How did slaves help the Union army?
Slaves provided agricultural and industrial labor, constructed fortifications, repaired railroads, and freed up white men to serve as soldiers. Tens of thousands of slaves were used to build and repair fortifications and railroads, as haule , teamsters, ditch diggers, and assisting medical workers.
The reasons the actual soldiers who were African Americans fought for the Confederacy. Some were forced to do so by their owners, either because extra manpower was needed or because the owner could no longer fight and needed the slave to fight on his behalf.
The Second Confiscation and Militia Act of July 17, 1862, was the first step toward the enlistment of African Americans in the Union Army.
Altogether, 186,000 black soldiers served in the Union Army and another 29,000 served in the Navy, accounting for nearly 10 percent of all Union forces and 68,178 of the Union dead or missing. Twenty-four African Americans received the Congressional Medal of Honor for extraordinary bravery in battle.
However, Blacks still wanted to fight for the Union army in the Civil War! Many wanted to prove their manhood, some wanted to prove their equality to white men, and many wanted to fight for the freedom of their people.
Today, most professional historians agree with Stephens that slavery and the status of African Americans were at the heart of the crisis that plunged the U.S. into a civil war from 1861 to 1865.
Thousands of black Americans were forced to support the operations of the Confederate army as teamsters, cooks, body servants, and laborers. In 1863, more than 6,000 accompanied the 71,000 soldiers of the Army of Northern Virginia into Pennsylvania.
Although the attitudes of many white Union soldiers toward slavery and emancipation ranged from indifference to outright racial hostility, others viewed the issue as central to their participation in the war.
Though no one knows for sure, the number of slaves who fought and labored for the South was modest, estimated Stauffer. Blacks who shouldered arms for the Confederacy numbered more than 3,000 but fewer than 10,000, he said, among the hundreds of thousands of whites who served.
The North was fighting for reunification, and the South for independence. But as the war progressed, the Civil War gradually turned into a social, economic and political revolution with unforeseen consequences. The Union war effort expanded to include not only reunification, but also the abolition of slavery.
Was the union for slavery or slavery?
Confederates generally saw the Union as being opposed to slavery, occasionally referring to them as abolitionists, as in reference to the U.S. Navy as the "Abolition fleet" and the U.S. Army as the "Abolition forces".
Many of these men were unofficially allowed to enlist in the Union Army. After President Abraham Lincoln's Emancipation Proclamation, Jan. 1, 1863, Black Soldiers were officially allowed to participate in the war.

Slavery had stripped black men of their manhood, so the thinking went, making them dependent and irresponsible. These stereotypes led most whites to assume that a black man could never be trained to fight like a white soldier. During the early part of the war, President Lincoln opposed accepting blacks into the army.
How did Southerners react to Black troops fighting for the Union? They generally refused to recognize them as prisoners of war, and instead tried to treat them like "escaped slaves".
Others remained on their home plantations and farms but took advantage of the war to gain some measure of autonomy for their families. Slaves' wartime actions most often exhibited their strong desire for freedom, and even those who chose not to escape frequently welcomed the Union army as liberators.
The reality is that the North's opposition to slavery was based on political and anti-south sentiment, economic factors, racism, and the creation of a new American ideology.
For more than 80 years, people in the Northern and Southern states had been debating the issues that ultimately led to war: economic policies and practices, cultural values, the extent and reach of the Federal government, and, most importantly, the role of slavery within American society.
Ivory, gold and other trade resources attracted Europeans to West Africa. As demand for cheap labour to work on plantations in the Americas grew, people enslaved in West Africa became the most valuable 'commodity' for European traders. Slavery existed in Africa before Europeans arrived.
Because the climate and soil of the South were suitable for the cultivation of commercial (plantation) crops such as tobacco, rice, and indigo, slavery developed in the southern colonies on a much larger scale than in the northern colonies; the latter's labor needs were met primarily through the use of European ...
Some black Southerners aided the Confederacy. Most of these were forced to accompany their masters or were forced to toil behind the lines. Black men were not legally allowed to serve as combat soldiers in the Confederate Army--they were cooks, teamsters, and manual laborers.
How did the South argue for slavery?
They argued that ending slavery would greatly affect the economy of the South, which depended on slave labor. The cotton economy could be destroyed, the tobacco crop dry in the fields and rice would not be profitable.
Not until after the Emancipation Proclamation was in force as of January 1, 1863, did Union officers actively recruit African American soldiers, although some black men were unofficially part of segregated units in a few states.
The Proclamation freed only the slaves in the states in rebellion against the Federal government. It did not free the slaves held in Union states. At the end of the war on December 6, 1865 the US Congress passed the 13th Amendment to the Constitution which abolished slavery through the United States.
Volunteers began to respond, and in May 1863 the Government established the Bureau of Colored Troops to manage the burgeoning numbers of black soldiers. By the end of the Civil War, roughly 179,000 black men (10% of the Union Army) served as soldiers in the U.S. Army and another 19,000 served in the Navy.
What led to the outbreak of the bloodiest conflict in the history of North America? A common explanation is that the Civil War was fought over the moral issue of slavery. In fact, it was the economics of slavery and political control of that system that was central to the conflict.
The North wanted to block the spread of slavery. They were also concerned that an extra slave state would give the South a political advantage. The South thought new states should be free to allow slavery if they wanted.
McPherson states that Union soldiers fought to preserve the United States, as well as to end slavery, stating that: While restoration of the Union was the main goal for which they fought, they became convinced that this goal was unattainable without striking against slavery.
Historians disagree on who played the key role in emancipation. Enslaved men and women gained freedom for themselves by abandoning their owners, coming uninvited to Union lines, and assisting the Northern war effort as laborers, spies, guides, and eventually as soldiers.
During the Civil War, Harriet Tubman and other abolitionists worked with the Union Army to help slaves travel to the North once they came behind Union lines. Tubman also volunteered to help the Union Army gather intelligence behind Confederate enemy lines.
Both free and enslaved men fought for American independence and for the British attempt to squash the rebellion. Most black Americans supported the British for reasons we know, but many served with the Continental Army because they believed in what the revolution presumably stood for.
Did the Union want to abolish slavery?
The Union war effort expanded to include not only reunification, but also the abolition of slavery. To achieve emancipation, the Union had to invade the South, defeat the Confederate armies, and occupy the Southern territory.
Confederates generally saw the Union as being opposed to slavery, occasionally referring to them as abolitionists, as in reference to the U.S. Navy as the "Abolition fleet" and the U.S. Army as the "Abolition forces".
