text:  At the fort , Moultrie ordered his men to concentrate their fire on the two large man @-@ of @-@ war ships , Bristol and Experiment , which took hit after hit from the fort 's guns . Chain shot fired at Bristol eventually destroyed much of her rigging and severely damaged both the <unk> and mizzenmasts . One round hit her quarterdeck , slightly wounding Parker in the knee and thigh . The shot also tore off part of his britches , leaving his backside exposed . By mid @-@ afternoon , the defenders were running out of gunpowder , and their fire was briefly suspended . However , Lee sent more ammunition and gunpowder over from the mainland , and the defenders resumed firing at the British ships ; Lee even briefly visited the fort late in the day , telling Colonel Moultrie , " I see you are doing very well here , you have no occasion for me , I will go up to the town again . " Admiral Parker eventually sought to destroy the fort 's walls with persistent broadside cannonades . This strategy failed due to the spongy nature of the palmetto wood used in its constructions ; the structure would quiver , and it absorbed the cannonballs rather than splintering . The exchange continued until around 9 : 00 pm , when darkness forced a cessation of hostilities , and the fleet finally withdrew out of range .
