Had morning Watch. Hands called at 4.30. Closed up at Action Stations at 5.30. All very fed up when secure sounded at 6 o’clock. as quite thought there was something doing, especially as we heard shots on port side, which turned out to be from “Cordelia” who sunk trawler with all hands, carrying guns & winless. Carried out usual sea routine at 6.45. Pipe down in afternoon. Got head down.
