The Chambersburg Civil War Seminars, sponsored by the Greater Chambersburg Chamber of Commerce and coordinated by Ted Alexander and Scott Anderson, are held three times yearly.  The summer seminar, held annually in July, commemorates the burning and rebirth of Chambersburg, Pennsylvania. Chambersburg was ransomed for $100,000 in gold or $500,000 in currency. When the residents did not make payment, General John McCausland ordered the town to be burned on July 30, 1864. Over 500 structures were destroyed, and Chambersburg became the only northern town burned during the Civil War.
