An interesting statistic. I've heard many of those battle flags have been returned w/in the last 50 yrs. or so to the southern states from whence they came.
Many of them were held by the U.S. War Department. In 1905 over 500 flags were discovered in the basement of the War Department and President Theodore Roosevelt had them returned to their respective states. The Museum of the Confederacy received a large portion of those from Virginia that year and even more in 1906.
Another interesting fact about captured Confederate flags....the number stamped on the border - 195 in the case of the flag below- is the unique capture number. Assigned when the flag was presented to the US War Dept., stamped onto the flag, and used to catalog the captured flags.
"After the Civil War, 545 captured Confederate flags were held by the U.S. War Department in Washington, D.C. These flags were stenciled with a number in black ink and, in some cases, capture histories were handwritten on linen tags sewn onto the flag. Detailed records were kept so that the government could award the Congressional Medal of Honor for capturing an enemy flag."
"In 1905, Congress passed legislation returning the captured flags to the Southern States. The Museum of the Confederacy was the recipient of the Commonwealth of Virginia's 75 repatriated flags. In 1906, another 252 flags from unidentified Confederate units were also entrusted to the Museum, creating the world's largest collection of Wartime flags."
