Use the map showing the locations of important Civil War battles to answer the question.

The map shows the location of five major battles of the Civil War. The Battle of Vicksburg is labeled as I and took place on the Mississippi River between Louisiana and Mississippi. The Battle of Atlanta is labeled as II and took plae in northern Georgia. The Battle of Antietam is labeled as III and took place in northern Maryland. The Battle of Gettysburg is labeled as IV and took place in southern Pennsylvania. The Battle of Fort Sumter is labeled as V and took place on the Atlantic Coast of South Carolina.

How did the outcomes of these battles and the geography of the surrounding areas affect the war?
A
.

Confederate victories at the Battles of Antietam and Gettysburg allowed the Confederacy to control strategic passes in the Appalachian Mountains.
B.

Union victories at the Battles of Vicksburg and Atlanta allowed the Union to disrupt major river and railroad Confederate supply lines.
C.

Union victories at the Battles of Vicksburg and Fort Sumter allowed the Union to control major waterways early in the Civil War.
D.

Confederate victories at the Battles of Fort Sumter and Atlanta allowed the Confederacy to move supplies from Charleston Harbor to the interior.

B.

Union victories at the Battles of Vicksburg and Atlanta allowed the Union to disrupt major river and railroad Confederate supply lines.

B.

Union victories at the Battles of Vicksburg and Atlanta allowed the Union to disrupt major river and railroad Confederate supply lines.

To answer the question, we need to analyze the outcomes of these battles and understand the geography of the surrounding areas.

First, let's look at the outcomes of the battles:

1. Battle of Vicksburg: This battle resulted in a Union victory, allowing the Union to gain control of the Mississippi River. This disrupted major river Confederate supply lines, as mentioned in option B.

2. Battle of Atlanta: This battle also resulted in a Union victory, giving the Union control over northern Georgia. This allowed them to disrupt major railroad Confederate supply lines, as mentioned in option B.

3. Battle of Antietam: This battle ended in a Confederate retreat, preventing the Confederacy from fully invading the North. It did not necessarily affect the Confederate control over strategic passes in the Appalachian Mountains, which is mentioned in option A.

4. Battle of Gettysburg: This battle resulted in a Union victory, halting the Confederate invasion of the North. It also did not affect the Confederate control over strategic passes in the Appalachian Mountains, which is mentioned in option A.

5. Battle of Fort Sumter: This battle resulted in a Confederate victory, allowing the Confederacy to maintain control over Charleston Harbor. However, it did not allow them to move supplies from Charleston Harbor to the interior as mentioned in option D.

Based on these considerations, the most accurate option is option B. Union victories at the Battles of Vicksburg and Atlanta allowed the Union to disrupt major river and railroad Confederate supply lines.

By analyzing the outcomes of battles and understanding the geography of the surrounding areas, we can make an informed decision about how they affected the Civil War.
