They changed the link around a little, removing the Mass. Light Artillery flag and the U.S. flag captured by the 3rd Tenn. or I just can't find them again. http://historical.ha.com/common/view_item.php?Sale_No=6002&Lot_No=72045 this is one they kept.
Below is the description of the one captured by the 3rd. Is this one on your captured Union flag list?
Rare Pattern Character Laden 32-Star American Flag Captured at 1st Bull Run by Thomas Cawood, Co. K, 3d Tennessee Infantry (Mounted) CSA. Cawood served with the 3d Tennessee until his discharge in 1864 and was present at 1st Bull Run. The flag is 43” on the hoist and 57” on the fly, constructed entirely by hand of cotton, exhibiting several different weaves. Thirty one 13⁄4” cotton stars with the large central star measuring 6” from tip to tip, the canton being 221⁄2” x 24”. Although originally constructed with six, it retains vestiges of five blue silk ties. The flag is accompanied by a late twentieth century ink note that was apparently at one point attached to the flag which states, “This flag was picked up on the battlefield of the First Battle of Manassas (sic) in 1861. By Thomas Cawood, a Confederate soldier and presented to Camel E. Warren by John Cawood”, absolutely authentic and indigenous to this flag. The 32 star configuration was in use in 1858 - 59, with the admission of Minnesota. A number of small holes and one larger hole on the second white stripe, some tattering, primarily on the fly, obviously the result of honest use. Stars 100% intact, just some folding at the tips. Overall shows its great age but very sound with excellent color. Even retains two original tassels of four ply cotton cord.
The flag is accompanied by a detailed “Analysis Report” from noted conservator Fonda Thompson. The six-page. report is further accompanied by three pages of drawings. In addition to providing impeccable documentation of the flag’s authenticity, Ms. Thompson further states that, because of the unique detail of the insertion of the canton at the fourth white stripe, previously noted on only one other 32 star flag, with a purportedly indigenous to Minnesota, it is possible, if not likely, that this flag was carried into battle by the famed 1st Minnesota Infantry at First Manassas. A great flag with superb Civil War history and impeccable documentation. Estimate: $4,500 - $5,500.
