1862 battle of the American Civil War
The capture of New Orleans (April 25 – May 1, 1862) during the American Civil War was a turning point in the war that precipitated the capture of the Mississippi River. Having fought past Forts Jackson and St. Philip, the Union was unopposed in its capture of the city itself.
Many residents resented the controversial and confrontational administration of the city by its U.S. Army military governor. This capture of the largest Confederate city was a major turning point and an event of international importance. It also caught many Confederate generals by surprise who had planned for an attack from the north instead of from the Gulf of Mexico.
Background.
The history of New Orleans differs significantly with the histories of other cities that were included in the Confederate States of America. Because it was founded by the French and controlled by Spain for a time, New Orleans had a population who were mostly Catholic and had created a more cosmopolitan culture than in some of the Protestant-dominated states of the British colonies. Its population was highly diverse. At the time of the Civil War, much of the population was made up of French-speaking Creoles, refugees from Saint Domingue and the Haitian Revolution, enslaved and free Blacks of African and mixed descent, and recent Irish and German immigrants.
New Orleans had benefited more than some other cities by the domestic slave trade, Industrial Revolution, international trade, and geographical position. It was a major port near the mouth of the Mississippi River at the Gulf Coast. The river carried freight and traffic from a huge network of rivers and tributaries, making New Orleans one of the most significant transportation centers in the early United States before the establishment of railroad and road systems. Of particular significance were the inventions of the cotton gin in 1793 and steamboat in the early 19th century.
Before the steamboat, keelboat men bringing cargo downriver would break up their boats for lumber in New Orleans and travel overland back to Kentucky, Tennessee, Ohio, or Illinois to repeat the process. Steamboats had enough power to move upstream against the strong current of the Mississippi, making two-way trade possible between New Orleans and the cities in the interior river network of the Upper South and Midwest. After the end of the Napoleonic Wars in 1815, which greatly expanded international trade, and the development of the cotton gin, cotton became a valuable export product. It became a major part of the volume of cargo moved through the city.
Jacksonian democracy and manifest destiny.
A formative event in the early history of New Orleans was the 1815 Battle of New Orleans. Fought during the War of 1812, the battle's American victory led by General Andrew Jackson enhanced his political career. Along with Martin Van Buren, he founded the Democratic Party. Jackson began a new political movement now known as the Jacksonian democracy.
This new direction in American politics had a profound influence on the development of New Orleans and the American Southwest. One of these developments was the construction of Fort Jackson, Louisiana, a star fort suggested by and named after Jackson. This fortress was intended to support Fort St. Philip and bar the Mississippi Delta from invasion.
The presidents of the Jacksonian democracy supported the concept of manifest destiny, greatly expanding acquisition of territory in the American Southwest and the support of international trade, along with the expansion of slavery. This powerful political movement also produced sectional tension between the northern and southern portions of the United States, resulting in the creation of the Whig Party to oppose the new Democratic Party. As the political rivalry between the Jacksonian Democrats and the Whigs intensified, the Republican Party was founded, to counter the spread of slavery into states produced by territorial conquests of the Jacksonian Democrats. The victory of Abraham Lincoln, the Republican presidential candidate, in the election of 1860, resulted in the secession crisis and was a catalyst to the American Civil War.
By the year 1860, New Orleans was in a position of unprecedented economic, military, and political power. The Mexican–American War, along with the annexation of Texas, had made New Orleans even more of a springboard for expansion. The California Gold Rush contributed another share to local wealth. The electrical telegraph arrived in New Orleans in 1848, and the completion of the New Orleans, Jackson and Great Northern Railroad from New Orleans to Canton, Mississippi, a distance of over , added another dimension to local transportation.
The combination of all these factors resulted in an increase in the price of prime field hands of 21 per cent in 1848, and further increases as the value of the domestic slave trade grew through the 1850s. By 1860, New Orleans was one of the greatest ports in the world, with 33 different steamship lines and trade worth 500 million dollars passing through the city. As far as population, the city outnumbered any other city in the South, and was larger than the four next-largest Southern cities combined, with an estimated population of 168,675.
War and battle.
The election of Lincoln in 1860 inspired governor Thomas Overton Moore to interdict an effort to make New Orleans a “free city”, or neutral area in the conflict. A solid Democrat, Moore organized a movement that voted Louisiana out of the Union in a secession convention that represented only 5 percent of the citizens of Louisiana. Moore also ordered the Louisiana militia to seize the Federal arsenal at Baton Rouge, and the Federal forts (Fort Jackson and Fort St. Philip that blocked approach upriver to New Orleans, Fort Pike that guarded the entrance to Lake Pontchartrain, the New Orleans Barracks south of the city, and Fort Macomb, which guarded the Chef Menteur Pass). These military moves were ordered on January 8, 1861, before the secession convention. With military companies forming all over Louisiana, the convention voted Louisiana out of the Union 113 to 17. The outbreak of hostilities in the area of Fort Sumter, South Carolina, led to the story of New Orleans in the Civil War.
