Brother vs. Brother
The Civil War was fought between the American states.  The argument was over the right of the states to make their own decisions, including whether or not to own slaves.  Southern states, with plantations and slaves, were on one side of the battle.  Northern states, who opposed slavery or had no need for it, were on the other side.  Some states remained neutral on the issue.

In 1861 Louisiana seceded from the Union and joined the Confederate States of America.  Fifty-six thousand Louisianians joined the Confederate Army, while 10,000 more joined home guard units.  Louisianians also joined the Union ArmyÐ5,224 whites and 24,052 blacks.

The Civil War was also called the War Between the States.  Soldiers often found themselves fighting against former friends and neighbors, even brother against brother.
