I have just emailed my friend Alfred Young and asked him that very question

I will let you know via the message board what Alfred has to say about this

I found a marvelous account of a charge in column of fours made by the brigade in the early hours Of April 6, 1865 at Sailor’s Creek, Virginia

I also found in account of the brigade making a mounted charge against union cavalry on August 21, 1864 at Globe Tavern
