Mr. Haldeman to Mr. Seward.

No. 50.]

Sir:* * * * * * *

The conference has dissolved; the German-Danish war is renewed. This was anticipated for some time, and has taken none by surprise.

The renunciation of the Emperor of Russia of all his rights as head of the house of Holstein Gottorp, in favor of the Grand Duke of Oldenburg, seems to be in favor and in support of the policy of Prussia, that desires to set up a rival for her own purposes to the claim of the Duke of Augustenbourg to Schleswig-Holstein; and while the Diet of the Germanic confederation are discussing and deciding in solemn deliberations the merits of the contending claimants, (requiring years, according to German precedents, to decide correctly so grave and weighty a question,) Prussia, in possession of that she most covets, will Prussianise, incorporate, and absorb the duchies within herself, make a reality of her brightest dream by the creation of a German fleet, and then hold and retain the duchies by the right of conquest and possession. This seems the most rational explanation of the conduct and renewal of the war on the part of Prussia.

Sweden, though far from an indifferent spectator to the struggle, is well aware that alone she can give no efficient aid to Denmark—that her assistance would do no good; but, on the contrary, excite German nationality to fever-heat. But Sweden has always been ready and prepared to join and assist England at a moment’s notice in aught that England may propose to do for Denmark.

A short time will decide if the war will extend beyond its present and former limits. Will the German powers rest content with the three duchies, or will they attack the island of Laland, Funen, and Zeland? If so, will England send a fleet to protect them? This is now the most important question. Its solution will remove much uncertainty and speculation now existing.

I remain, your obedient servant,

J. S. HALDEMAN.

Hon. William H. Seward, Secretary of State, Washington, U. S. of A.
