While Lieutenant Brooke developed the Brooke Rifle, Lieutenant Catesby ap Roger Jones was tasked with the manufacturing. In Selma, Alabama, the Confederate Navy created a foundry to turn out these guns. Through their resourcefulness, a successful, efficient foundry was created from nothing. Throughout the war, over 70 Brooke Rifles were cast in Selma and an almost equal number cast at Tredegar Ironworks in Richmond. These guns were vital to Secretary Mallory’s layered defense of Southern ports and armed both the forts and ironclads.

Norfolk was captured after Union troops landed near modern day Chix Beach far from Confederate defenses. Local Confederate leadership panicked as Union troops advanced on Norfolk. Unable to evacuate CSS Virginia, the Confederate Navy blew her up to prevent capture.

The road to Richmond seemed open. In May 1862, the Union Navy attempted to steam up the James River to capture the city. The Union force had two non-ironclad ships and three ironclads: USS Monitor, USS Naugatuck, and USS Galena. They were surprised by the Brooke Rifles at Drewry’s Bluff that caused massive damage to Galena and Monitor. Galena was hit over 45 times and was badly damaged, including suffering 25 casualties. The guns at Drewry’s Bluff bought time for the Confederate Navy to obstruct the river with mines and ironclads. The James River defenses would not be challenged again until 1865.15

In March 1863, Union Admiral Farragut attempted to run up river past the guns of Port Hudson on the Mississippi with his fleet of seven non-ironclad ships. Restricted room to maneuver, the strong current, and heavy Confederate shore-based gunfire caused havoc in the Union fleet. Only two of Admiral Farragut’s ships succeeded in passing the batteries. Every ship ran aground at some point in the engagement. Admiral Farragut’s ships were lashed together in pairs to minimize the risk of ships being disabled by gunfire and left to their own devices. USS Hartford and USS Albatross led the fleet upriver and were the only two ships to reach their objective. The second pair ran aground, and the shock of the grounding broke them loose of each other, damaging their engines and causing them to drift down river. Shot from the batteries damaged the boilers on USS Richmond, while her partner, USS Genesee, couldn’t make headway against the current and drifted down river. The lone ship in the rear, USS Mississippi caught fire after being hit with heated shot that exploded when the fire reached her magazines.16 In April 1863, Admiral DuPont attempted to force his way past the forts and batteries of Charleston with a fleet of ironclads. After several hours of bombardment, he failed. His force sustained massive damage. Three ironclads were put out of action for weeks, and one, USS Keokuk, sank from damage sustained during the fight.17

These guns not only heavily damaged ships that tried to force the passage, but their large range kept the blockading ships at bay, increasing the ability of blockade runners to enter the port. Wilmington’s geography provides an excellent example of the impact of heavy guns. Fort Fisher was constructed of sand at the tip of Cape Fear, protecting the two inlets into the Cape Fear River. Because of the distance between the two inlets, the Union Navy had to blockade both entrances which required more ships. The heavy guns of Fort Fisher included a 150 pound Armstrong gun, Blakely and Brooke rifles, eight and ten-inch Columbiads, and several 32 pounders. The 150 pound Armstrong gun and Brooke Rifles out-ranged the weapons of the blockading fleet by over a mile, forcing the ships farther offshore and increasing the number of successful blockade runners.18

Mine Warfare

Admiral Farragut’s famous quip to, “damn the torpedoes, full speed ahead” may be considered rash. He lost one of his ironclads, USS Tecumseh to Confederate mines (which were known as torpedoes at the time) at Mobile. If the mines had not become waterlogged, he might have lost more ships. Throughout the war, Confederate mines sank 29 Union ships and damaged 14 more.19

Mines struck fear into the hearts of Union sailors and impacted operations for commanders less daring than Admiral Farragut. Commander Matthew Fontaine Maury and Brigadier General Gabriel Rains led the Navy and Army torpedo research and production teams. Commander Maury’s experiences as a scientist and with electricity and transatlantic telegraph cable led to the development of the electrically detonated underwater mine. General Rains’ experience came from creating landmines and explosive booby traps during the Seminole Wars. While mines were a success, they were not perfect. Confederate manufacturing and new technology meant many became waterlogged duds and did not detonate, saving many more Union ships from a watery grave.

