context_page_description: Yves-Joseph de Kerguelen-Trémarec was a French Navy officer. He is notable for discovering the Kerguelen Islands, and for authoring books about expeditions and about French naval operations during the American War of Independence. Welcomed as a hero after his First voyage of exploration, Kerguelen fell out of favour after his Second voyage and was cashiered for violating Navy regulations. He was rehabilitated during the French Revolution.
context_section_description: In 1767 he sailed near Rockall, or Rokol. Although he may not have approached within sight of it, or even within 150 miles, he appears to have had good information regarding it. His charted position for it was only 16 miles north of its actual position and he accurately described its appearance and the nearby Helen's Reef: "East of Rokol, ¼ league away, there is a submerged rock over which the water breaks". In 1771, he published a map of the area.
