As to the maintenance of the balance of power between the established Maritime States of the Baltic, the tradition of British policy is no less clear.
When the Swedish power gave us some uneasiness there by threatening to crush Denmark, the honour of our country was kept up by retrieving the then inequality of the balance of power.
“The Commonwealth of England sent in a squadron to the Baltic, which brought on the treaty of Roskild (1658), afterwards confirmed at Copenhagen (1660).[127] The fire of straw kindled by the Danes in the times of King William III. was as speedily quenched by George Rooke in the treaty of Travendahl.” [128]
