American Civil War Part II

 Union blockade

By early 1861, General Winfield Scott had devised the Anaconda Plan to win the war with as little bloodshed as possible.  Scott argued that a Union blockade of the main ports would weaken the Confederate economy. Lincoln adopted parts of the plan, but he overruled Scott's caution about 90-day volunteers. Public opinion, however, demanded an immediate attack by the army to capture Richmond.

In April 1861, Lincoln announced the Union blockade of all Southern ports; commercial ships could not get insurance and regular traffic ended. The South blundered in embargoing cotton exports in 1861 before the blockade was effective; by the time they realized the mistake, it was too late. "King Cotton" was dead, as the South could export less than 10 percent of its cotton. The blockade shut down the ten Confederate seaports with railheads that moved almost all the cotton, especially New Orleans, Mobile, and Charleston. By June 1861, warships were stationed off the principal Southern ports, and a year later nearly 300 ships were in service.

Modern navy evolves

The Civil War occurred during the early stages of the industrial revolution and subsequently many naval innovations emerged during this time, most notably the advent of the ironclad warship. It began when the Confederacy, knowing they had to meet or match the Union's naval superiority, responded to the Union blockade by building or converting more than 130 vessels, including twenty-six ironclads and floating batteries.  Only half of these saw active service. Many were equipped with ram bows, creating "ram fever" among Union squadrons wherever they threatened. But in the face of overwhelming Union superiority and the Union's own ironclad warships, they were unsuccessful.

The Confederacy experimented with a submarine, which did not work well, and with building an ironclad ship, the CSS Virginia, which was based on rebuilding a sunken Union ship, the Merrimack. On its first foray on March 8, 1862, the Virginia decimated the Union's wooden fleet, but the next day the first Union ironclad, the USS Monitor, arrived to challenge it. The Battle of the Ironclads was a draw, but it marks the worldwide transition to ironclad warships.

The Confederacy lost the Virginia when the ship was scuttled to prevent capture, and the Union built many copies of the Monitor. Lacking the technology to build effective warships, the Confederacy attempted to obtain warships from Britain.

Blockade runners

British investors built small, fast, steam-driven blockade runners that traded arms and luxuries brought in from Britain through Bermuda, Cuba, and the Bahamas in return for high-priced cotton. The ships were so small that only a small amount of cotton went out. When the Union Navy seized a blockade runner, the ship and cargo were condemned as a Prize of War and sold, with the proceeds given to the Navy sailors; the captured crewmen were mostly British and they were simply released.  The Southern economy nearly collapsed during the war. There were multiple reasons for this: the severe deterioration of food supplies, especially in cities, the failure of Southern railroads, the loss of control of the main rivers, foraging by Northern armies, and the seizure of animals and crops by Confederate armies. Most historians agree that the blockade was a major factor in ruining the Confederate economy, however, Wise argues that the blockade runners provided just enough of a lifeline to allow Lee to continue fighting for additional months, thanks to fresh supplies of 400,000 rifles, lead, blankets, and boots that the homefront economy could no longer supply.

Economic impact

Surdam argues that the blockade was a powerful weapon that eventually ruined the Southern economy, at the cost of few lives in combat. Practically, the entire Confederate cotton crop was useless (although it was sold to Union traders), costing the Confederacy its main source of income. Critical imports were scarce and the coastal trade was largely ended as well.  The measure of the blockade's success was not the few ships that slipped through, but the thousands that never tried it. Merchant ships owned in Europe could not get insurance and were too slow to evade the blockade; they simply stopped calling at Confederate ports.

To fight an offensive war, the Confederacy purchased ships from Britain, converted them to warships, and raided American merchant ships in the Atlantic and Pacific oceans. Insurance rates skyrocketed and the American flag virtually disappeared from international waters. However, the same ships were reflagged with European flags and continued unmolested.  After the war, the U.S. demanded that Britain pay for the damage done, and Britain paid the U.S. $15 million in 1871.

Rivers

The 1862 Union strategy called for simultaneous advances along four axes. McClellan would lead the main thrust in Virginia towards Richmond. Ohio forces were to advance through Kentucky into Tennessee, the Missouri Department would drive south along the Mississippi River, and the westernmost attack would originate from Kansas.

