Common Operational HeritageUnion and Confederate Navies: 

Common Operational Heritage Union and Confederate Navies War of 1812 — Coastal defense and commerce raiding: Fighting from an inferior position against an enemy that has “command of the sea”. 1815-1846 — Global deployments: Protection of American maritime commerce overseas. 1846-1848 — Mexican-American War U.S. Navy controls the seas throughout the war. Ports established on the Pacific Coast.

Naval Comparison: 

Naval Comparison The Confederate Navy Inferior naval strength. U.S. Navy traditions prior to the Mexican-American War - Defensive. Coastal defense. Commerce raiding (Guerre de course). The Union Navy Superior naval strength built up throughout the war. Royal Navy traditions and U.S. Navy traditions in the Mexican-American War - Offensive. Establish control of sea lines of communication. Blockade of enemy coast. Power projection through amphibious assault.

Slide18: 

Diplomacy

Diplomacy for the North: 

Diplomacy for the North Keep Great Britain truly neutral Reconcile the blockade of Southern ports with British freedom of trade. Problem: Strong pro-Confederacy sentiment in important segments of British policy-making elites.

Diplomacy for the South: 

Diplomacy for the South Win British recognition and naval aid. Problems: War is viewed as a rebellion - not a conflict between sovereign states. Outcome of the war is uncertain. Diplomatic inexperience and a weak State Department. Fallacy of the "King Cotton" thesis. Slavery 1861- The “Trent Affair” Union Navy violates neutral rights of British ship.

Outcome of Diplomacy: 

Outcome of Diplomacy Ultimately a Failure Naval Agent James Bulloch gets that aid - Commerce raiders (Alabama, Florida, Shenandoah) - Blockade Runners - Laird rams (clearly warships; blockade breakers) Battle of Antietam (September 1862), Emancipation Proclamation, and Charles F. Adams’ protests end aid.

Strategy: 

19 June 1864 Strategy

Union Naval Strategy: 

Union Naval Strategy Part of General Winfield Scott’s master “Anaconda Plan” for victory. Blockade the entire Confederate coast. Capture Southern ports for coal, water, food: bombardment and amphibious assaults. Control of Mississippi River. Vital line of communication for Confederacy. Cut off Texas, Arkansas and Louisiana. Riverine operations in western areas. Combined Army-Navy operations against Confederate forces. Union Army -- Capture Confederate capital at Richmond.

Confederate Naval Strategy: 

Confederate Naval Strategy Part of overall strategy of “Attrition Warfare”. Army will defend territory and threaten Washington. Coastal defense: Army forts and new naval weapons systems. Blockade-running: Attempt to continue commercial trade with Europe. Operations hurt by Southerners’ desires for luxury goods. Union blockade’s increasing effectiveness increases profits. Commerce raiding: Successful cruises divert Union ships from blockade duty. Privateers (1861): Declaration of Paris - 1856. Unable to secure prize courts (sovereignty problems).

Naval Administration in the North: 

Naval Administration in the North Union Secretary of the Navy Gideon Welles Rapid and massive ship-building program. Only 42 ships at the beginning of the war. 264 commissioned by December, 1861 Convened Ironclad Board, August 1861, to combat Virginia

Naval Administration in the South: 

Naval Administration in the South Confederate Secretary of the Navy Stephen Mallory Confederacy issues letters of marque to privateers. Attempts to use new technology to gain advantage. Conversion of older ships to armored “ironclads”. Re-emergence of the ram as a naval weapon.

Naval Administration in the South (cont’d): 

Naval Administration in the South (cont’d) James Bulloch attempts to gain British aid. Coordinates construction of warships in Great Britain. Questions of legality for a neutral power (Great Britain) Antietam (September 1862), Emancipation Proclamation, and Union protests end aid.

