The Battle of Gdansk Bay and the end of Operation Rurka.
A sailor patrolling the bridge of the destroyer ORP "Błyskawica", noticed. Several flags flew onto the mast of a nearby signal tower in the war port of Oksywie and fluttered in the light wind. The sailor looked at the flags once more and, in a calm voice, alerted the officer on duty. Within minutes, Commander Lieutenant Roman Stankiewicz , commander of the Polish Navy Destroyer Division, knew that the signal was announcing "Wykonać Peking" ( to carry out Peking ), one of a pair of orders he had been expecting for several days, but he secretly hoped they would never come. .
