Was the attack on Fort Sumter a surprise attack?

it was a surprise attack because Lincoln told the Confederacy that he was sending food for his men but the south attacked them.

^- The south asked them to leave repeatedly. even said they would attack them if they wouldn't go, the people in Fort Sumter said they would leave if they didn't recive supplies. THEN lincoln sent them supplies. No it wasn't a surprise attack. they knew it was coming.
