Inspired by the fact they that were homeward bound, the men worked with desperate energy, and camped only when they were ready to drop with exhaustion. The last part of the march was through deep snow, which sifted into every crevice of the men's garments, and, melting there from the heat of the body, saturated their clothing. The most essential rules for the safety of arctic sledgemen are the careful brushing of all snow from the garments before entering the tent and the replacing of the always damp foot-gear with dry socks. Exhausted and unadvised, most of the men sought refuge from the fearful cold by crawling unbrushed into their frozen sleeping-bags, without even removing their boots let alone their socks. That day of the march had been one of awful cold, the average temperature being more than seventy degrees below freezing, and the imprudent sledgemen paid that night the exacting penalty of their rash ignorance. The following morning the situation was hopeless unless help could be had from the brig. The feet of four of the men were so badly frozen that they could not even walk, much less drag the sledge. It was impossible for the four well men to haul their four disabled shipmates to the _Advance_, thirty miles distant. At the call for volunteers for the dangerous journey, which must be made in one march, all four of the well men responded, and astronomer Sonntag, with two Danes, Ohlsen and Petersen, made the journey. Irish Tommy, as the crew called Seaman Hickey, rebelled at first because he was not accepted, but his generous heart reconciled him to remaining when it was pointed out that his qualities as cook and as handy-man made him the best person to care for his crippled shipmates. Kane tells the story of the rescue in language that cannot be improved. "We were at work cheerfully, sewing on moccasins by the blaze of our lamps, when, toward midnight, we heard steps and the next minute Sonntag, Ohlsen, and Petersen came into the cabin, swollen, haggard, and hardly able to speak. They had left their companions in the ice, risking their own lives to bring us the news. Brooks, Baker, Wilson, and Pierre were all lying frozen and disabled. Where? They could not tell--somewhere in and among the hummocks to the north and east; it was drifting heavily around them when they parted." With impaired health, in feeble strength, ignoring the protests of his officers against such exposure, the heroic Kane waited not a moment, but decided to take the field and risk his life, if necessary, to rescue his crippled shipmates.