Ulysses Grant used river transport and Andrew Foote’s gunboats of the Western Flotilla to threaten the Confederacy's "Gibraltar of the West" at Columbus, Kentucky. Grant was rebuffed at Belmont, but cut off Columbus. The Confederates, lacking their own gunboats, were forced to retreat and the Union took control of western Kentucky in March 1862.

In addition to ocean-going warships coming up the Mississippi, the Union Navy used timberclads, tinclads, and armored gunboats. Shipyards at Cairo, Illinois, and St. Louis built new boats or modified steamboats for action.  They took control of the Red, Tennessee, Cumberland, Mississippi, and Ohio rivers after victories at Fort Henry and Fort Donelson, and supplied Grant's forces as he moved into Tennessee. At Shiloh (Pittsburg Landing), in Tennessee in April 1862, the Confederates made a surprise attack that pushed Union forces against the river as night fell. Overnight, the Navy landed additional reinforcements, and Grant counter-attacked. Grant and the Union won a decisive victory – the first battle with the high casualty rates that would repeat over and over.  Memphis fell to Union forces and became a key base for further advances south along the Mississippi River. In April 1862, U.S. Naval forces under Farragut ran past Confederate defenses south of New Orleans. Confederates abandoned the city, which gave the Union a critical anchor in the Deep South.

Naval forces assisted Grant in his long, complex campaign that resulted in the surrender of Vicksburg in July 1863, and full Union control of the Mississippi soon after.

Eastern theater

In one of the first highly visible battles, a march by Union troops under the command of Maj. Gen. Irvin McDowell on the Confederate forces near Washington was repulsed.

Maj. Gen. George B. McClellan took command of the Union Army of the Potomac on July 26 (he was briefly general-in-chief of all the Union armies, but was subsequently relieved of that post in favor of Maj. Gen. Henry W. Halleck), and the war began in earnest in 1862. Upon the strong urging of President Lincoln to begin offensive operations, McClellan attacked Virginia in the spring of 1862 by way of the peninsula between the York River and James River, southeast of Richmond. Although McClellan's army reached the gates of Richmond in the Peninsula campaign.  Johnson halted his advance at the Battle of Seven Pines, then General Robert E. Lee and top subordinates James Longstreet and Stonewall Jackson defeated McClellan in the Seven Days Battles and forced his retreat.  The Northern Virginia Campaign, which included the Second Battle of Bull Run, ended in yet another victory for the South. McClellan resisted General-in-Chief Halleck's orders to send reinforcements to John Pope’s Union Army of Virginia, which made it easier for Lee's Confederates to defeat twice the number of combined enemy troops.

Emboldened by Second Bull Run, the Confederacy made its first invasion of the North. General Lee led 45,000 men of the Army of Northern Virginia across the Potomac River into Maryland on September 5. Lincoln then restored Pope's troops to McClellan. McClellan and Lee fought at the Battle of Antietam near Sharpsburg, Maryland, on September 17, 1862, the bloodiest single day in United States military history.  Lee's army, checked at last, returned to Virginia before McClellan could destroy it. Antietam is considered a Union victory because it halted Lee's invasion of the North and provided an opportunity for Lincoln to announce his Emancipation Proclamation.

When the cautious McClellan failed to follow up on Antietam, he was replaced by Maj. Gen. Ambrose Burnside. Burnside was soon defeated at the Battle of Fredericksburg on December 13, 1862, when more than 12,000 Union soldiers were killed or wounded during repeated futile frontal assaults against Marye's Heights. After the battle, Burnside was replaced by Maj. Gen. Joseph Hooker.

Hooker, too, proved unable to defeat Lee's army; despite outnumbering the Confederates by more than two to one, he was humiliated in the Battle of Chancellorsville in May 1863. Gen. Stonewall Jackson was shot in the arm by accidental friendly fire during the battle and subsequently died of complications. Gen. Hooker was replaced by Maj. Gen. George Meade during Lee's second invasion of the North, in June. Meade defeated Lee at the Battle of Gettysburg (July 1 to 3, 1863). this was the bloodiest battle of the war, and has been called the war's turning point. Pickett's Charge on July 3 is often considered the high-water mark of the Confederacy because it signaled the collapse of serious Confederate threats of victory. Lee's army suffered 28,000 casualties (versus Meade's 23,000). However, Lincoln was angry that Meade failed to intercept Lee's retreat, and after Meade's inconclusive fall campaign, Lincoln turned to the Western Theater for new leadership. At the same time, the Confederate stronghold of Vicksburg surrendered, giving the Union control of the Mississippi River, permanently isolating the western Confederacy, and producing the new leader Lincoln needed, Ulysses S. Grant.

