The abandonment of the attack was a great disappointment to all hands. The men had worked long hours without thought of rest, and they deserved success. But the task was beyond our powers. I had not abandoned hope of getting clear, but was counting now on the possibility of having to spend a winter in the inhospitable arms of the pack. The sun, which had been above the horizon for two months, set at midnight on the 17th, and, although it would not disappear until April, its slanting rays warned us of the approach of winter.
