During the eighteenth century several expeditions were fitted out by the Hudson Bay Company, and a good deal of exploration was done by the Russians. In 1728, Vitus Bering discovered the straits which now bear his name; and in 1742, Lieutenant Chelyuskin reached the most northerly point of Asia in 77° 34′ by sledges. In 1765, Admiral Tschitschagoff was sent by the Czarina Catharine of Russia with three vessels to Spitzbergen to sail towards the North Pole. He reached 80° 21′, but found it impossible to advance farther. The following year he reached 80° 28′. In 1770 the New Siberian Islands were discovered by Liakhof. In 1773, Constantine John Phipps, afterwards Lord Mulgrave, sailed with the _Racehorse_ and _Carcass_, with a view of reaching the North Pole. He reached 80° 37′, and visited some of the Seven Islands. He also mapped the north of Spitzbergen. In this expedition the great Horatio Nelson was captain’s coxswain on board the _Carcass_. In 1818, Captain Buchan in the _Dorothea_, and Lieutenant (afterwards Sir John) Franklin in the _Trent_, attained 80° 34′ north of Spitzbergen. In 1823, Clavering and Sabine, in the ship _Griper_, visited Spitzbergen, and while Sabine carried on magnetic observations on the inner Norway Island, Clavering went to sea and steered northwards, but did not get farther than 80° 20′. The edge of the ice had now been thoroughly examined between the coast of Greenland and Novaya Zemlya, and it became evident that the ice could not be pierced by a ship. It occurred to Sir John Franklin and Sir Edward Parry that the best way of reaching the Pole would be by means of sledging over the ice. Parry put his ideas into practice in 1827, when he undertook his well-known expedition in the _Hecla_. He had just returned from his third Arctic voyage in search of the North-West Passage. His fourth voyage was an important one, and will be treated at some length in the first chapter. The Siege and Conquest of the North Pole CHAPTER I PARRY’S EXPEDITION OF 1827 In April 1826, Captain William Edward Parry proposed to Viscount Melville, First Lord Commissioner of the Admiralty, “to attempt to reach the North Pole, by means of travelling with sledge-boats over the ice, or through any spaces of open water that might occur.” The proposal was referred to the Royal Society, who strongly recommended its adoption; and an expedition having been equipped, Parry was appointed to the command of it.