Western theater

While the Confederate forces had numerous successes in the Eastern Theater, they were defeated many times in the West. They were driven from Missouri early in the war as a result of the Battle of Pea Ridge. Leonidas Polk's invasion of Columbus, Kentucky ended Kentucky's policy of neutrality and turned that state against the Confederacy. Nashville and central Tennessee fell to the Union early in 1862, leading to attrition of local food supplies and livestock and a breakdown in social organization.

The Mississippi was opened to Union traffic to the southern border of Tennessee with the taking of Island No. 10 and New Madrid, Missouri, and then Memphis, Tennessee. In April 1862, the Union Navy captured New Orleans, which allowed Union forces to begin moving up the Mississippi. Only the fortress city of Vicksburg, Mississippi, prevented Union control of the entire river.

General Braxton Bragg's second Confederate invasion of Kentucky ended with a meaningless victory over Maj. Gen. Don Carlos Buell at the Battle of Perryville, although Bragg was forced to end his attempt at invading Kentucky and retreat due to lack of support for the Confederacy in that state. Bragg was narrowly defeated by Maj. Gen. William Rosecrans at the Battle of Stones River in Tennessee.

The one clear Confederate victory in the West was the Battle of Chickamauga. Bragg, reinforced by Lt. Gen. James Longstreet's corps (from Lee's army in the east), defeated Rosecrans, despite the heroic defensive stand of Maj. Gen. George Henry Thomas. Rosecrans retreated to Chattanooga, which Bragg then besieged.

The Union's key strategist and tactician in the West was Ulysses S. Grant, who won victories at Forts Henry and Donelson (by which the Union seized control of the Tennessee and Cumberland Rivers); the Battle of Shiloh; and the Battle of Vicksburg, which cemented Union control of the Mississippi River and is considered one of the turning points of the war. Grant marched to the relief of Rosecrans and defeated Bragg at the Third Battle of Chattanooga, driving Confederate forces out of Tennessee and opening a route to Atlanta and the heart of the Confederacy.

Trans-Mississippi

Extensive guerrilla warfare characterized the trans-Mississippi region, as the Confederacy lacked the troops and the logistics to support regular armies that could challenge Union control. Roving Confederate bands such as Quantrill's Raiders terrorized the countryside, striking both military installations and civilian settlements. The "Sons of Liberty" and "Order of the American Knights" attacked pro-Union people, elected officeholders, and unarmed uniformed soldiers. These partisans could not be entirely driven out of the state of Missouri until an entire regular Union infantry division was engaged.

By 1864, these violent activities harmed the nationwide anti-war movement organizing against the re-election of Lincoln. Missouri not only stayed in the Union, Lincoln took 70 percent of the vote for re-election.

Numerous small-scale military actions south and west of Missouri sought to control Indian Territory and New Mexico Territory for the Union. The Union repulsed Confederate incursions into New Mexico in 1862 and the exiled Arizona government withdrew into Texas. In the Indian Territory, civil war broke out within tribes. About 12,000 Indian warriors fought for the Confederacy, and smaller numbers for the Union. The most prominent Cherokee was Brigadier General Stand Watie, the last Confederate general to surrender.

After the fall of Vicksburg in July 1863, General Kirby Smith in Texas was informed by Jefferson Davis that he could expect no further help from east of the Mississippi River. Although he lacked resources to beat Union armies, he built up a formidable arsenal at Tyler, along with his own Kirby Smithdom economy, a virtual "independent fiefdom" in Texas, including railroad construction and international smuggling. The Union in turn did not directly engage him. Its 1864 Red River Campaign to take Shreveport, Louisiana was a failure and Texas remained in Confederate hands throughout the war.

