Disaster Shipwreck on the Potomac

They Didn’t Need to be There It was a calm, moonless night in late April 1865. Robert E. Lee had surrendered. Abraham Lincoln was dead. Assassin John Wilkes Booth and accomplice David Herold, previously hiding in the swamps of Southern Maryland, had crossed the Potomac River to safety. The barge Black Diamond was anchored with the Potomac Flotilla near Blackistone Lighthouse, hoping to prevent that crossing and catch the perpetrators. All onboard were unaware that they were too late. The steamer Massachusetts was running downriver carrying U.S. soldiers back to their regiments. By dawn, the Black Diamond was on the bottom of the river, the Massachusetts was crippled and eighty-seven men were dead. Author Karen E. Stone reveals the story of a heroic pursuit turned tragic.
