You must before this time have heard of the capture of the late President Laurens, on his voyage hither; that the enemy affect to consider him a state prisoner, and have, accordingly, confined him to the Tower, _in arcta et salva custodia_. Their treatment of him has marked the barbarity of the nation from the throne to the footstool. Does this look like peace? They recovered a part of his papers, such as the plan of a treaty adjusted by Mr William Lee, with the Regency of this city in 1778, a letter from M. de Neufville upon the subject, one from our friend, the Commodore, one from Mr Stockton, and one from an amiable character of this country, whom I personally know, Baron Van der Cappellen. These were hurried over to Sir Joseph Yorke, and by him delivered to the Prince, who, it is said, in much wrath, laid them before the States of Holland, who transmitted copies of them to the Regency, accompanied with certain resolutions. The Regency have openly avowed the act. This has brought on the most extraordinary memorial of Sir Joseph Yorke to the States-General, which, perhaps, any foreign Minister ever made to an independent State; calling for their open disavowal of the conduct of the Regency; censuring them as a mad cabal, ever ready to sacrifice the public interests to private views, aiding the natural enemy (France) of both countries in destroying their mutual happiness; and it demands of the States-General also, an exemplary punishment of the Pensionary, Van Berckel, by name, and of all his _accomplices_, as disturbers of the public peace, and violaters of the laws of nations, that is, of the other members of the city Regency, for he acted officially in what he did, and by their order.
