The history of black america began when a ship carrying 20 blacks landed in what city?

The Civil War began when Confederate General Pierre Beauregard opened fire upon Fort Sumter. They fired because Fort Sumter was in a confederate state. Along with the northwestern portion of Virginia, four of the five northernmost "slave states" did not secede, and became known as the Border States. Emboldened by Second Bull Run, the Confederacy made its first invasion of the North when General Robert E. Lee led 55,000 men of the Army of Northern Virginia across the Potomac River into Maryland. The Battle of Antietam near Sharpsburg, Maryland, on September 17 1862, was the bloodiest single day in American history. At the beginning of 1864, Lincoln made General Ulysses S. Grant commander of all Union armies. Sherman marched from Chattanooga to Atlanta, defeating Confederate Generals Joseph E. Johnston and John B. Hood. Sherman's army laid waste to about 20% of the farms in Georgia in his celebrated "March to the Sea", and reaching the Atlantic Ocean at Savannah in December 1864. Lee finally surrendered his Army of Northern Virginia on April 9, 1865, at Appomattox Court House.
