In the afternoon of 25 October, the pressure of the ice increased further. The main deck of the "Endurance" buckled upwards amidships and the beams sheared. As the ice moved against her stern, the aft part of the ship was lifted up and the damaged sternpost and the rudder were torn away. This angle caused all the water in the ship to run forward, collecting in the bow where it then began to freeze. The action of the ice in the stern and the excessive weight in the bow caused the ship to sink into the ice bow-first. Under its own pressure, the ice then broke over the forecastle and piled up onto the deck in the forward part of the ship, further weighing this end of the ship down. Through all of this, the pumping operations had continued, but by the end of the day Shackleton ordered this to stop and for the men to take to the ice.
