Since Radbod's dominions extended from Duerstede to Heligoland his power must have been by no means inconsiderable.
Among the best known is the patriotic Deutschland, Deutschland fiber Alles, composed in 1841 on the island of Heligoland, where a monument was erected in 1891 to his memory (subsequently destroyed).
Thus perjured and disgraced the young king embarked for Scotland on the 2nd of June; on the 11th when off Heligoland he signed the treaty, and on the 23rd, on his arrival at Speymouth, before landing, he swore to both the covenants.
The acquisition of Heligoland enabled a new naval station to be established off the mouth of the Elbe; the completion of the canal from Kid to the mouth of the Elbe, by enabling ships of war to pass from the Baltic to the North Sea greatly increased the strategic strength of the fleet.
It appeared a small compensation that Great Britain surrendered to Germany the island of Heligoland, which she had taken from the Danes in the Napoleonic wars.
