Reenactors fire a mid-19th-century cannon at the Chickamauga and Chattanooga National Military Park to punctuate a discussion of collecting antique cannon artillery. Discoveries include an 1826 Tennessee hunting horn; a Regency cellarette once owned by the poet Lord Byron; and an heirloom necklace whose centerpiece is a five-carat diamond, valued at $250,000.
