In truth, his present conduct made the case for the coercion of Denmark infinitely more urgent.
As to the reality of Napoleon's designs on Denmark, there can be no doubt.

After his return to France, he wrote from St.Cloud, directing Talleyrand to express his displeasure that Denmark had not fulfilled her _promises_: "Whatever my desire to treat Denmark well, I cannot hinder her suffering from having allowed the Baltic to be violated [by the English expedition to Stralsund]; and, if England refuses Russia's mediation, Denmark must choose either to make war against England, or against me."[164] Whence it is clear that Denmark had given Napoleon grounds for hoping that she would declare the Baltic a _mare clausum_.
The British Government had so far fathomed these designs as to see the urgency of the danger.

Accordingly it proposed to Denmark a secret defensive alliance, the chief terms of which were the handing over of the Danish fleet, to be kept as a "sacred pledge" by us till the peace, a subsidy of L100,000 paid to Denmark for that fleet, and the offer of armed assistance in case she should be attacked by France.
This offer of defensive alliance was repulsed, and the Danish Prince Royal determined to resist even the mighty armada which was now nearing his shores.
