I need help identifying the cavalry regiments and brigades engaged in this battle.

Thus far I have learned the 13th Va. Cav. of Beale's brigade was on picket when the feds began their movement on the 5th. They defended Malone's bridge against Gregg's cavalry. I found this information in the regimental history for the 13th that Harold Howard published.

I've also learned that the 9th and 10th arrived at dawn on the 7th of Feb. from Belfield and became engaged.

I don't know if Barringer's brigade of NC regiments fought at Hatcher's Run. He commanded the 1st, 2nd, 3rd and 5th regiments. Nor do I know if dearin'g sbrigade was engaged. He commanded the 4th nc cav. and the 16th nc cav. battalion.
