In the early months of the Civil War, the city of Tampa needed ammunition and other supplies to defend against attack but apparently was short on cash.
So it issued a promissory note for $299.58 to storekeeper Thomas Pugh Kennedy on June 21, 1861.
Kennedy's great-granddaughter says the city never made good on its loan. Now, Joan Kennedy Biddle and her family are suing to collect the payment plus 8 percent annual interest.
The total bill: $22.7-million.
