DECEMBER 10-12TH, 1864: The CSS Macon, CSS Sampson and CSS Resolute, under Flag Officer Hunter took Union shore batteries under fire at Tweedside on the Savannah River. Hunter attempted to run his gunboats downriver to join in the defense of Savannah, but was unable to pass the strong Federal batteries.
The Resolute was disable din this exchange of of fire December 12th, and was abandoned and captured. Recognizing that he could not get his remaining two vessels to Savannah, and having to destroy the railroad bridge over the Savannah River that he had been defending, Hunter took advantage of the unusually high water to move upstream to Augusta.
Also this date: The USS O.H. Lee captured the British schooner Sort off Anclote Keys, Florida, with cargo of cotton.
