Harris was ship's mate and navigator aboard the logwood hauler Greyhound in January 1722 when it was seized by pirate George Lowther aboard the Happy Delivery between Honduras and Boston. The Greyhound’s captain Benjamin Edward fought Lowther for a time but eventually surrendered. In retaliation for their resistance the pirates killed many of the Greyhound’s crew; the remainder were forced aboard the Happy Delivery. Unlike most of the crew, Charles Harris willingly signed Lowther’s Articles to join his pirates. Lowther soon gave Harris command of a small prize ship, while granting another captaincy to Lowther’s own lieutenant Edward Low. Harris and Low sailed in concert with Lowther for a time; Harris’s ship was lost at sea and he came aboard Low’s ship. When Low deserted Lowther in May 1722, Harris left with him, along with Lowther’s quartermaster Francis Spriggs. Harris was with Low and Low's new quartermaster John Russell in June 1722 when they forced Philip Ashton into service; Ashton would become a famous castaway when he escaped from Low a year later. In July 1722 near Nova Scotia Low captured an 80-ton schooner which he renamed Fancy. Low took command of the Fancy and scuttled the Rebecca. Soon afterward they sailed for the Azores, where they captured a pink which Low took command of and renamed Rose Pink. While Low had the Rose Pink he gave command of the Fancy to Harris. Inexperience in careening led to the loss of the Rose Pink. Low took back the Fancy, sailing to Grenada and capturing a small ship named Squirrel then a French sloop renamed Ranger. Low gave the Squirrel to Francis Spriggs, who soon quarreled with Low and left the group. Low then gave the Ranger to Harris and they sailed for the Carolinas and up the American coast. Off Delaware Bay on June 10, 1723 Low and Harris pursued a fleeing merchantman. The vessel turned out to be the British 20-gun Man-of-WarGreyhound under Captain Peter Solgard. Low’s 70-man, 10-gun Fancy and Harris’ 50-man, 8-gun Ranger fought a lengthy running battle against the man-of-war, which chased them down via sail and oar. When the Ranger became crippled, Low abandoned Harris and escaped. One desperate pirate tried to blow up the Ranger rather than risk capture but was stopped and committed suicide instead. Harris and the survivors from Ranger were taken to stand trial in Newport, Rhode Island. Most were found guilty; amid a public spectacle, Harris and over 25 others were hanged July 19, 1723 after a lengthy sermon from Cotton Mather. To this day it remains the largest mass execution in Rhode Island history. Low, already notorious for his cruelty, was said to have become even more so after Harris' capture.
Flag
Harris flew the same “Jolly Roger” flag as Low and Spriggs. According to Captain Charles Johnson: And from a local newspaper article on execution day: Yet another source claims Harris's flag used the same design, but on a blue field instead of black:
