Hmm, I’ve always been something of a low-grade Civil War buff. Even wrote a ten page paper on this very topic (relative competency of military leadership for north and south) . . . which, naturally, is nowhere to be found. Anyway. . .
In and of itself, the assertion that the North only won because of superior resources and manpower is accurate. The American Civil War was truly a total war, in which whomever could replace men and material the most efficiently and for the longest stretch of time would win. Barring a failure of will in the north to prosecute the war, a military victory for the CSA was realistically impossible.
Needless to say, however, it does not follow from this that the southern armies were better led. The CSA had certain advantages that help to explain the seeming abundance of improbable southern victories in the war’s first two years. (1) They were generally on the defensive, both strategically and tactically. Given Civil War-era tactical doctrine, this was preferable to the offense in most regards. (2) They were fighting on known ground, whereas the Union armies were relatively ignorant of the terrain. When Southern armies ventured north, they were usually defeated. (3) They had the benefit of interior lines. While coming up with supplies in the first place may have been more difficult for the south, moving them (and troops) around was frequently easier for them than for the north. (4) In the eastern theater, where Lee’s Army achieved the south’s most salient victories, the terrain is dominated by several east-west rivers that are a constant impediment to the attacker (in this case, the Union). In the west, where the rivers ran primarily north-south (thereby providing a valuable means of transportation of both men and material to an attacker), the north fared considerably better.
Then again, one would be hard-pressed to prove that the north didn’t have a glut of losers in high command positions. Halleck? Banks? Butler? All without a redeeming quality (militarily speaking). McClellan was a mixed bag; an excellent tactician and a walking boon to morale, he was hampered by a pathological, irrational, and counter-factual fear of superior Confederate numbers, causing him to be unbearably slow and indecisive. Longstreet would insist after the war that McClellan could have “taken Lee’s army and everything in it” at Antietam had he not held two whole corps in reserve. A cursory examination of the battle bears this out.
I maintain that the south’s surprising victories in the early part of the war were (A) heavily influenced by the four inherent advantages mentioned above and (B) largely an accident of superior organization in one specific theater. The Army of Northern Virginia was organized into just two (and, after Chancelorsville, three) corps. To command these corps, the thoroughly competent Lee chose the thoroughly competent Longstreet and the thoroughly brilliant Jackson. Lee could afford to trust his subordinates to carry out vague orders to the best of their ability and understanding of the battlefield. The Army of the Potomac, in contrast, had a constantly changing structure and command heirarchy that featured up to and including a dozen corps. By all indicators, finding competent corp commanders was incredibly difficult. Lee had only to find two. McClellan et al had to find a dozen; add to this a few unfortunate (mostly political) appointemts, as well as the inherent difficulty of managing so large a bureaucracy (particularly in the abscence of electricity), and you begin to get a sense of what The Army of the Potomac had to overcome, all while destroying an enemy army, invading a large nation, and finally conquering it. That they eventually did all of this is a testament to their ultimate competency.
Of course, in the west, (the meddlings of Halleck and the incompetency of Rosecrans aside) the southern generals were no macth for Grant, Sherman, and Thomas. Anyone who argues that southern generals were “better” than Union generals ought to take a long, hard look at Braxton Bragg.
Finally, even if we allow that the CSA Army and corps command was superior in the eastern theater to USA army and corps command, that has to be tempered by all other levels of military leadership. Lincoln was far preferable to Davis (yes, this mattered). More importantly, I would argue that Confederate military talent was relatively front-loaded. That is, the average competency of commanders below all but the highest of levels were not as skilled as their superiors, and that the CSA had a very difficult time finding young talent to replace losses among generals. Many southern generals proved to be increasingly incompetent with each successive promotion. John Bell Hood was an excellent division commander, a barely adequate corps commander, and a horrible army commander. Ewell and A.P. Hill made very good division commanders, but fared merely adequately in their first battle as corps commanders (Gettysburg), at least as compared to the standards set by Jackson.
The Union, by contrast, had several very young, very intelligent officers in surprisingly high level positions by the end of the war. Towards the end, they had weeded out the better part of their deadwood in division and corps level command. The ascendency of Grant, Sherman, Sheridan, Thomas, Meade and Hancock (to name a few) was the death knell for the CSA. Lincoln, at long last, had found men who would fight (and well). So:
– Much of the (perceived) CSA superiority had to do with terrain and other factors beyond anyone’s control.
– If there was a southern leadership advantage, it was exclusively in the east.
– If there was this advantage, it was primarily an advantage of only a handful of men over another handful.
– If there was then this advantage, it was temporary.
– Regardless, the North had a demonstrable advantage in the west (which was, strategically, more important than the east).
– Regardless, mean competency for generals of all stripes favored the Union by the end of the war (though this is admittedly hard to measure due to increasingly poor supply for the CSA).
Conclusion: On balance, over time, on average, a marginal-moderate Union advantage in competency of military leadership.
