Civil War (Civil War Goes Global)

Civil War
The (American) Civil War was a conflict between the Confederacy and later Britain, and the United States and later Mexico.

Causes
Although there were many pressures building up prior to the war, the dam finally burst with the Confederate bombardment of Ft. Sumter. Lincoln declared war, and the Civil War had begun.

Antietam and British Intervention
After the Battle of Antietam, Britain decided to join the Confederacy. The Royal Navy was being deployed, making the Union blockade less effective. However, the Royal Navy had trouble with the US's ironclads.
