" As the vessel fell, the pressure rose. The hull creaked as if held inside the crushing fist of a giant, or the chomping maw of a giant fish. The most senior officers were unperturbed by the groaning of the metal, for they knew that the hull was thick and could withstand the terrible pressures of the deep, but the confidence of many others was shaken when bolts burst out of their holdings, striking walls, breaking the glass of gaslights, and even hitting members of the crew with a most violent force.
