theater. When the fighting ended, nearly 20,000 soldiers were either dead or wounded, and the South had lost one of its ablest commanders in Johnston. Guide to the Battle of Shiloh combines eyewitness accounts of this Tennessee battle with explicit details about advances and retreats, leadership strategies, obstacles, achievements, and tactical blunders. In addition, it provides directions to key points on the battlefield as well as maps depicting the action and details of troop positions, roads, rivers, elevations, and tree lines as they were 130 years ago.
