From Ghosts of Harpers Ferry by Stephen D. Brown
Hog Alley didn't get its name in a very pretty way.
During the John Brown raid, the first raider killed was a black man by the name of Dangerfield Newby. Dangerfield had been freed by his white father, but he had a wife and seven children held in slavery in Warrenton, Virginia. His wife's master had told him that for the sum of $1,500 he could buy his wife and his youngest baby, who had just started to crawl. Dangerfield earned that amount of money and went back to Warrenton to purchase his wife and baby, only to have his wife's master raise the price. The free black man then joined John Brown in the hope of freeing not only his wife and youngest baby, but his entire family.
There were a lot of guns in Harpers Ferry, since they were made in the town and stored in the 22 building armory complex near the train tracks. There was little ammunition for the guns, however, and townspeople would fire anything they could find for their guns. One man was shooting 6 inch spikes from his powder loaded gun.
When John Brown raided the town in October of 1859, it was one of those spikes that hit the throat of Dangerfield Newby. He was killed instantly.
The people of Harpers Ferry, frustrated and angered by John Brown and his raiders, took the body of Dangerfield Newby and stabbed it repeatedly with their rusty knives. They left the mutilated body in the alley to be eaten by the hungry hogs.
Some night, if you are walking down Hog Alley and see a man dressed in baggy trousers and an old slouched hat with a terrible scar across his throat, you will know you have met Dangerfield Newby. He is still roaming our streets, trying to free his family.
