Arctic glaciers, now known by the name of Humboldt. The winter proved to be unusually cold, the temperature, from December to March inclusive, averaging fifty-four degrees below the freezing-point of water. Most fortunately the men remained in health, but Kane grieved over the loss of his dogs, only a dozen surviving out of the original eighty. In this contingency Kane decided to put his men in the field, and after two weeks of excessive cold, the temperature averaging seventy-seven degrees below freezing, a party was sent out while the mercury was yet frozen. Their orders were to reach Washington Land, about one hundred miles distant across the sea-ice. It soon became evident to Brooks, the commander of the party, that the journey was impossible of execution, and after eight marches, in which less than forty miles were traversed, he turned back on March 29, 1854. The cold that day was intense, about ninety degrees below freezing, and the next morning four men were frozen so badly that they could not walk. Only four men were left for work. The distance to the brig was thirty miles, while the intervening ice was so rough that they could not drag their disabled comrades. Hickey volunteered to remain, while Sontag, Ohlsen, and Petersen should go to the brig for help. The three men finally reached the Advance, but they were so physically exhausted and in such mental condition that they could not even indicate in what direction they had left their comrades. Kane appreciated the gravity of the situation and the necessity of prompt measures. A relief party was at once started, which Kane led himself, despite his impaired health, physical weakness, and general unfitness for such a desperate journey; as always, he spared not himself when danger threatened. Ohlsen, being the clearest-headed of the sledgemen, was put in a sleeping-bag and dragged on a sledge as a guide. Eighteen hours' travel were without tangible result; Kane fainted twice on the snow; his stoutest men were seized with trembling fits, and as yet no signs of the missing party. Fortunately Kane had taken the Eskimo, Hans Hendrik, whose keen eye discovered the track that led to the tent of the frozen men. They were alive, but crippled beyond the possibility of marching. The weather remained fine or all would have perished, and as it was, Hayes, the surgeon, in his report of their condition on reaching the brig, said: "I was startled by their ghastly appearance. When I hailed them they met me only with a vacant, wild stare. They were to a man delirious." Of the eight men only one returned sound; two shortly died, two others suffered amputations, and three escaped with temporary disabilities.
