Destroyers HMS Doon, Test, Waveney and HMS Moy were on patrol when Doon saw three large vessels approaching at 07:45, which opened fire shortly after. The only weapons the destroyers carried capable of damaging large vessels were torpedoes; as the ships were out of torpedo range the destroyers turned away except for Doon, which closed to 5,000 yd (2.8 mi; 4.6 km), fired one torpedo which missed and also turned away.[9]
