Captain Glenn , tired out , announced that he was going below to get `` forty winks . '' Jack took the bridge . `` Call me if anything happens , '' were the commander 's last words as he went below . Along toward four o'clock a man emerged from below and fought his way toward the bridge . `` Leak in the main compartment aft , sir , '' he reported to Jack . Jack ordered Frank below to learn the extent of the damage . `` Pretty bad this time , Jack , '' said Frank , reporting a few minutes later .
