The Civil War was marked by intense and frequent battles. Over four years, 237 named battles were fought, along with many smaller actions, often characterized by their bitter intensity and high casualties. Historian
John Keegan described it as "one of the most ferocious wars ever fought", where in many cases the only target was the enemy's soldiers.
Mobilization of 1863|alt=Building on fire as rioters look on, one holds a sign that says "no draft" As the Confederate states organized, the US Army numbered 16,000, while Northern governors began mobilizing their militias. The Confederate Congress authorized up to 100,000 troops in February. By May, Jefferson Davis was pushing for another 100,000 soldiers for one year or the duration, and the US Congress responded in kind. In the first year of the war, both sides had more volunteers than they could effectively train and equip. After the initial enthusiasm faded, relying on young men who came of age each year was not enough. Both sides enacted draft laws (conscription) to encourage or force volunteering, though relatively few were drafted. The Confederacy passed a draft law in April 1862 for men aged 18 to 35, with exemptions for overseers, government officials, and clergymen. The US Congress followed in July, authorizing a militia draft within states that could not meet their quota with volunteers. European
immigrants joined the Union Army in large numbers, including 177,000 born in Germany and 144,000 in Ireland. About 50,000 Canadians served, around 2,500 of whom were black. When the Emancipation Proclamation went into effect in January 1863, ex-slaves were energetically recruited to meet state quotas. States and local communities offered higher cash bonuses for white volunteers. Congress tightened the draft law in March 1863. Men selected in the draft could provide substitutes or, until mid-1864, pay commutation money. Many eligibles pooled their money to cover the cost of anyone drafted. Families used the substitute provision to select which man should go into the army and which should stay home. There was much evasion and resistance to the draft, especially in Catholic areas. The
New York City draft riots in July 1863 involved Irish immigrants who had been signed up as citizens to swell the vote of the
city's Democratic political machine, not realizing it made them liable for the draft. Of the 168,649 men procured for the Union through the draft, 117,986 were substitutes, leaving only 50,663 who were conscripted. At least 100,000 Southerners deserted, about 10 percent of the total. Southern desertion was high because many soldiers were more concerned about the fate of their local area than the Southern cause. In the North, "
bounty jumpers" enlisted to collect the generous bonus, deserted, then re-enlisted under a different name for a second bonus; 141 were caught and executed. but historian John Keegan concluded that each outmatched the French, Prussian, and Russian armies, and without the Atlantic, could have threatened any of them with defeat.
Southern Unionists , one of the founders of the
Free State of Jones Unionism was strong in certain areas within the Confederacy. As many as 100,000 men living in states under Confederate control served in the Union Army or pro-Union guerrilla groups. Although they came from all classes, most Southern Unionists differed socially, culturally, and economically from their region's dominant prewar, slave-owning planter class.
Prisoners At the beginning of the Civil War, a parole system operated, under which captives agreed not to fight until exchanged. They were held in camps run by their army, paid, but not allowed to perform any military duties. The system of exchanges collapsed in 1863 when the Confederacy refused to exchange black prisoners. After that, approximately 56,000 of the 409,000 POWs died in prisons, accounting for 10 percent of the conflict's fatalities.
Women Historian
Elizabeth D. Leonard writes that between 500 and 1,000 women enlisted as soldiers on both sides, disguised as men. Women also served as spies, resistance activists, nurses, and hospital personnel. Women served on the Union hospital ship
Red Rover and nursed Union and Confederate troops at field hospitals.
Mary Edwards Walker, the only woman ever to receive the
Medal of Honor, served in the Union Army and was given the medal for treating the wounded during the war. One woman, Jennie Hodgers, fought for the Union under the name Albert D. J. Cashier. After she returned to civilian life, she continued to live as a man until she died in 1915 at the age of 71.
Union During the war, women in the North advocated for social reforms and created
ladies' aid societies, also called soldiers' aid societies, which provided supplies to soldiers on the battlefield and cared for sick and wounded soldiers. Women in the North also held military rallies, village parades, and charity bazaars. was a women's rights activist and abolitionist. Women like
Susan B. Anthony saw that supporting the war effort was a way to pave the future for women's suffrage movements. In her appeal to Northern women's loyalty, Anthony challenged the inconsistencies of the nation's founding ideal and its actual practices concerning equality among women. Northern women during the Civil War also made great strides in the workforce, as they helped contribute to the war effort by stepping into roles that were traditionally held by men. While women rarely worked in factories before the war, many filled men's places as they felt they could erase some of the boundaries that separated them from male preserves of power. By entering these new environments, women made significant progress in the fight for women's equality in the workforce. Northern women were also essential in the wartime support, as they were active participants in the war narrative. While women were not allowed to fight on the battlefield in the Civil War, they exhibited a patriotism that gave them the strength to maintain courage for themselves as well as their households. other women decided to stay at the plantations and run the plantations themselves. Southern women became focused on keeping the economic structure of the South as they dealt with increasingly rebellious slaves. White Southern women struggled to maintain morale on the home front as they dealt with problems without men. Although Southern women were devoted to the Confederacy, many requested that their sons and husbands be discharged from the military to help them at home. Eliza Adams wrote to the Confederate government to appeal for exemptions for her sons' military service, as she had sent five sons and also sons-in-laws to fight for the Confederacy. Southern women were torn between their patriotic ideals and their daily realities of life on the home front.
