the next move of the gigantic forces arrayed against us. The 23rd brought a strong north-westerly wind, and the movement of the floes and pressure-ridges became more formidable. Then on Sunday, October 23, there came what for the Endurance was the beginning of the end. The position was lat. 69° 11′ S., long. 51° 5′ W. We had now twenty-two and a half hours of daylight, and throughout the day we watched the threatening advance of the floes. At 6.45 p.m. the ship sustained heavy pressure in a dangerous position. The attack of the ice is illustrated roughly in the appended diagram. The shaded portions represent the pool,
covered with new ice that afforded no support to the ship, and the arrows indicate the direction of the pressure exercised by the thick floes and pressure-ridges. The onslaught was all but irresistible. The Endurance groaned and quivered as her starboard quarter was forced against the floe, twisting the stern-post and starting the heads and ends of planking. The ice had lateral as well as forward movement, and the ship was twisted and actually bent by the stresses. She began to leak dangerously at once.
I had the pumps rigged, got up steam, and started the bilge-pumps at 8 p.m. The pressure by that time had relaxed. The ship was making water rapidly aft, and the carpenter set to work to make a coffer-dam astern of the engines. All hands worked, watch and watch, throughout the night, pumping ship and helping the carpenter. By morning the leak was being kept in check.
