NASHVILLE, Tenn. (AP) — Calling it a way for his city to acknowledge, atone and seek reconciliation for slavery, Nashville Mayor David Briley announced plans Tuesday to replace an unused minor league baseball stadium with a park commemorating an adjacent Civil War fort built by slaves.In his first major move as mayor, Briley said he'll seek $1 million in city money to demolish Greer Stadium. The dilapidated, graffiti-ridden ballpark sits next to what remains of Fort Negley, which more than 2,700 African-Americans helped build after Union forces occupied Nashville in 1862. About 600 to 800 of them died.Developers had planned to build a housing and entertainment complex where the 40-year-old stadium sits.