Mines were a controversial weapon in the 1860s; many thought mines lacked chivalry. Admiral Farragut said, “Torpedoes are not so agreeable when used by both sides; therefore, I have reluctantly brought myself to it. I have always deemed it unworthy of a chivalrous nation, but it does not do to give your enemy such a decided superiority over you.” Confederate Secretary of War George Randolph thought they should be used as a means to defend rivers and ports, but not just to kill the enemy. The Confederate Navy created offensive mines called the spar torpedo, a mine attached to a pole controlled from a ship.

The CSS Hunley, one of the world’s first submarines, and the first to sink an enemy vessel in combat, sank the USS Houstonatonic on blockade duty off Charleston in 1864. In addition to submarines, the Confederates developed the David-class torpedo launch. They were not true submarines, but their low profile made them challenging to spot at night. Throughout 1863, CSS David conducted attacks on USS New Ironsides, Wabash, and Memphis. The submarines and torpedo launches forced the Union blockade to remain farther offshore from Charleston to minimize the risk of submerged torpedo attack.

Mines were effective by striking fear into the hearts of sailors and shaping the battlespace through deterrence. The presence of mines often persuaded Union admirals to not attack, earning effective sea denial for the Confederacy. Admiral Farragut’s famous line stands out because most admirals did not go full speed ahead – they stopped and sent boats to sweep for mines first or simply remained offshore.

Conclusion

Secretary Mallory’s Navy succeeded in its desperate struggle to defend land against sea. The Confederate trident approach succeeded at denying the Union Navy local sea control in the vicinity of key port cities and forced ships to often remain farther from the coast. The Confederate layered defenses enabled Confederate ports to remain open until the final collapse of the Confederacy. 

Despite an ever tightening blockade, the port of Wilmington blockade runners brought 3.5 million pounds of meat, 1.5 million pounds of lead, 2 million pounds of saltpeter, 500,000 pairs of shoes, 300,000 blankets, 50,000 rifles, and 43 cannon from Europe in the latter half of 1864. The Army of Northern Virginia and the Army of Tennessee received new uniforms and equipment that enabled them to continue the struggle. Fort Fisher, the gateway to Wilmington, was captured in January 1865 after two amphibious landings. The Army of Northern Virginia capitulated four months later.20

Today, the U.S. Navy is the largest in the world. However, it finds itself in another technological revolution similar to the rise of the ironclad. While it has the ships and assumes it has permanent sea control, rivals have heavily invested in the spiritual successor to the Brookes Rifle, the anti-ship cruise missile.

The U.S. Navy must learn from the Confederate example and create its own trident of technologies and tactics to out-compete rival advances. The U.S. Navy should rapidly construct new long range anti-ship cruise missiles (ASCMs) that out-range opponents, improve and revive mine-warfare forces, and think hard about what evolution flows from the modern range and defense of the aircraft carrier. In addition, these advances should be shared with allies, such as Japan and the Philippines, who could utilize new American-developed sea mines and ASCMs to deny an adversary sea control near their littorals. Mobile long-range ASCM batteries on the islands of Luzon and Palawan could close the entire South China Sea to an adversary, much like Russian coastal defense cruise missile sites in Crimea can contest much of the Black Sea.

Great power rivals understand that a fleet-on-fleet engagement against the U.S. Navy is incredibly risky and have developed alternatives, just like the Confederate Navy developed alternatives to a fleet-on-fleet engagement with the Union. Now it is the U.S. Navy’s turn to learn from history, and develop its own counter-punch to ensure it maintains permanent sea control and open sea lines of communication.
