The rate of leakage of seawater into the O'Brien continued to increase, and on 18 October it was necessary for O’Brien to head for the nearest anchorage. Large amounts of topside weights were jettisoned, and preparations were made for abandoning the ship, but her captain still thought that she could be taken intact to Pago Pago. However, at about 0600 on 19 October, her bottom suddenly split open considerably, and her forward and after hull portions began to work independently. At 0630 all hands except for a small salvage crew abandoned, but half an hour later the O'Brien was abandoned entirely. Just before 0800 she descended beneath the waves, and after steaming nearly 3,000 miles (5,500 km) since she had been torpedoed. All members of her crew were saved.
