The British searching squadron, including the _Resolute_, the _Assistance_, the _Pioneer_, and the _Intrepid_, while wintering in the vicinity of Cornwallis Island and Griffith Island, had held frequent communication and planned for exploration journeys on sledges to be undertaken as early as possible the following spring. Before the winter became too severe, depots of provisions were established to be used by the sledging parties, and the men trained in sledge dragging and walking exercises that they might be in good physical condition when the time for a test of endurance should arrive. Under the direction of Captain Austin, detailed plans were formed for careful exploration of islands and lands along Parry Strait. To Captain Penny was entrusted the thorough search of Wellington Channel. As early as the 12th of April, 1851, the parties intended for the westward explorations, numbering one hundred and four men, proceeded under the command of Captain Ommaney to the northwest end of Griffith Island, and there the entire encampment was closely inspected by Captain Austin. [Illustration: E. K. KANE] The extraordinary records of the six “extended” parties, those with instructions to go the farthest possible distance, were as follows: First, the sledge _Reliance_, under Captain Ommaney, travelled on south shore, was absent sixty days, and covered four hundred and eighty miles, two hundred and five of which was previously unknown coast. Second, the sledge _True Blue_, under Lieutenant Osborn, travelled on the south shore, was absent fifty-eight days, covered five hundred and six miles, and discovered seventy miles of coast. The third sledge, _Enterprise_, under Lieutenant Brown, travelled on south shore, was absent forty-four days, and covered three hundred and seventy-five miles, including one hundred and fifty of previously unknown coast. The _True Blue_, making the most western point reached 103° 25´ west longitude, a point about halfway between Leopold Island and Point Turnagain on the American continent. Of the three parties designed for the search of the north shore, the first sledge, _Lady Franklin_, under command of Lieutenant Aldrich, was absent sixty-two days, covered five hundred and fifty miles, and discovered seventy miles of coast. The second sledge, _Perseverance_, under Lieutenant M’Clintock, was absent eighty days, and covered seven hundred and sixty miles, forty miles of which was previously undiscovered coast. The third sledge, _Resolute_, under Surgeon Bradford, was absent eighty days, and covered six hundred and sixty-nine miles, and discovered one hundred and thirty-five miles of coast.
