 One group of five German torpedo boats, the 18th Half Flotilla, was on the outward leg into the Straits of Dover when they sighted "Laforey" and companions sailing from Dover to Dunkirk.The British ships did not spot the German torpedo boats, which continued on their way unhindered.Later that night, other German torpedo boats attacked British drifters, and when the old destroyer went to investigate, sank "Flirt".
