There seems to have been a lot of provocation between indigenous blacks and whites with a plenty of agitation by the carpet bagging Republicans. I had known for a long time that Longstreet intended to further his post War career by courting favor with those people, holding high public office while other duly elected former Confederates were run out by the Republican regime.
As for soldiers who served under Longstreet, the one foremost in my mind is my ancestor, Captain Sam Willson, who was a district judge in Woodville, Texas before and shortly after the War. He had to leave office because he could not or would not take the Iron Clad Oath. I do not imagine he condoned or even understood Longstreet's behavior in Louisiana.
