What happened on February 22 during the US Civil War?

I go with all of the above!

I took the cop out of all of the above. Though if really pressed I would say that any time you can deny an enemy commerce you have weakened them militarily beyond any one engagement. You have weakened their ability to trade. No outbound trade, no inbound cashflow, no inbound cashflow, no spending, no spending, no munitions, no munitions, no ability to continue hostilities.

While the intel gained by the Union forces in the Battle of 1st Dalton was important, I believe the battle of Okolana, MS was more important strategically. The Battle of Okolona resulted in one hundred U.S. casualties and fifty Confederate, including the loss of Colonel Jeffrey Forrest, the brother of Nathan Bedford Forrest. Smith was reprimanded for disobeying his initial orders to start out for Meridian on February 1. Due to failing health Smith left the military in September 1864 and returned to civilian life. This action led to the loss of two officers who were not important by themselves but this chance battle helped pave the way to Sherman's march to the sea.
