The document summarizes the resources, strategies, and events leading up to the start of the American Civil War. The North had greater population, industry, and railroad infrastructure, while the South had superior military leadership. The North planned to blockade Southern ports and capture the Mississippi River and Richmond. The South aimed to wear down the North through defense and gain allies like England. Tensions escalated when Confederate forces bombarded Fort Sumter in Charleston Harbor, firing the first shots of the Civil War and leading the fort to surrender.
