It is difficult for a general history to maintain a central thesis and remain informative, and be entertaining. One of Catton’s gifts is that he does it quite well here.
Terrible Swift Sword picks up in the immediate aftermath of First Bull Run. Like The Coming Fury, it covers a bit more than a year of time (leaving the third book to do some heavy lifting). Overall, the focus remains on events and personalities, and gives good attention to many aspects of the war.
But from the first, it is obvious that Catton has something more to say. The particular period of time is chosen precisely because it is that period where the war aims of Lincoln shifted, clarified, and eventually expanded.
Lincoln, and most everyone else, would have been happy for the war to end quickly and with as little disruption to the country as possible. And the longer it went on the more disruption must inevitably follow.
Naturally, the biggest, most unavoidable disruption is to slavery. Lincoln disclaims any changes to slavery as a war goal, and has to override various field commanders who take matters into their own hands. But anywhere the Union army goes, slaves start showing up looking for protection. And the proximate cause of the war was the Republican promise to not let slavery extend into all the territories (an argument the South lost by the act of seceding). And one of the threads through the book is the move towards a bigger effect on slavery, and the book therefore ends shortly after Anteitam and the initial Emancipation Proclamation.
Along the way, we get all the major moves. We also get the smaller ones. Catton gives a good account of Island Number 10, which is too often overshadowed by Shiloh. We also see Lee’s first command in future West Virginia, and his time in charge of the coastal defenses south of Virginia. We of course also get the initial Union forays there. And we get some real sidelights. One entire subchapter is spent on smuggling and other activities transferring goods from the North to the South… and vice versa. He doesn’t try to get at any real numbers, but Catton points out that there had been one national economy at work, and suddenly declaring a border didn’t suddenly wipe out all the dependencies between the two. All the profiteering and such was inevitable when confronted with that reality.
Again, Catton does a great job covering the various parts of the war, and giving attention to all the major movements and the secondary ones as well. Combine this with especial attention to the tribulations of the government and McClellan, and that ever present pressure of what the government and the war is going to do about slavery, and you have a good book on a critical year of the ACW. Combine that with Catton’s excellent writing, and you have a great general-reader introduction to the subject.
