American Civil War Timeline
November 6, 1860
Abraham Lincoln, candidate of the antislavery Republican Party, is elected president. As a result, between December 1860 and April 1861, 11 Southern states secede from the Union.
February 4, 1861
Representatives of seceded states meet in Montgomery, Alabama, and form the Confederate States of America, electing Jefferson Davis as president. The CSA constitution ensures the extension of slavery into new states and territories.
April 12–14, 1861
The Confederate attack on Fort Sumter, a federal outpost in the harbor of Charleston, South Carolina, marks the first military engagement of the American Civil War. After some 34 hours of bombardment, the fort surrenders on April 13, and Federal troops evacuate the fort the next day.
July 21, 1861
The First Battle of Bull Run, or the First Battle of Manassas, takes place near Manassas in northern Virginia and ends in a Confederate rout of Union forces.
March 9, 1862
In the first battle of ironclad warships, the Merrimack (which had been rechristened by the Confederates as the Virginia) clashes with the Union Monitor. Although the Union navy blockades 3,500 miles (5,600 kilometers) of Confederate coastline during the war, the Confederates excel at running the blockade.
April 6–7, 1862
In a fierce battle at Shiloh, in southwestern Tennessee, Union forces rally from almost near defeat to drive back the Confederate army. Both sides are immobilized for the next three weeks because of the heavy casualties, including more than 13,000 on the Union side and more than 11,000 on the Confederate side.
September 17, 1862
The battle at Antietam, Maryland, is regarded as a Union victory in an otherwise bleak year for Union forces in the East. However, the casualties set a grisly record. In what marks the bloodiest single day of the war, the South loses 10,316 troops, and the North suffers casualties of 12,401. Following this battle, Lincoln shifts the focus of the war from preserving the Union to freeing enslaved people in the Confederacy.
January 1, 1863
Lincoln issues the Emancipation Proclamation. It states that “all persons held as slaves” within the rebellious states “are, and henceforward shall be free.” The proclamation also allows black men to serve in the Union army. Up until this time, the Confederate government and people had expected that the English and French governments would intervene on their side in the war, but the conversion of the struggle into a crusade against slavery makes European intervention impossible.
July 1–3, 1863
After invading the North, Confederate forces under General Robert E. Lee meet Union forces at Gettysburg, Pennsylvania. The battle rages over three days, involving heavy artillery duels and high casualties on both sides. The battle is considered a major turning point in the eastern theater. Lee withdraws and is forced to fight a defensive campaign for the rest of the war.
May–July 1863
In the western theater of the war, General Ulysses S. Grant lays siege to the Confederate stronghold of Vicksburg, Mississippi. The Confederates surrender on July 4. The victory leaves the Mississippi River completely under Union control and splits the Confederacy in half.
September 2, 1864
General William T. Sherman captures Atlanta, Georgia. Sherman adopts a strategy of “total war” on his march through Georgia and the Carolinas. His troops destroy crops, supplies, railroads, bridges, and many small industries to weaken support for the war.
April 1865
General Lee is surrounded by Grant’s forces in Virginia. He finally surrenders to Grant at Appomattox Court House on April 9.
April 14–15, 1865
On April 14 President Lincoln is shot in Ford’s Theatre in Washington, D.C., by John Wilkes Booth. The president dies on April 15. Vice President Andrew Johnson becomes president. The death of Lincoln will make reconciliation between the North and South more difficult.
