| 1941 | O21 (Dutch) | Late in the afternoon, off Milford Haven O21, O23 and their escort the Free French minesweeper FFS La Moqueuse encounter the British merchant Losada. As La Moqueuse was more than a mile behind both submarines the crew of the Losada think they were German U-boats and opened fire. To prevent being hit both submarines crash dive. The crew of La Moqueuse had not seen both submarines dive and was now also under the impression that a German U-boat was nearby and dropped three depth charges. O 21 was the target of the attack but sustains no damage. Both submarines surfaced shortly afterwards. |
