SAVANNAH, Ga. - A preservation effort is continuing in Savannah to protect the site of one of the largest slave sales in U.S. history, known as "The Weeping Time," where more than 400 enslaved men, women and children were sold in March 1859. The roughly 35-acre area off Old West Lathrop Avenue includes land where plantation owner Pierce Butler sold members of his enslaved family to pay gambling debts. Advocates say the site remains largely unmarked today, despite its historical significance.
