Naturally, Mr. Dowdey addresses himself to the question of how it all happened. Here, although he is working ground familiar to most Civil War students, he brings to an encyclopaedic knowledge of the facts a freshness of insight that makes the story seem new. If the tale has been told before it easily bears retelling, and although he does not labor his point unduly Mr. Dowdey never loses sight of the fact that behind his account of troop movements, bloody combats, and the errors of commanding generals there lies a picture of the nation’s greatest war reaching and passing its high moment of change. Here, not quite recognized at the time, was the moment of crisis. After McClellan’s beaten army retired to Harrison’s Landing, there was a different kind of war.
