Louisiana in the American Civil War

• 1. Enslaved Majority And Free Black Communities

  ›

  By 1860, nearly half of Louisiana's population were enslaved African Americans. This demographic reality shaped the state's economy and social structure before the war began. The institution of slavery had been entrenched since the territory became a state in 1812. Enslaved people comprised the majority during earlier French and Spanish dominations in the eighteenth century. Yet Louisiana also hosted one of the largest free black populations in the entire United States. Much of the white population, especially those living in cities like New Orleans, supported the continuation of slavery. Pockets of support for the U.S. government existed among rural residents who opposed secession. These divisions would become critical as the conflict escalated.

• 2. Governor Moore And Failed Defense Strategies

  ›

  On the 8th of January 1861, Governor Thomas Overton Moore ordered militia to seize the U.S. arsenal at Baton Rouge. He also directed troops to occupy Fort Jackson and Fort St. Philip guarding New Orleans. A wealthy planter himself, Moore acted aggressively to engineer secession through a convention on January 23. Only five percent of the public was represented in that convention. State military actions occurred before secession was officially established, defying constitutional requirements for a popular referendum. Moore justified his defiance by stating he did not think it comported with honor for Louisiana to live under a Black Republican president. Confederate strategies included an unofficial cotton embargo hoping Britain would intervene. They issued letters of marque to privateers to sweep Union ships from the sea. The third strategy relied on pre-war masonry forts combined with new ironclad fleets. All three approaches failed completely against Union naval power.

• 3. Union Navy And The Capture Of New Orleans

  ›

  President Abraham Lincoln viewed control of the Mississippi River as the backbone of the Rebellion. If the river were secured, the Confederacy would be split in half. Lincoln backed Admiral David Dixon Porter's idea of advancing upriver to capture New Orleans. This move aimed to supply northern textile manufacturers with cotton while renewing trade exports. The U.S. Navy became both an invasion force and a transport system along the river. Union forces took the city on the 25th of April 1862. Because many residents held Union sympathies or compatible commercial interests, the government designated areas under its control as a state within the Union. These areas received elected representatives to Congress. For much of the war, both sides recognized distinct governors for their respective versions of Louisiana. New Orleans and thirteen named parishes remained exempt from the Emancipation Proclamation.

• 4. Confederate Generals From Louisiana

  ›

  Antebellum Louisianans P.G.T. Beauregard, Braxton Bragg, and Richard Taylor commanded significant independent armies during the conflict. Taylor's forces remained among the last active Confederate armies when the war closed. Henry Watkins Allen led a brigade before becoming Confederate Governor from 1864 to 1865. Randall L. Gibson served as a competent brigade commander then later became a postbellum U.S. Senator. Alfred Mouton died at the Battle of Mansfield while leading his unit. Harry T. Hays and Chatham Roberdeau Wheat commanded notable brigades including the celebrated Louisiana Tigers. Francis T. Nicholls lost his left foot at Chancellorsville after commanding the Pelican Brigade. St. John Lidell was a prominent brigade commander in the Army of Tennessee. Henry Gray, a wealthy plantation owner from Bienville Parish, became a brigadier general before election to the Second Confederate Congress. Albert Gallatin Blanchard stood out as a Confederate general born in Massachusetts. Governor Thomas Overton Moore held office until early 1864 but failed to secure strong defense for New Orleans.

• 5. Battles Along The Red River And Waterways

  ›

  Military engagements in Louisiana concentrated heavily along major waterways like the Red River Campaign. The state saw numerous battles listed in official records including Forts Jackson and St. Philip. Fighting occurred at Donaldsonville, Georgia Landing, and Fort Bisland. Irish Bend and Vermilion Bayou hosted significant clashes during the war. Plains Store and Port Hudson became sites of intense siege operations. Milliken's Bend and LaFourche Crossing witnessed repeated combat actions. Goodrich's Landing and Kock's Plantation were locations where Union forces engaged Confederates. Stirling's Plantation and Bayou Bourbeux also saw fighting. Henderson's Hill and Mansfield became key battlegrounds with Mansfield sometimes called Sabine Cross-Roads. Pleasant Hill and Blair's Landing marked additional points of conflict. Monett's Ferry and Calcasieu Pass experienced military activity. Yellow Bayou and Mansura rounds completed the list of recorded engagements. These battles reflected the strategic importance of controlling river access throughout the region.

• 6. Reconstruction And Political Restoration Process

  ›

  Following the Civil War, Louisiana fell under the Fifth Military District. The state met Reconstruction requirements by ratifying constitutional amendments abolishing slavery and granting citizenship to former slaves. Representatives from Louisiana were readmitted to Congress after these conditions were satisfied. Full restoration to the United States occurred on the 9th of July 1868. The Compromise of 1877 changed the political landscape significantly. Southern Democrats acknowledged Republican Rutherford B. Hayes as president in exchange for meeting certain demands. One demand involved removing all U.S. military forces from former Confederate states. At that time troops remained only in Louisiana, South Carolina, and Florida. The compromise led to their complete withdrawal from the entire region. This withdrawal ended federal oversight and allowed Southern Democrats to regain control over state governments.
