The resupply of Fort Sumter became the first crisis of the administration of the newly inaugurated U.S. President Abraham Lincoln following his victory in the election of November 6, 1860. He notified the Governor of South Carolina, Francis W. Pickens, that he was sending supply ships, which resulted in an ultimatum from the Confederate government for the immediate evacuation of Fort Sumter, which Major Anderson refused. Beginning at 4:30 a.m. on April 12, the Confederates bombarded the fort from artillery batteries surrounding the harbor. Although the Union garrison returned fire, they were significantly outgunned and, after 34 hours, Major Anderson agreed to evacuate. There were no deaths on either side as a direct result of this engagement, although a gun explosion during the surrender ceremonies on April 14 caused the death of two U.S. Army soldiers. The event often regarded as the "First Bloodshed of the Civil War" was the Baltimore riot of 1861, one week later.
