"After about a year of preparation, on 4 June, German Admiral Karl Rudolf Brommy left Bremerhaven with the steam frigate SMS Barbarossa (formerly RMS Britannia) and the smaller steam corvettes L\u00FCbeck (1844) and Hamburg (1841) in order to disperse the Danish ships which were guarding the mouth of Weser River. The Danish forces present that day were inferior and retreated, but Brommy managed to cut off the sailing corvette Valkyrien which under captain Andreas Polder sought refuge near the island of Heligoland which at the time belonged to United Kingdom. The British, while being neutral, had anyway made clear beforehand that a German Navy was not welcome and might be treated as pirates. Ships of both sides fired some shots, with no effect. When the German approached the island's three-mile zone, the British forces fired warning shots towards them, while allowing the Danish corvette to stay close. Brommy, not willing to draw the Royal Navy into the war, stayed at a distance while the Danish captain Polder was waiting for the arrival of reinforcements from the Danish main fleet. When the modern steamer Gejser, under kaptajnl\u00F8jtnant (captain lieutenant) J\u00F8rgen P. F. Wulff, came into sight, Brommy retreated, fearing further Danish reinforcements. The Danes followed the Germans to the mouth of the Elbe near Cuxhaven before resuming the blockade. It was the first and the last excursion of the small fleet under the black-red-gold Flag of Germany."@en . . . . . . . "2"^^ . . "Battle of Heligoland (1849)"@en . "Battle of Heligoland"@en .
