How many Confederate soldiers were killed in the Civil War?

The death and casualty statistics from the US Civil War have had many estimates. Some historians now claim the total deaths in the US Civil War reached 750,000. The usual number is around 620,000. With that said, most estimates on the deaths of Confederate soldiers range in the area of 250,000 or more. One obstacle in this measurement was that so many Confederate war records had been destroyed. It is worthwhile to note that diseases caused the majority of deaths.
