At 4:30a.m. on April 12, Confederate forces fired the first of 4,000 shells at the fort; it fell the next day. The loss of Fort Sumter lit a patriotic fire under the North. On April 15, Lincoln called on the states to field 75,000 militiamen for 90days; impassioned Union states met the quotas quickly. On May 3, 1861, Lincoln called for an additional 42,000 volunteers for three years. Shortly after this, Virginia, Tennessee, Arkansas, and North Carolina seceded and joined the Confederacy. To reward Virginia, the Confederate capital was moved to Richmond.
