"I called to the other men that the sky was clearing, and then a moment later realized that what I had seen was not a rift in the clouds but the white crest of an enormous wave. During 26 years experience of the ocean in all its moods I had not encountered a wave so gigantic.
“It was a mighty upheaval of ocean, a thing quite apart from the big white-capped seas that had been our tireless enemies for many days. I shouted, ‘For God’s sakes, hold on! It’s got us!’ ”
— Sir Ernest Shackleton, “South: A Memoir of the Endurance Voyage”
