Explanation:
The Civil War began in Charlestown, South Carolina in 1861 when the Confederate troops in Charlestown fired on Fort Sumter.
As the article shows, they did this in response to the newly inaugurated president, Abraham Lincoln, stating that he would be sending 3 ships to the fort to resupply it, peacefully if he could but if force was required, it would be meted out.
The troops therefore fired on the fort to ensure that the Union do not resupply it and have a foothold in the Confederacy.
