"A Voyage Round the World" by William Betagh is an historical account written in the early 18th century. The narrative chronicles a significant maritime expedition that began in 1719, primarily focused on privateering against the Spanish in the South Seas. Betagh aims to give a truthful account of the voyage, contrasting it with what he describes as the deceptive narrative published by Captain George Shelvocke, the original commander of the expedition. The opening portion presents Betagh's intent to provide an accurate recounting of their voyage, which was undertaken by two ships—the "Success" and the "Speedwell". Betagh, serving as captain of marines aboard the "Speedwell", details the lead-up to the expedition, including disagreements among the ship's officers, particularly with the controversial figure of Shelvocke. He asserts that Shelvocke's poor conduct and mismanagement negatively impacted their mission and puts forward evidence from journals and witness accounts, expressing his dedication to restoring the honor of his compatriots and presenting a narrative that corrects the perceived wrongs attributed to their captain.
