From The Boston Globe:
In the year 1755, a black slave named Mark Codman plotted to kill his abusive master. A God-fearing man, Codman had resolved to use poison, reasoning that if he could kill without shedding blood, it would be no sin. Arsenic in hand, he and two female slaves poisoned the tea and porridge of John Codman repeatedly. The plan worked — but like so many stories of slave rebellion, this one ended in brutal death for the slaves as well. After a trial by jury, Mark Codman was hanged, tarred, and then suspended in a metal gibbet on the main road to town, where his body remained for more than 20 years.
It sounds like a classic account of Southern slavery. But Codman’s body didn’t hang in Savannah, Ga.; it hung in present-day Somerville, Mass. And the reason we know just how long Mark the slave was left on view is that Paul Revere passed it on his midnight ride. In a fleeting mention from Revere’s account, the horseman described galloping past “Charlestown Neck, and got nearly opposite where Mark was hung in chains.” When it comes to slavery, the story that New England has long told itself goes like this: Slavery happened in the South, and it ended thanks to the North. Maybe we had a little slavery, early on. But it wasn’t real slavery. We never had many slaves, and the ones we did have were practically family. We let them marry, we taught them to read, and soon enough, we freed them. New England is the home of abolitionists and underground railroads. In the story of slavery — and by extension, the story of race and racism in modern-day America — we’re the heroes. Aren’t we?
