If you happen to see American History magazine for June 2014 (the one with Custer on the cover), you could look inside at the "Departments" column. They have a quarter-page article about Arlington National Cemetery turning 150 years old.
And in that article, you will see a little photo of a young man, in bronze, lying dead.
I took that picture.
It's the top of the tomb of John Rodgers Meigs, the son of Brig. Gen. Montgomery C. Meigs. General Meigs founded Arlington National Cemetery, and was one of the greatest American civil engineers of the middle of the 1800s. His son died at the age of 21 near Harrisonburg, Virginia, in 1864. Meigs, a former best friend of Robert E. Lee's, considered his son's death to be murder, not war, due to the suspicious circumstances under which it occurred. General Phil Sheridan had the town of Dayton, Virginia, burned in retaliation for John Rodgers' death. Abraham Lincoln attended the young man's funeral at Oak Hill Cemetery in D.C. Later, Montgomery Meigs had his son's body moved to Arlington, and laid beneath a marble tomb with a bronze lid.