The Union's strategy was devised by Winfield Scott, whose "Anaconda Plan" called for the division of the Confederacy by seizing control of the Mississippi River. One of the first steps in such operations was the imposition of the Union blockade. After the blockade was established, a Confederate naval counterattack attempted to drive off the Union navy, resulting in the Battle of the Head of Passes. The Union countermove was to enter the mouth of the Mississippi River, ascend to New Orleans and capture the city, closing off the mouth of the Mississippi to Confederate shipping both from the Gulf and from Mississippi River ports still used by Confederate vessels. In mid-January 1862, Flag Officer David G. Farragut had undertaken this enterprise with his West Gulf Blockading Squadron. The way was soon open except the water passage past the two masonry forts held by Confederate artillery, Fort Jackson and Fort St. Philip, which were above the Head of Passes approximately downriver below New Orleans.
From April 18 to 28, Farragut bombarded and then fought his way past these forts in the Battle of Forts Jackson and St. Philip, managing to get thirteen of his fleet's ships upriver on April 24. Historian Allan Nevins argues the Confederate defenses were defective:
 Confederate leaders had made a tardy, ill-coordinated effort to muster at the river barrier. Fortunately for the Union, both the naval and military auxiliaries were weak. In all their work of defense, the Southerners had been hampered by poverty, disorganization, lack of skilled engineers and craftsmen, friction between State authorities and Richmond, and want of foresight.
Major General Mansfield Lovell, Commander of Department 1, Louisiana, was left with one tenable option after the Union Navy broke through the Confederate ring of fortifications and defense vessels guarding the lower Mississippi: evacuation. The inner ring of fortifications at Chalmette was intended only to resist ground troops and few of the gun batteries were aimed toward the river. Most of the artillery, ammunition, troops, and vessels in the area were committed to the Jackson/St. Phillips position. Once this defense was breached, only three thousand militiamen with sundry military supplies and armed with shotguns remained to face Union troops and warships. The city itself was a poor position to defend against a hostile fleet. With high water outside the levees, Union ships were elevated above the city and able to fire down into the streets and buildings below. Besides the ever-present danger of weather-caused breaks in the levees, now an even greater threat to New Orleans was the ability of the Union military to cause a break in a major levee that would lead to flooding most of the city, possibly destroying it within a day.
Lovell loaded his troops and supplies aboard the New Orleans, Jackson, and Great Northern railroad and sent them to Camp Moore, north. All artillery and munitions were sent to Vicksburg. Lovell then sent the last message to the War Department in Richmond, “The enemy has passed the forts. It is too late to send any guns here; they had better go to Vicksburg.” Military stores, ships, and warehouses were then burned. Anything considered useful to the Union, including thousands of bales of cotton, were thrown into the river.
Despite the complete vulnerability of the city, the citizens along with military and civil authorities remained defiant. At 2:00 p.m. on April 25, Admiral Farragut sent Captain Bailey, First Division Commander from the , to accept the surrender of the city. Armed mobs within the city defied the Union officers and marines sent to city hall. General Lovell and Mayor Monroe refused to surrender the city. William B. Mumford pulled down a Union flag raised over the former U.S. mint by marines of the and the mob destroyed it. Farragut did not destroy the city in response but moved upriver to subdue fortifications north of the city. On April 29, Farragut and 250 marines from the removed the Louisiana State flag from the City Hall. By May 2, U.S. Secretary of State William H. Seward declared New Orleans "recovered" and "mails are allowed to pass".
Occupation and pacification.
On May 1, 1862, Maj. Gen. Benjamin Butler occupied the city of New Orleans with an army of 5,000, facing no resistance. Butler was a former Democratic party official, lawyer, and state legislator. He was one of the first Major Generals of Volunteers of the Civil War appointed by Abraham Lincoln. He had gained glory as a Massachusetts state militia general who had anticipated the war and carefully prepared his six militia regiments for the conflict. At the start of hostilities he immediately marched to the relief of Washington, D.C., and, despite a lack of orders, had occupied and restored order to Baltimore, Maryland. As a reward Butler was made commander of Fortress Monroe, on the Virginia Peninsula. There he gained further political renown as the first to confiscate "fugitive slaves" as contraband of war. This practice was later made a policy of war by Congress. Due to these and other astute political maneuvers, Butler had been chosen to command the army expedition to New Orleans. Because of his lack of military experience and military success, many were happy to see him go.
Challenge of occupation.
The United States War Department under Edwin M. Stanton expected Butler to hold eastern Louisiana and the cities of Baton Rouge and New Orleans, maintain communications up river to Vicksburg, and support Farragut's forces for the siege of Vicksburg. In addition, the city of New Orleans itself was just as indefensible for the Union as for the Confederates. Surrounded by a fragile network of levees and lower in elevation than the river around it, New Orleans was extremely vulnerable to flooding, bombardment, and insurrection. In addition, the city was generally unhealthy and subject to devastating epidemics. Defense of the city against attacks from Confederate forces depended on an extensive outer ring of fortifications requiring a garrison of thousands of troops. As a conquered territory, Louisiana had a potential for becoming a serious logistical drain on Union forces, and an unsustainable front if contested by well-organized resistance movements. It was popularly assumed that the Confederacy would launch a major counteroffensive to retake New Orleans. As the largest population center of the Confederacy, and commanding formidable industrial and shipping resources, its
