William Jasper was a noted American soldier in the Revolutionary War. He was a sergeant in the 2nd South Carolina Regiment.

The Battle of Sullivan's Island or the Battle of Fort Sullivan was fought on June 28, 1776, during the American Revolutionary War. It took place near Charleston, South Carolina, during the first British attempt to capture the city from American forces. It is also sometimes referred to as the first siege of Charleston, owing to a more successful British siege in 1780.
