Students analyze how the North's industrial and population advantages contrasted with the South's superior military leadership and defensive geographic position.

Section 1

Union Strategy: The Anaconda Plan

Key Idea

The Union entered the war with more people, factories, and resources. To use this advantage, leaders developed a strategy nicknamed the Anaconda Plan. The idea was to surround the Confederacy and squeeze it like a giant snake, cutting off its ability to fight.

The plan had three main goals. First, the powerful Union navy would blockade Southern ports to stop all trade. Second, the army would seize control of the Mississippi River, splitting the South in two. Finally, Union forces would capture the Confederate capital at Richmond, Virginia.

Section 2

The First Battle of Bull Run: A Reality Check

Key Idea

In the summer of 1861, many in the Union believed the war would be over quickly. A confident but untrained army marched toward Richmond, Virginia, expecting to capture the Confederate capital and end the rebellion in one swift stroke.

Near a stream called Bull Run, the two inexperienced armies clashed in the war's first major battle. After some early Union success, Confederate reinforcements arrived and turned the tide. The Union soldiers retreated in a panic, creating a scene of chaos.

Section 3

Turning Point: Antietam and the Emancipation Proclamation

Key Idea

In September 1862, Confederate General Robert E. Lee marched his army into Maryland, a Union state. Union forces met his army at Antietam Creek in what became the single bloodiest day of the war. The brutal battle forced Lee’s army to retreat back into Virginia.

This Union victory gave President Lincoln the confidence to act. He issued the Emancipation Proclamation, declaring that all enslaved people in the rebelling states were free. This powerful order changed the meaning of the war, turning it into a fight to end slavery.

Section 4

The High-Water Mark: The Battle of Gettysburg

Key Idea

In the summer of 1863, Confederate General Robert E. Lee marched his army north into Pennsylvania. The two sides clashed in a massive, three-day battle at the town of Gettysburg.

Union forces held a strong defensive position on the high ground. They successfully fought off Confederate attacks, including a final, disastrous assault known as Pickett’s Charge.
