Your question about "Union Wagons Burned N. of Pine Bluff" is rather vague. Could you give a citation of what time period during the war that you are talking about so that maybe we could put your question into a context of what may have been going on at the time.
As I have said before there were raids by partisans groups throughout the period 1863 to 65. But, I am not aware of any particular incident of Union Wagons being burned "North" of Pine Bluff. There were hundreds of wagons burned during the retreat from Jenkins Ferry by the federal, because they slowed the yankees down.
