1741. James Cook led three great voyages, with goals such as discovering Terra Australis, observing the Transit of Venus and searching for the elusive North-West Passage, these voyages are considered to have contributed to world knowledge and science. In the late 18th century, during a four year voyage Captain George Vancouver made detailed maps of the Western Coastline of North America. In the 19th century Charles Darwin made further contributions to science during the second voyage of HMS Beagle. The Ross expedition to the Antarctic made several important discoveries in biology and zoology. Several of the Royal Navy's voyages ended in disaster such as those of Franklin and Scott. World Wars During the First World War, the Royal Navy's strength was mostly deployed at home in the Grand Fleet, confronting the German High Seas Fleet across the North Sea. Several inconclusive clashes took place between them, chiefly the Battle of Jutland in 1916. The British fighting advantage proved insurmountable, leading the High Seas Fleet to abandon any attempt to challenge British dominance. For its part, the Royal Navy under John Jellicoe also tried to avoid combat and remained in port at Scapa Flow for much of the war. This was contrary to widespread prewar expectations that in the event of a Continental conflict Britain would primarily provide naval support to the Entente Powers while sending at most only a small ground army. Nevertheless, the Royal Navy played an important role in securing the British Isles and the English Channel, notably ferrying the entire British Expeditionary Force to the Western Front without the loss of a single life at the beginning of the war. At the end of the war, the Royal Navy remained by far the world's most powerful navy. It was larger than the U.S. Navy and French Navy combined, and over twice as large as the Imperial Japanese Navy and Royal Italian Navy combined. Its former primary competitor the Imperial German Navy was destroyed at the end of the war. In the inter-war period, the Royal Navy was stripped of much of its power. The Washington and London Naval Treaties imposed the scrapping of some capital ships and limitations on new construction. The lack of an Imperial fortress in the region of Asia, the Indian Ocean and the Pacific Ocean was always to be a weakness throughout the nineteenth century as the former North American colonies that had
