Fort Robert Smalls
According to historic preservationist Eliza Smith Brown, during the American Civil War, civic leaders in Pittsburgh ordered the construction of defensive structures, including forts and redoubts, in response to the threatened invasion of Pennsylvania by Confederate troops in 1863. Fort Robert Smalls was one of two of those installations which were known to have been built by black workers on McGuire's Hill. It was named for Robert Smalls, a slave who commandeered a Confederate transport, the CSS "Planter", and brought his family and others to freedom in the north. Its "four-to-five-foot-high earthen embankments" survived at the top of McGuire's Hill at the mouth of Becks Run in Arlington Heights until their 1930 destruction to make way for public housing.
