Beauregard sent several cases of fine brandy and whiskey and boxes of cigars to Anderson and his officers at Ft. Sumter. Anderson ordered that the gifts be returned. By April the Union troops had positioned 60 guns, but they had insufficient men to operate them all. Of the three levels of fort, the second tier of casemated gun positions was unoccupied.
Beauregard made repeated demands that the Union force either surrender or withdraw and took steps to ensure that no supplies from the city were available to the defenders, whose food was running low. A trained military engineer, he built-up overwhelming strength to challenge Fort Sumter.
- Fort Moultrie had three 8-inch Columbiads. two 8-inch howitzers, five 32-pound smoothbores, and four 24-pounders. Outside of Moultrie were five 10-inch mortars, two 32-pounders, two 24-pounders, and a 9-inch Dahlgren smoothbore.
- The floating battery next to Fort Moultrie had two 42-pounders and two 32-pounders on a raft protected by iron shielding.
- Fort Johnson on James Island had one 24-pounder and four 10-inch mortars.
- At Cummings Point on Morris Island were stationed seven 10-inch mortars, two 42-pounders, an English Blakely rifled cannon, and three 8-inch Columbiads, the latter in the so-called Iron Battery, protected by a wooden shield faced with iron bars.
The Union garrison surrendered the fort to Confederate personnel at 2:30 p.m., April 14. No one from either side was killed during the bombardment.
Beauregard became the Confederacy's first national hero for his resounding victory of the Union troops. He was called to Richmond and on July 21, 1861, he was also victorious at the Bull's Run (First Manassas.) After that battle he advocated the use of a new battle flag, he had designed, the famous "Stars and Bars." It became the most famous flag of the South.
