Also why would they not train there slave patrols and militia units at all? That goes against all human reasoning. Confederates want to get better at what they do and take pride in “hard work”. Naturally they want to get better at catching slaves and fighting partisans in the country. They are being paid to do this and they probably develop as time progresses to something more then rag tag armed groups.
Slave patrols received no training. None. Zip. Zero. Nada. Ziltch. You may think that it "goes against all human reasoning", but that was the real slave patrols used successfully for decades. They didn't get paid, either, the slave patrol's only payoff was if they caught an escaped slave. You didn't have to know how to track, that's what the dogs were for. You didn't have to know how to fight, either, that is also what the dogs were for. Being on a slave patrol was usually a boring, unpaid waste of time - many poor whites had to be legally required to serve, No one would waste time or money trying to give them military training.
Fighting partisans would be the job of the actual Confederate army, not some local militia. Local militias were voluntary, poorly paid or unpaid, and poorly trained at best. If you try to use militias and slave patrols for the difficult and very dangerous job of hunting partisans, the possible outcomes are:
* The militia charges in and get wiped out.
* The militia refuses to take on organized partisans.
* The militia spends a few days "looking for" Unionists in places where they don't think there are any Unionists, then report the Unionists have escaped.
* The militia spends a few days "looking for" Unionists in places where they don't think there are any Unionists, then report there are no Unionists.
* The militia spends a few days "looking for" Unionists in places where they don't think there are any Unionists, get ambushed by Unionists, and flee.
* The militia ambushes and kills a couple of random poor white men that they don't like, steals anything that isn't nailed down, sets fire to their homes, and possibly rapes their women.
* The militia ambushes and kills a couple of random black men, steals anything that isn't nailed down, sets fire to their homes, and possibly rapes their women.
The CSA could easily arm them with military gear, weapons, some horses, and have them trained very regularly since many do this as a full time job now(poor whites need jobs).
Where is the Confederate government getting the money to afford giving state militia and even slave patrols military gear or weapons or horses or training. It will be expensive enough doing this for the actual standing army. Being in the state militia was not a full time job in peacetime and in wartime it was often a way of avoiding being in the real army. Being part of a slave patrol was not a job at all, let alone a full time job, it was a chore that men often had to be legally forced to do. Being a professional slave catcher was sometimes a full time job, but the skills it required would not give proper military training.
Some officers(Bedford Forest types) could be very willing to train these men.
Forrest didn't become a military success by using militia instead of real soldiers.
Training brutality might be extreme if someone like Bedford Forest or hotheaded aristocrats(training someone in a brutal fashion might be common but won’t drive away many volunteers if they are getting paid well especially since how harsh normal life makes this treatment seem more normal to them. Aristocrats don’t mind paying them a bit more if it helps keep the slaves on the plantation and unionist dealt with. All levels of government are likely to be fine with funding this since it’s in all their best interest). What their doing is wrong but they are going to try to do it in the most practical and efficient way. They are thugs but that doesn’t mean they can’t train and learn so they can get better at it.
Militia were volunteers who would never put up with this kind of training. Any officer who attempted brutal training would be "accidentally" shot. And the planters would want the real soldiers to do the job they were paid for, not waste money sending militia after partisans. Slave patrols were not paid. Their only payoff was if they caught an escaped slave.
Edit: you do realize slaves are often bred selectively by masters like animals. This means the most physically strong or fast are often forced to breed together so the master can have better laborers in the field. That makes them harder to catch when they escaped if your stupid about it. This stuff isn’t right but it does take skills of some sort. Imagine someone who desires freedom more then anything else and the fear of being caught would drive someone. Mix that with physical traits of selective breeding and constant labor in the field. These are people just like us. Me or you are going to do whatever it takes to put up as much of a fight as possible to be caught.
Horrific as actual slavery was, I know of no examples of Southern slave owners forcibly breeding their slaves to be stronger. The eugenics movement was still generations away. Southern slave owners certainly were not breeding slaves to be able to run faster. Even the toughest slave wasn't immune to bullets, Even the strongest slave couldn't win against a dog pack. Even the fastest slave couldn't outrun dogs or horses, let alone bullets. Almost every day they had to go out, the slave patrols encountered nothing but boredom. On the few days they did find an escaped slave, the only skill required was one of the slave patrol being barely sober enough to not fall off their horse and to call off the dogs before they crippled or killed an unarmed, malnourished, and exhausted man, woman, or child.
