I do not think there is any danger of the Government's deliberately taking any step to precipitate hostilities upon my departure. On the contrary, if they let me go, it will be in the hope that the interruption of diplomatic relations will be all they have to fear from us. But they have so little control over their officers, that I think we must be prepared for acts of violence from subordinates, if they have the chance of performing them, in cases where no immediate danger is incurred. I shall suggest to the Governors and Naval Officers to take reasonable precautions against such acts. A filibustering expedition of the Irish on the frontiers of Canada, to damage the canals, or something of that sort, may also be on the cards.

It is generally believed that the Government will insist on an immediate advance of the Grand Army of the Potomac, in the hope of covering a surrender to England with (to use President Lincoln's phraseology) a 'sugar coating' of glory, in another quarter if possible.

You will perhaps be surprised to find Mr. Seward on the side of peace. He does not like the look of the spirit he has called up. Ten months of office have dispelled many of his illusions. I presume that he no longer believes in the existence of a Union Party in the South, in the return of the South to the arms of the North in case of a foreign war; in his power to frighten the nations of Europe by great words; in the ease with which the U.S. could crush rebellion with one hand and chastise Europe with the other; in the notion that the relations with England in particular are safe playthings to be used for the amusement of the American people. He sees himself in a very painful dilemma. But he knows his countrymen well enough to believe that if he can convince them that there is a real danger of war, they may forgive him for the humiliation of yielding to England, while it would be fatal to him to be the author of a disastrous foreign war. How he will act eventually, I cannot say. It will be hard for him to face present unpopularity, and if the President and Cabinet throw the whole burden on his shoulders, he may refuse to bear it. I hope that without embarrassing him with official threats, I have made him aware himself of the extreme danger of refusing our terms.
