when the ice opened beneath them and closed again. It was a sad sight, but my chief concern just then was the safety of the rudder, which was being attacked viciously by the ice. We managed to pole away a large lump that had become jammed between the rudder and the stern-post, but I could see that damage had been done, though a close examination was not possible that day.
After the ship had come to a standstill in her new position very heavy pressure was set up. Some of the trenails were started and beams buckled slightly under the terrific stresses. But the Endurance had been built to withstand the attacks of the ice, and she lifted bravely as the floes drove beneath her. The effects of the pressure around us were awe-inspiring. Mighty blocks of ice, gripped between meeting floes, rose slowly till they jumped like cherry-stones squeezed between thumb and finger. The pressure of millions of tons of moving ice was crushing and smashing inexorably. If the ship was once gripped firmly her fate would be sealed.
The gale from the south-west blew all night and moderated during the afternoon of the 2nd to a stiff breeze. The pressure had almost ceased. Apparently the gale had driven the southern pack down upon us, causing congestion in our area; the pressure had stopped when the whole of the pack got into motion. The gale had given us some northing, but it had dealt the Endurance what might prove to be a severe blow. The rudder had been driven hard over to starboard and the blade partially torn away from the rudder-head. Heavy masses of ice were still jammed against the stern, and it was impossible to ascertain the extent of the damage at that time. I felt that it would be impossible in any case to effect repairs in the moving pack. The ship lay steady all night, and the sole sign of continuing pressure was an occasional slight rumbling shock. We rigged shelters and kennels for the dogs inboard.
The weather on August 3 was overcast and misty. We had nine hours of twilight, with good light at noon. There was no land in sight for ten miles from the mast-head. The pack as far as the eye could reach was in a condition of chaos, much rafted
