Philip Vian's command link to Cossack connects the Altmark incident with his later role in the Bismarck pursuit. He left a convoy in the care of a C-class cruiser and crossed the Atlantic with his destroyers before formal orders fully caught up with the move. A flying-boat report helped the force home on the cruiser already maintaining contact with Bismarck. Vian's Tribals and the Polish destroyer ORP Piorun then shadowed through the night and repeatedly closed for torpedo attacks.
