Young People in the Civil War

I don't think that the age limit is correct because I don't think that kids should have to go through that punishment, when they see other people getting killed right next to them. They should also make it so that if they wanted to join the army the could but if they don't, they don't have to. And at the end of the war millions of kids were orphaned because they were forced to go in to the army, since their fathers or brothers went into the army too.
