Many of the underfed ponies died of exhaustion, disappeared in the night, or were lost at sea on the voyage to the South pole. Others met a grizzlier fate: some horses, battered and fatigued, were preyed upon by Scott's scant crew of dogs; and two of them fell victim to killer whales when they floated off on an ice flow and were unable to be recovered safely. (Captain L.E.G. Oates had been put in charge of the ponies. When they slipped into the water where killer whales were hungrily waiting, Oates reportedly killed the ponies with an axe and an ice pick, saying that he couldn't leave them to be eaten alive.)
