The Battle of Antietam was fought on September 17, 1862, and became known as the bloodiest day in American history. The battle, fought in a valley in western Maryland, ended the first major Confederate invasion of northern territory.

The heavy casualties on both sides shocked the nation, and from some standpoints it could have been seen as a draw. But President Lincoln considered it enough of a victory to feel that it gave him political backing to issue the Emancipation Proclamation. More »

 The Battle of Gettysburg, fought during the first three days of July 1863, proved to be the turning point of the Civil War. Robert E. Lee led an invasion of Pennsylvania which could have had disastrous consequences for the Union. But the defeat of Lee, and his retreat into Virginia, set the stage for the final bloody two years, and eventual outcome, of the war. More »

After years of moving toward war, the outbreak of actual hostilities began when forces of the newly formed Confederate government shelled a United States military outpost in the harbor of Charleston, South Carolina.

The attack on Fort Sumter did not matter much in a military sense, but it had profound consequences. Opinions had already been hardening during the secession crisis, but an actual attack on a government installation made it clear that the rebellion of the slave states would indeed lead to war.

The Battle of Bull Run, on July 21, 1861, was the first major engagement of the Civil War. In the summer of 1861, Confederate troops were massing in Virginia, and Union troops marched southward to fight them.

Many Americans, both in the North and in the South, believed that the conflict over secession might be settled with one decisive battle. And there were soldiers as well as spectators who wanted to see the war before it ended.

When the two armies met near Manassas, Virginia on a Sunday afternoon both sides committed a number of errors. And in the end, the Confederates managed to rally and defeat the northerners. A chaotic retreat back toward Washington, D.C. was humiliating.

After the Battle of Bull Run people began to realize that the Civil War would probably not end soon and the fighting would not be easy. More »

The Battle of Shiloh was fought in April 1862, and was the first enormous battle of the Civil War. During fighting spanning two days in a remote part of rural Tennessee, Union troops who had landed by steamboat slugged it out with Confederates who had marched to head off their invasion of the South.

The Union troops were almost driven back to the river at the end of the first day, but on the following morning a fierce counterattack drove the Confederates back. Shiloh was an early Union victory, and a Union commander, Ulysses S. Grant, gained considerable fame during the Shiloh campaign. More »

The Battle of Ball's Bluff was an early military blunder by Union forces early in the war. Northern troops who crossed the Potomac River and landed in Virginia were trapped and suffered heavy casualties.

The disaster had serious consequences as outrage on Capitol Hill led the U.S. Congress to form a committee to oversee the conduct of the war. The congressional committee would wield influence throughout the rest of the war, often vexing the Lincoln Administration. More »

The Battle of Fredericksburg, fought in Virginia at the end of 1862, was a bitter contest that exposed serious weaknesses in the Union Army.

The second year of the war had begun with some optimism, but as 1862 ended, it was clear that the war would not end quickly. And it would continue to be very costly. More »
