The action of 7 September 2009 took place when the German frigate Brandenburg, taking part of Operation Atalanta, chased and captured a pirate skiff south of Mukalla, in the Gulf of Aden, after suspicious activity was spotted on the small vessel by the frigate's helicopter during a reconnaissance mission. The boat was disabled by gunfire, and one suspect from her crew was killed. Four individuals were captured and weaponry confiscated and eventually destroyed.
