four in the morning
He had destroyed one large Indian boat on his way down Channel . We exchanged good wishes . Like myself , he needed rest . I was up at four in the morning , however , and called all hands to overhaul the boat . She was somewhat up by the head , owing to the forward torpedoes having been used , so we trimmed her by opening the forward compensating tank , admitting as much water as the torpedoes had weighed . We also overhauled the starboard air-compressor and one of the periscope motors which had been jarred by the shock of the first explosion . We had hardly got ourselves shipshape when the morning dawned .