End of war

Conquest of Virginia

At the beginning of 1864, Lincoln made Grant commander of all Union armies. Grant made his headquarters with the Army of the Potomac, and put Maj. Gen. William Tecumseh Sherman in command of most of the western armies. Grant understood the concept of total war and believed, along with Lincoln and Sherman, that only the utter defeat of Confederate forces and their economic base would end the war. This was total war not in killing civilians but rather in taking provisions and forage and destroying homes, farms, and railroads, which Grant said "would otherwise have gone to the support of secession and rebellion. This policy I believe exercised a material influence in hastening the end." Grant devised a coordinated strategy that would strike at the entire Confederacy from multiple directions. Generals George Meade and Benjamin Butler were ordered to move against Lee near Richmond, General Franz Sigel (and later Philip Sheridan) were to attack the Shenandoah Valley, General Sherman was to capture Atlanta and march to the sea (the Atlantic Ocean), Generals George Crook and William W. Averell were to operate against railroad supply lines in West Virginia, and Maj. Gen. Nathaniel P. Banks was to capture Mobile, Alabama.

Grant's army set out on the Overland Campaign with the goal of drawing Lee into a defense of Richmond, where they would attempt to pin down and destroy the Confederate army. The Union army first attempted to maneuver past Lee and fought several battles, notably at the Wilderness, Spotsylvania, and Cold Harbor. These battles resulted in heavy losses on both sides, and forced Lee's Confederates to fall back repeatedly. An attempt to outflank Lee from the south failed under Butler, who was trapped inside the Bermuda Hundred river bend. Each battle resulted in setbacks for the Union that mirrored what they had suffered under prior generals, though unlike those prior generals, Grant fought on rather than retreat. Grant was tenacious and kept pressing Lee's Army of Northern Virginia back to Richmond. While Lee was preparing for an attack on Richmond, Grant unexpectedly turned south to cross the James River and began the protracted Siege of Petersburg, where the two armies engaged in trench warfare for over nine months.

Grant finally found a commander, General Philip Sheridan, aggressive enough to prevail in the Valley Campaigns of 1864. Sheridan was initially repelled at the Battle of New Market by former U.S. Vice President and Confederate Gen. John C. Breckinridge. The Battle of New Market was the Confederacy's last major victory of the war. After redoubling his efforts, Sheridan defeated Maj. Gen. Jubal A. Early in a series of battles, including a final decisive defeat at the Battle of Cedar Creek. Sheridan then proceeded to destroy the agricultural base of the Shenandoah Valley, a strategy similar to the tactics Sherman later employed in Georgia.

Meanwhile, Sherman maneuvered from Chattanooga to Atlanta, defeating Confederate Generals Joseph E. Johnston and John Bell Hood along the way. The fall of Atlanta on September 2, 1864, guaranteed the reelection of Lincoln as president. Hood left the Atlanta area to swing around and menace Sherman's supply lines and invade Tennessee in the Franklin-Nashville Campaign. Union Maj. Gen. John Schofield defeated Hood at the Battle of Franklin, and George H. Thomas dealt Hood a massive defeat at the Battle of Nashville, effectively destroying Hood's army.

Leaving Atlanta, and his base of supplies, Sherman's army marched with an unknown destination, laying waste to about 20 percent of the farms in Georgia in his "March to the Sea". He reached the Atlantic Ocean at Savannah, Georgia in December 1864. Sherman's army was followed by thousands of freed slaves; there were no major battles along the March. Sherman turned north through South Carolina and North Carolina to approach the Confederate Virginia lines from the south, increasing the pressure on Lee's army.

Lee's army, thinned by desertion and casualties, was now much smaller than Grant's. One last Confederate attempt to break the Union hold on Petersburg failed at the decisive Battle of Five Forks (sometimes called "the Waterloo of the Confederacy") on April 1. This meant that the Union now controlled the entire perimeter surrounding Richmond-Petersburg, completely cutting it off from the Confederacy. Realizing that the capital was now lost, Lee decided to evacuate his army. The Confederate capital fell to the Union XXV Corps, composed of black troops. The remaining Confederate units fled west after a defeat at Sayler's Creek.

