At one point during the battle , the flag Moultrie had designed and raised over the fort was shot down . Sergeant William Jasper reportedly ran to the battlement and raised the flag again , holding it up and rallying the troops until a flag stand could be provided . He was credited by Moultrie with reviving the troops ' spirits , and later given commendations for bravery . A painting of this event ( pictured above ) depicts Jasper 's actions .
