Civil War cannonballs, swords and unexploded munition discovered in South Carolina river

Hundreds of Civil War relics were unearthed during the cleanup of a South Carolina river where Union troops dumped Confederate military equipment to deliver a demoralizing blow for rebel forces in the birthplace of the secessionist movement.

The artifacts were discovered while crews removed tar-like material from the Congaree River and bring new tangible evidence of Union Gen. William T. Sherman's ruthless Southern campaign toward the end of the Civil War. The remains are expected to find a safer home at the South Carolina Confederate Relic Room and Military Museum in the state capital of Columbia.

Historical finds include bullets, cannonballs and even swords, CBS affiliate WLTX reports.
