Confederate Soldiers Were White??

I saw this item on Drudge today:

Vandals damaged the city's monument to Confederate soldiers by spraying black paint over the faces of statues representing four white rebel fighters.

A soldier sculpture, part of the Confederate Monument in Portsmouth, Va., is shown painted black on Monday, June 20, 2005.

The damage was discovered during the weekend at the memorial, which consists of a 56-foot-tall granite pillar surrounded by four metal figures representing the navy, cavalry, infantry and artillery branches of the Confederate military.

All are white.

What caught my eye was this first and last sentence in the excerpt, specifically the "four white rebel fighters" and the last sentence, "all are white". Were there a lot of black confederate soldiers that I missed in my studies about the Civil War? I sort of took it for granted that pretty much any Confederate soldier immortalized in a sculpture or artwork would be white. It seems like an odd thing to reference in the article.
