Days went on, and by the middle of April the Confederate government found itself forced to a fatal choice. Either it must begin war, or allow the rebellion to collapse. All its claims to independence were denied; the commissioner it sent to Washington on the pretense that they were agents of a foreign country were politely refused a hearing, yet not one angry word, or provoking threat, or a single harmful act had come from the "Black Republican" President. In his inaugural he had promised the people of the South peace and protection, and offered them the benefit of the mails. Even now, all he proposed to do was to send bread to Anderson and his hungry soldiers. His prudent policy placed them where, as he had told them, they could have no war unless they themselves chose to begin it.

They did choose to begin it. The rebellion was the work of ambitious men, who had no mind to stop at that late day and see their labor go for nothing. The officer in charge of their batteries was ordered to open fire on Fort Sumter if Anderson refused to surrender; and in the dim light of dawn on April 12, 1861, just as the outline of Fort Sumter began to show itself against a brightening sky, the shot that opened the Civil War rose from a rebel battery and made its slow and graceful curve upon Sumter. Soon all the batteries were in action, and the fort was replying with a will. Anderson held out for a day and a half, until his cartridges were all used up, his flagstaff had been shot away, and the wooden buildings inside the fort were on fire. Then, as the ships with supplies had not yet arrived, and he had neither food nor ammunition, he was forced to surrender.
