During the Civil War, Volcano's gold served the Union - the Volcano Blues smuggled the cannon "Old Abe" to intimidate rebel sympathizers. The cannon was cast by Cyrus Alger & Co. in Boston in 1837 and is the first of two 6-pounders made on the same day to be stamped with serial number 4. The cannon was never fired. The other cannon still survives at Shiloh Battlefield and is called "Shiloh Sam". Abe is the only cannon of that age in the U.S. still on a nineteenth century wooden carriage, and has had an interesting history all on its own.
