(Long Post)
As far as historicity goes, I am no expert. Although I know more about the Civil War than 99% of people in the United States, I would probably put myself in the bottom 10% of the people on this board (you will notice that I don't post in the History forum, although I read it). Call it a Ken Burns level of historical knowledge. Consequently I tend toward less historicity in my games and play with the rules as given without much thought as to how well they reflect what actually happened. I am also a min-maxer, but a lazy one: If I am thinking about it or if I am taking my time I eke out every advantage allowed by the rules, but a lot of times I just don't bother. The time it takes to min-max acts as a limit on how much I abuse the system in practice, and I think that by design or not the way the game is set up lets us all play with the style we are most comfortable with. (I would switch out my Corp commanders if I had any spare ones for example, but since I play CSA it doesn't come up since I don't have enough for a carousel.)
So, from that perspective, cavalry:
The most important thing to know about the combat engine is that units target units, and they fight against each other for an entire phase. A unit is anything that has its own painting in the panel at the bottom of the screen when you click on a stack; in the battle report each unit has its own line. A division is a unit, a loose brigade is a unit, a single cav element sitting at the stack level is a unit. The reason I never leave single elements or brigades in a stack going into combat is because it is entirely possible that they will be selected by the engine to engage a full sized division for a round of combat. There is a smoothing out function in the engine that prevents a single element from randomly taking all the hits applied to the unit that round, so the more elements that a unit has, the more survivable each individual element is. A loose brigade or element in a stack during battle it doesn't have a lot of comrades to spread hits to, so they are concentrated on only a few elements, and can easily take enough hits to destroy elements which is how you lose VP and NM. Therefore, I always combine everything I can into divisions before a battle, even if it leaves a division in a suboptimal configuration.
In terms of Detect/Hide and Patrol/Evade, the location of the cavalry within the stack does not matter, only that they are IN the stack. So if you had the Laurel Brigade (a five element CSA Cav brigade) loose at the stack level, the stack would definitely gain every Detection, Patrol and (as far as I can tell) Pursuit benefit that you are entitled to from the cav. BUT, if you go into combat, and the brigade is engaged, it will be in much greater danger of losing elements, and be less effective in dealing hits to the enemy than if it were combined into a division (unless it happens to engage another loose brigade, but in practice, you will be facing divisions). Single element units get destroyed all the time this way once division formation is allowed. One place you can see this is during Assaults (the order, rather than the phase). You have a small division in the structure and one or two locked militia elements that cannot be combined into the division. Even though you win the battle without too much trouble, in the battle report afterward you can see that those lone militia are almost always destroyed: they counted as units and were targeted by an enemy division which was easily able to deal enough hits to wipe them out.
So, no, I don't advocate putting those cav brigades at the corps level, I would combine them into a division of some type to increase their survivability and effectiveness in battle. You get all the benefits to Detection, Patrol, etc. for less risk.
That being said, the Cav brigades are extremely valuable in their own right, but for an unrelated reason. I don't know about the Union force pool because I don't play as the Union, but as the CSA we do not get to build any, we only get them from scripts. If you look carefully you will see that many of them only require 0 or 1 command point despite the fact that they have between two and six elements in them. This makes them VERY useful as scouts, and I tend not to put them in combat situations because they cannot be rebuilt if they are completely destroyed. The Laurel Brigade, on the other hand requires 4 CP, so I always put it into a division somewhere.
I make two kinds of "Cav" divisions. The first is a 100% cav or Cav/HA division that I use to scout in the East or late-game-Midwest. It is not good in combat (it needs infantry) but is large enough to survive accidental contact with an enemy stack and is still fast and relatively stealthy. There isn't that much call for scouting in the East (as the CSA) because everything is close anyway, so I don't always have one of these. The second is a "mop up" division that includes 5 or 6 infantry and some rifled guns (because it will always need to be in attack posture where smoothbores are less effective). This is what I use to clean up enemy stacks that are retreating, low on cohesion and out of supply. They have enough Patrol to force the battle, have enough infantry to absorb hits and go toe-to-toe in the Range 0 phases, and then do a lot of pursuit hits when they win. 100% cav divisions just take WAY too many (expensive) hits when used in this role.
I don't always have either type formed up depending on what is going on, I just form them as needed. The nice thing about a "mop up" division is that it can be formed with two or three infantry-cav brigades, the Laurel Brigade (which needs to go into a division anyway) and some 10lbers and then left alone for the rest of the game: with a cav leader it is really effective in Corps vs Corps combat, and is easily detached and sent off on clean-up missions when needed. If you need to do some scouting with it you can always strip out the artillery and the infantry brigades, add in a couple of independent cav elements and away you go. I use a setup similar to this in MO but with Mounted Infantry rather than vanilla infantry to hunt down those stray brigades Athena always leaves wandering around (minipol originally suggested that, it works great).