Union Navy The
Union Navy in 1861 was relatively small but, by 1865, expanded rapidly to 6,000 officers, 45,000 sailors, and 671 vessels totaling 510,396 tons. Its mission was to blockade Confederate ports, control the river system, defend against Confederate raiders on the high seas, and be ready for a possible war with the British
Royal Navy. The main riverine war was fought in the West, where major rivers gave access to the Confederate heartland. The US Navy eventually controlled the Red, Tennessee, Cumberland, Mississippi, and Ohio rivers. In the East, the Navy shelled Confederate forts and supported coastal army operations. The Civil War occurred during the early stages of the
industrial revolution, leading to naval innovations, including the
ironclad warship. The Confederacy, recognizing the need to counter the Union's naval superiority, built or converted over 130 vessels, including 26 ironclads. Despite these efforts, Confederate ships were largely unsuccessful against Union ironclads. The Union Navy used timberclads, tinclads, and armored gunboats. Shipyards in
Cairo, Illinois, and
St. Louis built or modified
steamboats. The Confederacy experimented with the submarine , which proved unsuccessful, and with the ironclad , rebuilt from the sunken Union ship . On March 8, 1862,
Virginia inflicted significant damage on the Union's wooden fleet, but the next day, the first Union ironclad, , arrived to challenge it in the
Chesapeake Bay. The resulting three-hour
Battle of Hampton Roads was a draw, proving ironclads were effective warships. The Confederacy scuttled the
Virginia to prevent its capture, while the Union built many copies of the
Monitor. The Confederacy's efforts to obtain warships from
Great Britain failed, as Britain had no interest in selling warships to a nation at war with a stronger enemy and feared souring relations with the US.

Winfield Scott had devised the
Anaconda Plan to win the war with minimal bloodshed, calling for a blockade of the Confederacy to suffocate the South into surrender. Lincoln adopted parts of the plan but opted for a more active war strategy. In April 1861, Lincoln announced a blockade of all Southern ports; commercial ships could not get insurance, ending regular traffic. The South blundered by embargoing cotton exports before the blockade was fully effective; by the time they reversed this decision, it was too late. "
King Cotton" was dead, as the South could export less than 10% of its cotton. The blockade shut down the ten Confederate seaports with railheads that moved almost all the cotton. By June 1861, warships were stationed off the principal Southern ports, and a year later nearly 300 ships were in service.
Blockade runners off Charleston. Continuous blockade of all major ports was sustained by North's overwhelming war production. |alt=Panoramic view of ships in harbor during battle The Confederates began the war short on military supplies, which the agrarian South could not produce. Northern arms manufacturers were restricted by an embargo, ending existing and future contracts with the South. The Confederacy turned to foreign sources, connecting with financiers and companies like
S. Isaac, Campbell & Company and the
London Armoury Company in Britain, becoming the Confederacy's main source of arms. To transport arms safely to the Confederacy, British investors built small, fast, steam-driven
blockade runners that traded arms and supplies from Britain, through Bermuda, Cuba, and the Bahamas in exchange for high-priced cotton. Many were lightweight and designed for speed, only carrying small amounts of cotton back to England. When the Union Navy seized a blockade runner, the ship and cargo were condemned as a
prize of war and sold, with proceeds given to the Navy sailors; the captured crewmen, mostly British, were released.
Economic impact The Southern economy nearly collapsed during the war due to multiple factors, the most notable being severe food shortages, failing railroads, loss of control over key rivers, foraging by Northern armies, and the seizure of animals and crops by Confederate forces. Historians agree the blockade was a major factor in ruining the
Confederate economy; however, Wise argues blockade runners provided enough of a lifeline to allow Robert E. Lee, a Confederate general, to continue fighting for additional months, as a result of supplies that included 400,000 rifles, lead, blankets, and boots that Confederate economy could no longer supply. The Confederate cotton crop became nearly useless, which cut off the Confederacy's primary income source. Critical imports were scarce, and coastal trade also largely ended. The blockade's success was not measured by the few ships, which slipped through, but by the thousands that never tried. European merchant ships could not obtain insurance for their ships and transport, and were too slow to evade the blockade, leading them to cease docking in Confederate ports. To fight an offensive war, the Confederacy purchased arms in Britain and converted British-built ships into
commerce raiders, which targeted
United States Merchant Marine ships in the Atlantic and Pacific oceans. The Confederacy smuggled 600,000 arms, enabling it to continue fighting for two more years. As insurance rates soared, American-flagged ships largely ceased traveling in international waters, though some were reflagged with European flags, which allowed them to continue operating. After the conclusion of the Civil War, the US government demanded Britain reimburse it for the damage caused by blockade runners and raiders outfitted in British ports. Britain paid the US$15 million in 1871, which covered costs associated with commerce raiding but nothing more.
Diplomacy .
John Bull, at right, warns
Uncle Sam, "You do what's right, my son, or I'll blow you out of the water." Although the Confederacy hoped Britain and France would join them against the Union, this was never likely, so they sought to bring them in as mediators. The Union worked to block this and threatened war against any country that recognized the Confederacy. In 1861, Southerners voluntarily embargoed cotton shipments, hoping to start an economic depression in Europe that would force Britain to enter the war, but this failed. Worse, Europe turned to Egypt and India for cotton, which they found superior, hindering the South's postwar recovery. War loomed in late 1861 between the US and Britain over the
Trent Affair, which began when US Navy personnel boarded the British ship and seized two Confederate diplomats. However, London and Washington smoothed this over after Lincoln released the two men. In 1862, the British government considered mediating between the Union and Confederacy, though such an offer would have risked war with the US. British prime minister
Lord Palmerston reportedly read ''Uncle Tom's Cabin'' three times when deciding what his decision would be. Washington repeatedly protested France's violation of the
Monroe Doctrine. Despite sympathy for the Confederacy, France's seizure of Mexico deterred it 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 they remained neutral.
Russia supported the Union, largely because it believed the US counterbalanced its geopolitical rival, the UK. In 1863, the
Imperial Russian Navy's Baltic and Pacific fleets wintered in the American ports of New York and San Francisco, respectively. == Eastern theater ==
