The first engagement in which William Cushing distinguished himself was at the battle of Crumpler’s Bluff, which was in Franklin, Virginia. Federal officers designed a combined army-navy operation against elements of Longstreet’s army camped near Franklin on the Blackwater River in October 1862. While Navy gunboats under the command of Charles Flusser made their difficult way up the narrow, twisty Blackwater, the army was supposed to attack overland from the other side. They didn’t, leaving the gunboats perilously exposed. Under deadly fire, Cushing freed a cannon that had been strapped to the deck and fired, breaking the confederate attack. The pictures give an idea of how twisty the river is. By the way–there’s no bluff in sight. And for the record, yes, that’s a sewage treatment plant downriver to the left.
