These 12 facts might give you a new perspective on the Civil War

The American Civil War was a bloody, brutal time in the history of the United States. It not only pitted "brother against brother," as the saying goes, it was a fight over the soul of the country for (at least) the next 150 years. But while most people know the broad brushstrokes of the war's causes and conflicts, there are some little known Civil War facts that for some might cast America's bloodiest war in a whole new light.

The opening salvos of the Civil War were fired during the siege of Fort Sumter in South Carolina. When P.G.T Beauregard accepted the surrender of the fort, there were zero fatalities on either side. When the Union troops lowered the American flag, they gave it a 100-gun salute.

An accidental discharge from a cannon firing that salute killed Pvt. Daniel Hough of the 1st U.S. Artillery.

While the opening shots of the war were in Charleston Harbor, the first major battle was fought nearly three months later at the First Battle of Bull Run, also known as "First Manassas." General Beauregard used the house of Virginian Wilmer McLean as his headquarters during the fight. McLean moved his family away from the area shortly after to a two-story house at a place called Appomattox Court House.

It was at McLean's house that Gens. Grant and Lee met to discuss the South's surrender on April 9th, 1865.

The bulk of the Union troops were city dwellers and townspeople. When they talked about a battle, the notable things they saw were the natural features of the battlefield. Confederates were by and large from rural areas. When they remember a battle, their inclination is to talk about the manufactured, populated, or otherwise man-made features of the area.

For example, both times the two forces met near Manassas Rail Station, the Southerners dubbed the fights First and Second Battle of Manassas, while the Union troops named it after Bull Run, the nearby stream. At least 230 such Civil War combat actions are known to have multiple names.

When black soldiers began enlisting in 1863, they were paid $10 while white troops were paid $13 (officers, naturally, earned more). The black troops were also charged a monthly fee for their uniforms. They refused to be paid unequal wages by not accepting their pay at all – but still fought with valor the whole time.

In 1864, Congress ordered they be paid equal wages, with full pay, retroactive to the start of their enlistment. In a seemingly odd historical contrast, black soldiers fighting for the South were paid equal wages from the start of the war.

It may surprise someone new to the history of the American Civil War that black men fought for the Confederacy, but it's true. An estimated 3,000 to 6,000 fought as soldiers while another 100,000 supported the armies of the South as laborers and teamsters (though their motivation is in dispute). By the end of the war, 10 percent of the Union Army and Navy was made up of black men.

Meanwhile, roughly 25 percent of recruits for the Union army were immigrants. By 1860, 13 percent of Americans were born overseas and 43 percent of the armed forces were either immigrants or the sons of immigrants. Foreigners lined up at U.S. diplomatic legations abroad to join the Union cause — so many that the U.S. minister to Berlin had to put a sign up to tell people his office was not a recruiter, for example.

President Lincoln outlawed slavery in U.S. territories in 1862. He freed slaves who had masters in the Confederate Army. In 1863, the Emancipation Proclamation freed slaves held in rebel states. The President worked to eliminate slavery from the U.S. in the most piecemeal fashion he could. There was no formal law abolishing slavery until the passage of the 13th Amendment, which outlawed slavery — except by punishment of a crime.

The 13th Amendment was passed on January 31, 1865, but that didn't end slavery there. For an amendment to be added to the Constitution, it must be ratified by three-fourths of the States – including those in rebellion. When the war ended in April 1865, the amendment needed 27 of the 36 states, but only had 22. Georgia became the 27th when it ratified the 13th amendment on December 6th, 1865. About 45,000 slaves were freed in the last two slave states (Delaware and Kentucky) 12 days later.

The first-ever forced conscription in American history was enacted by the Confederacy. White men between ages 18 and 35 (and later, 45 as the war dragged on) had a three-year mandatory service obligation. The Confederate draft was very unpopular because it was viewed as a government violation of personal rights — the reason the South was fighting the Civil War.

In the North, the Enrollment Act allowed for able-bodied, military-age men to defer their service by paying for a substitute to take their place. The cost was $300 ($8,243.91 adjusted for inflation).

It was Sherman's capture of Atlanta that won Lincoln's re-election in 1864, ending the Democratic Party's call for peace talks. His March to the Sea and subsequent uncontested sweep through the Carolinas devastated the South and hastened the end of the war.

But in 1861, Sherman wasn't himself. When then-War Secretary Simon Cameron asked Sherman how many men he needed to defend the North, the general's request for 260,000 men caused Cameron to remove Sherman from command and send him to Kentucky under the command of a Brigadier of U.S. Volunteers, Ulysses S. Grant. Sherman had a nervous breakdown and was considered unfit for duty.

After Grant's rise to prominence in the Union Army, Sherman was moved to Grant's old command and the rest is history. When Congress moved to have Sherman elevated to Grant's position, Sherman wrote to them:

The Union, as any high school history class teaches us, was the manufacturing center of the United States in 1861, while the South had a mostly agrarian economy. With this industrial base, the North was able to produce the goods needed to fight the war while the South had to make do with what it could scrape together.

But history shows neither side could really afford the war. The Union's total income through taxes could only account for 15 percent of its spending. Even with increased tariffs, the first income tax, and other excises taxes, the Federal government only ever made a quarter of what it spent. The Union was forced to take on foreign debt to finance itself – $2.7 billion worth.

The South fared no better, of course. Its tax revenues only earned 11 percent of its fiscal needs. A third of its revenues came from printing money, as opposed to 18 percent in the North. Where the North's borrowed money would lead to a post-war boom, the interest on Confederate debt being bought in England and the Netherlands began to cost more than the war itself. Tax revenues in the South actually declined as the war continued.

An estimated 625,000 people were killed in the Civil War, and that number only includes those who died fighting. There an estimated 225,000 civilian casualties, which would set the total as high as 850,000.

The number one killer of Civil War troops was disease – the most prevalent were dysentery, typhoid fever, malaria, pneumonia, and simple childhood troubles like measles and mumps. Flies, mosquitoes, ticks, lice, maggots, and fleas were rampant and germ theory was not yet accepted medical practice.

The now-controversial and highly recognizable rebel flag, or "Dixie Flag," wasn't the official banner of the Confederate States of America. The crossed bar flag was actually just the battle flag of Robert E. Lee's Army of Northern Virginia.

A few states still base their flag on different iterations of the actual, official CSA flag, including North Carolina, Mississippi, Georgia, and Tennessee. The "Stars and Bars" flag that represented the Southern states features three bars and seven stars. The battle flag was used to make it easier to distinguish it from the North's flag in combat.

"Whenever there is no surviving spouse entitled to pension, the Secretary shall pay to the children of each Civil War veteran who met the service requirements of section 1532 of this title a pension at the monthly rate of $73.13 for one child." Thus reads the text of Title 38 of the U.S. Code regarding the rules for veterans' benefits to spouses and dependents of former soldiers.

In 2014, the Wall Street Journal found Irene Triplett, the 86-year-old daughter of Civil War veteran Mose Triplett (a rebel, in case you were curious, who deserted and joined the Union). Mose died in 1938, but his daughter continued receiving the $73.13 owed to her from Department of Veterans Affairs.

She is the last known Civil War beneficiary.
