In order to understand the true import of the news which arrived at the Foreign Office from various quarters on July 16–23, 1807, it is necessary briefly to review the general situation. The coalition against France formed by the Powers, Russia, Prussia, Great Britain, and Sweden, entered upon a new phase when Russia and Prussia signed the Convention of Bartenstein, April 26, 1807. Its aims were to strengthen the alliance between those two Powers, and to bring Great Britain and Sweden into more active co-operation in the Continental War, to put an end to the vacillation of Austria and bring her into the field once more, and, lastly, if possible to secure the adhesion of Denmark. This last clause was worded as follows:—The allies proposed ‘à se concerter avec l'Autriche, l'Angleterre, et la Suéde pour faire accéder le Danemark à cette convention.’ These words clearly left it open to the allies to use force in bringing Denmark to their side. It should further be noticed, as bearing on one part of our inquiry, that the Courts of Russia and Prussia bound themselves never to dissociate their fortunes but to act in the closest accord. The terms of the Convention of Bartenstein were forwarded to Downing Street by Mr. George Jackson, British chargé d'affaires at the Court of Prussia, and received a hearty welcome from Canning.
