On 21 November an Ottoman convoy was attacked by the four Bulgarian torpedo boats Drazki (Bold), Letyashti (Flying), Smeli (Brave) and Strogi (Strict). The attack was led by Letyashti, whose torpedoes missed, as did those of Smeli and Strogi, Smeli being damaged by a 150 mm round with one of her crewmen wounded. Drazki however got within 100 meters from the Ottoman cruiser and her torpedoes struck the cruiser's starboard side, causing a 10 square meter hole.