Naval Operations and Important Battles

Early Naval Operations: 

Early Naval Operations Norfolk Navy Yard Largest naval base and arsenal in the United States. Captured by Confederate forces on 21 April. USS Merrimack scuttled by retreating Union forces. Large number of guns captured by Confederates. Union blockade of the Confederacy: “Paper Blockade” needs to become real as soon as possible. Forward bases required for an effective blockade. Amphibious operations launched to seize bases in the South.

Battle of Port Royal: 

Battle of Port Royal Attempt to establish first Union base on Confederate territory at Port Royal Sound -- 7 November 1861. Commodore Stephen F. DuPont Superior naval gunfire: Directed against Confederate forts defending the Sound. Confederates abandon forts. Union soldiers and Marines land unopposed. Other Union amphibious operations will resemble Port Royal operation.

USS Monitor : 

USS Monitor Welles’ Ironclad Board John Ericcson’s Monitor Highly armored with low freeboard. Single turret mounting two Dahlgren guns. Moved to Norfolk area to engage Virginia. Pounded each other for four hours Tactical draw but a strategic Union victory - Confederate Navy unable to break the blockade of Norfolk.

Inland River Campaigns Combined Union Army - Navy offensives Goal: Control of the Mississippi River Navy gunboats and transports used to support Army Union forces advance down Tennessee and Cumberland Rivers to the Mississippi

Battle of Mobile Bay: 

Battle of Mobile Bay Union fleet commanded by David Glasgow Farragut. Confederate fleet commanded by Franklin Buchanan. Entrance to Mobile Bay heavily defended. Torpedo buoys placed in entrance to the Bay. Guns of Fort Morgan defend only open channel. Union fleet outnumbers and outguns the Confederate fleet waiting in Mobile Bay. Farragut positions “monitors” between the rest of his fleet and Fort Morgan. Brooklyn’s captain stops and blocks the channel. “Damn the torpedoes! Full speed ahead!”

Fort Fisher: 

Fort Fisher Combined Union Army-Navy operation. Union fleet commanded by David Dixon Porter. First assault fails - Christmas 1864. Second Assault Sailors and Marines attack the fort with Army forces. Only successful amphibious assault against a heavily defended fort. Heavy, constant, targeted naval gunfire necessary for success.

Confederate Commerce Raiders: 

Confederate Commerce Raiders Highly successful in the disruption of Union maritime commerce. Captain Raphael Semmes CSS Sumter CSS Alabama Captures 68 Union vessels. Sunk at Cherbourg, France in duel with USS Kearsarge.

Tactical Trends in the Civil War: 

Tactical Trends in the Civil War Introduction of “ironclads”: Strengths: Heavily armored for coastal assault. Weaknesses: Low mobility on the open ocean. Question of a fleet's ability to suppress coastal fortifications unanswered. Appreciation for combined (Army-Navy) operations. Proper planning and coordination essential for success.

Slide63: 

Overall Technological Advances

Technological Innovation: 

Technological Innovation North — Monitor Class Combination of steam, screw, armor, and a gun turret. Large numbers built. “Dahlgren Guns” effective at close range. Gives Union Navy the advantage on coastal and inland waterways. South CSS Virginia -- Steam power and iron armor. The “Davids” CSS Hunley - submarine. “Torpedoes” “Laird” rams.

CSS Hunley:

Conclusions: 

Conclusions Decline of U.S. Merchant Marines due in large to the obsolescent sailing vessels used. Northern success in application of British-like offensive naval warfare PLUS Failure of Southern commerce raiding to win the war at sea = QUESTION: Will American naval officers still regard commerce raiding as the proper strategy in time of war ??????? The “Alabama Claims” cause a lasting diplomatic debate with Great Britain.

Conclusions: 

Conclusions Union blockade sets a precedent that that Woodrow Wilson finds inconvenient in 1914-1917. Joint Navy-Army Operations reach an unprecedented level of high efficiency on the Mississippi River. Joint Ops reach high point in the second amphib landing at Fort Fisher, North Carolina, closing down the confederacy’s last open port supporting R. E. Lee’s Army.
