As he was found on his death with a letter from the Chief Justice and Secretary of the Province of Carolina, Tobias Knight, in his possession and communicated with merchants, it is assumed that he could write and read which lead one author to theorise that Blackbeard was born into a wealthy family.
In May 1718, he formed an alliance of pirates and blockaded the port of Charleston, South Carolina (Aka Charles Town). All boacts were prevented from entering and leaving the port, as it had no guard ship. After successfully ransoming its inhabitants for medical suppliex by threatening to kill the prisoners of the nine ships captured, he then ran Queen Anne's Revenge aground on a sandbar near Beaufort, North Carolina. He parted company with Bonnet and settled in Bath Town, where he accepted a royal pardon but soon enough returned to the sea.
Despite being greatly romanticised after his death as a fierce and blood-thirsty pirate, there is no indication that he killed anyone; he was a shrewd and calculating leader, who often didn't use force but relied upon his reputation to get the desired responses from those he captured and robbed.
