From Twenty Years Before the Mast, by Charles Erskine (Fossil, 2016), Kindle pp. 69-70:
January 20. At two o’clock this morning the sun and moon appeared above the horizon at the same time, but in opposite directions. The moon was full. The effect of the sun shedding his deep golden rays on the distant icy mountains and the surrounding icebergs was beautiful beyond description. We witnessed a sea-fight between a whale and one of his many enemies, a killer. The sea was quite smooth. A short distance from the ship was seen a large whale, lashing the smooth sea into a perfect foam, and trying to disengage himself from his enemy. As they drew near the ship the struggle became more violent. The killer, which was about twenty feet long, held the whale by the lower jaw. The huge monster seemed to be in great agony, and spouted blood. Suddenly the whale threw himself out of the water, at full length, the killer hanging to his jaw; but all his flounderings and turning flukes were useless, as the killer still maintained his hold and was getting the advantage. He soon worried the whale to death. After the battle, the ship appeared to be floating in a sea of blood. During the last few days we saw many beautiful snow-white petrels either up in the freezing air or on the ice-floes.
January 22. Weather foggy. This morning we found bottom with eight hundred fathoms of line. The arming was covered with slate-colored mud. In the afternoon we took a second cast of the lead and found bottom at three hundred and twenty fathoms. The bottom same as before — slate-colored mud. The Peacock, while boxing off the ship from some ice under her bows, made a stern board which brought her in contact with an iceberg with such force as to crush her stern and larboard quarter boats, and carry away her bulwarks to the gangways. While getting out the ice anchor to heave the ship off, she gave a rebound which carried away her rudder and all the stanchions to the gangway. This second shock caused the ship to cant to starboard, when both jibs were given to her just in time to carry her clear of the iceberg. She had not moved more than a dozen lengths before a huge mass of ice fell from the iceberg in her wake. If this had happened twenty minutes before, it would have crushed the ship to atoms. As soon as we gained the open sea, Captain Hudson very wisely put the ship’s head for Sydney, where she arrived in a shattered and sinking condition. For several days the weather had been foggy.
