They stayed awake because they were afraid of dying in the cold and exhaustion.
We can arrive at this answer because:
- After walking for miles in the cold, Eliezer and his father were pretty exhausted, like all prisoners.
- They saw many die of exhaustion while walking, but they also saw many die in the snow when they lay down to rest.
- They realized that the cold and tiredness could be a dangerous combination for life and so they decided to stay awake at any cost.
