The Single Banded Brooke Rifles of CSS Atlanta
Four Single-Banded Brooke Rifles manufactured by Tredegar in 1862 are displayed as trophies in Willard Park at the Washington Navy Yard. Together the four cannons are the complete main armament of the ironclad CSS Atlanta. Atlanta was converted into a casemate ironclad at Savannah in 1862-1863 from the British merchant steamship Fingal. She was captured after a 15-minute action against the monitors USS Weehawken and USS Nahant. Weehawken’s 15-Inch Dahlgren was able to cause significant damage to Atlanta. Atlanta’s own cannon did not succeed in hitting the monitors, and because Atlanta grounded, the two US Navy monitors were able to position themselves outside the arcs of fire of the Atlanta’s cannons.
The contrast between this engagement and the battle the previous year between USS Monitor and CSS Virginia underlines the power of the 15-Inch Dahlgren. USS Monitor’s two 11-Inch Dahlgrens had been unable to disable CSS Virginia just as Virginia’s two 7-Inch Brookes, two 6.4-Inch Brookes and six 9-Inch Dahlgrens had been similarly unable to disable Monitor. CSS Atlanta carried the same number of Brooke Rifles as Virginia. She had similar armor. The 15-Inch Dahlgren carried by Weehawken smashed through that armor.
After her capture, Atlanta was recommissioned into the United States Navy as USS Atlanta. She was rearmed with two 8-Inch Parrott Rifles and two 6.4-Inch Parrott Rifles. Her original Brooke Rifles were taken to the Washington Navy Yard, where they represent the majority of existent single-banded Brookes.
Three of the four Brookes have an engraving on their breech describing their capture. One of the 6.4-Inch Brookes reads: “Brooke 100Pdr Rifle from Rebel Ram Atlanta captured by US Monitor Weehawken Commodore John Rodgers .”
The weights of the four Brookes are stamped upon their breeches. The 7-Inch Brookes read 15,162 pounds and 15,315 pounds. The 6.4-Inch Brookes read 9,110 pounds and 9,120 pounds.