Confederacy surrenders

Initially, Lee did not intend to surrender, but planned to regroup at the village of Appomattox Court House, where supplies were to be waiting, and then continue the war. Grant chased Lee and got in front of him, so that when Lee's army reached Appomattox Court House, they were surrounded. After an initial battle, Lee decided that the fight was now hopeless, and surrendered his Army of Northern Virginia on April 9, 1865, at the McLean House. In an untraditional gesture and as a sign of Grant's respect and anticipation of peacefully restoring Confederate states to the Union, Lee was permitted to keep his sword and his horse, Traveller. On April 14, 1865, President Lincoln was shot by John Wilkes Booth, a Southern sympathizer. Lincoln died early the next morning, and Andrew Johnson became the president. Meanwhile, Confederate forces across the South surrendered as news of Lee's surrender reached them. On April 26, 1865, General Joseph E. Johnston surrendered nearly 90,000 men of the Army of Tennessee to Major General William T. Sherman at the Bennett Place near present-day Durham, North Carolina. It proved to be the largest surrender of Confederate forces, effectively bringing the war to an end. President Johnson officially declared a virtual end to the insurrection on May 9, 1865; President Jefferson Davis was captured the following day. On June 2, Kirby Smith officially surrendered his troops in the Trans-Mississippi Department. On June 23, Cherokee leader Stand Watie became the last Confederate General to surrender his forces.

Diplomacy

Though the Confederacy hoped that Britain and France would join them against the Union, this was never likely, and so they instead tried to bring Britain and France in as mediators. The Union, under Lincoln and Secretary of State William H. Seward worked to block this, and threatened war if any country officially recognized the existence of the Confederate States of America. In 1861, Southerners voluntarily embargoed cotton shipments, hoping to start an economic depression in Europe that would force Britain to enter the war to get cotton, but this did not work. Worse, Europe developed other cotton suppliers, which they found superior, hindering the South's recovery after the war.

Cotton diplomacy proved a failure as Europe had a surplus of cotton, while the 1860–62 crop failures in Europe made the North's grain exports of critical importance. It also helped to turn European opinion further away from the Confederacy. It was said that "King Corn was more powerful than King Cotton", as U.S. grain went from a quarter of the British import trade to almost half. When Britain did face a cotton shortage, it was temporary, being replaced by increased cultivation in Egypt and India. Meanwhile, the war created employment for arms makers, ironworkers, and British ships to transport weapons.

Lincoln's foreign policy was deficient in 1861 in terms of appealing to European public opinion. Diplomats had to explain that United States was not committed to the ending of slavery, but instead they repeated legalistic arguments about the unconstitutionality of secession. Confederate spokesman, on the other hand, were much more successful by ignoring slavery and instead focusing on their struggle for liberty, their commitment to free trade, and the essential role of cotton in the European economy. In addition, the European aristocracy (the dominant factor in every major country) was "absolutely gleeful in pronouncing the American debacle as proof that the entire experiment in popular government had failed. European government leaders welcomed the fragmentation of the ascendant American Republic."

U.S. minister to Britain Charles Francis Adams proved particularly adept and convinced Britain not to boldly challenge the blockade. The Confederacy purchased several warships from commercial shipbuilders in Britain (CSS Alabama, CSS Shenandoah, CSS Tennessee, CSS Tallahassee, CSS Florida, and some others). The most famous, the CSS Alabama did considerable damage and led to serious postwar disputes. However, public opinion against slavery created a political liability for European politicians, especially in Britain (which, through the Slavery Abolition Act of 1833, had begun to abolish slavery in most of her colonies in 1834).

War loomed in late 1861 between the U.S. and Britain over the Trent affair, involving the U.S. Navy's boarding of the British mail steamer Trent to seize two Confederate diplomats. However, London and Washington were able to smooth over the problem after Lincoln released the two. In 1862, the British considered mediation – though even such an offer would have risked war with the U.S. British Prime Minister Lord Palmerston reportedly read Uncle Tom's Cabin three times when deciding on this.

The Union victory in the Battle of Antietam caused them to delay this decision. The Emancipation Proclamation over time would reinforce the political liability of supporting the Confederacy. Despite sympathy for the Confederacy, France's own seizure of Mexico ultimately deterred them from war with the Union. Confederate offers late in the war to end slavery in return for diplomatic recognition were not seriously considered by London or Paris. After 1863, the Polish revolt against Russia further distracted the European powers, and ensured that they would remain neutral.
