My favorite quote lately still sums it up:
"
Ifs beat the Confederates..." U.S. Grant
You won't be able to convince those that have bought into the Southern Myth of anything but the surpremecy of the Southern Generals.
Grant explained away the myth of the Confederates being outnumber at places like Shiloh by pointing out the way both sides counted troops. The South only counted active fighting men in the engagement on the line... the North counted every last person collecting pay... the band, the cooks, the supply personel... etc... Grant points out that if you counted only active fighting personel like the south did... HE was outnumber at Shiloh!
It's no different today: how strong is a modern infantry division... depends on who you ask and what troops they count... Are you talking the front line guys or all the support personel required too?
Force A and Force B are suddenly at war. Force A is a continuation of an existing, successful, military organization. It has entire regular units available. Force B is still being organized.
The problem with this was that the Union force at the start of the war was NOT a continuation of an existing organization. Almost all the units were newly mustered and raised at the start... lacking decent equipment and any kind of training. The "professional" Union army was actaully left out for the most part at the start(don't have my books handy to quote the passages.) It was one of the major drawbacks to the Union force... the North did not integrate experienced troops with the new volunteer units. This was a major stumbling block and why the South had major success to start with... troop quality.
Read Grant's memiors on his intial troubles with the rabble he had to convert into fighting men out west. Then read Grant admit that he and his men were inexperienced when the were caught off guard at Shiloh. But what made him a great commander was how he was able to recover in a situation like this.
The pro-Union bias around here is simply amazing. If the Union leadership was what you think it was, the force disparities would have resulted in the war being over in 1862, perhaps 1863 at the latest. Grab some books, guys. Bias is no substitute for knowledge.
Read some books on just how poorly trained the Union forces where... It's not numbers alone that will win you the war... otherwise the Western block was in great peril vs the Soviets... You can have an very large force but if it does not have the will or training to fight a smaller force can and will defeat it. Hence part of the problem in the Eastern campaings early on. At least in the west... each battle Grant and others fought got them more experience and training... and since the forces were intially nearly equal in size, and the confederats where on the home turf, and the training lacked for the Union troops... It must stand to reason that the leadership exbited by the field commanders (not necessarily the rear commanders like Halleck) played a part in thier victories.
One last point by Grant... he points out that up until Shiloh he and many others felt it would be a short war and the South would lay down their arms soon... After Shiloh he wrote that he came to the realization that that was wrong and a lot more bloodshed would be needed to get the South to surrender. I think that infected the entire Union force... they were just not "into" it like the South was for some time. This equated into a lack of initiative by some commanders to attack... why some troops broke and ran so soon... etc...
