Count: The government of his imperial and royal apostolic Majesty, and that of his Majesty the King of Prussia, have determined to grant a temporary national flag to the duchies of Holstein and Schleswig, till their definite construction, composed of three horizontal blue, white, and red stripes, with a yellow square on the blue stripe, near the staff.
I am charged on this account in connexion with my Prussian colleague, to invite the government of her Britannic Majesty to recognize this flag, and to give the orders necessary for its recognition in all the ports dependent on the Crown of England, and by all the British naval authorities.
The imperial government is pleased to hope that until the conclusion of new treaties of navigation with the government, to be constituted in the duchies, vessels sailing under the temporary national flag may enjoy the same rights and immunities granted to vessels of Holstein, Schleswig, and Lunenburg, before their separation from Denmark, according to treaties of commerce and navigation existing with that kingdom.
In asking your excellency to communicate to me, at your leisure, the result of this request, I remain, &c., &c., &c.
