Death and the Civil War (9pm, UNC-EX) - This "American Experience" documentary, based on historian Drew Gilpin Faust’s book "This Republic of Suffering," looks at how the nation was transformed by the staggering number of Civil War casualties. At the war's start, some predicted it would be a brief and bloodless affair, but by the war's end, an estimated 750,000 people were dead. On the main UNC-TV channel at 9 p.m., “ Marching Once More” documents more than 100 survivors of the Battle of the Bulge as they returned to Belgium and Luxembourg in 2004 to reflect on the brutal six-week battle that claimed 19,000 American lives. The locally produced documentary features Chris Christensen, a veteran from Southport, who fears once the ceremonies end, memories of the largest and deadliest military conflict in world history will also fade away. Check the schedule on the UNC-TV website for more airings of each program.
