DEAR HILL,--We are making great preparations for war in this State, and will have twenty thousand men in camp, besides those already in Missouri, in a very short time. There is a universal demand for the removal of Mr. Cameron, and I think after all, the sooner it is done the better. Mr. Lincoln certainly has no idea of the universal disposition of the whole people on this subject. I feel that Cameron wants to render the war unpopular by mismanagement, for they all know that if this war is successfully prosecuted that all the scoundrels cannot keep Mr. Lincoln from being re-elected President. Do tell Mr. Lincoln this thing, tell him also that he has the confidence of all parties, except the traitors.... I know Lincoln well enough to know that he will make no mistakes, if he will consult his own will and act up to it bravely and without hesitation. It is the best time in the world to be President, but he must be all President. Halfway measures will only now tend to our ruin and disgrace. I fear Trumbull is a rascal,--the idea of his being unprepared in the Senate to vote for the resolution approving the act of the President, has killed him off. I will bet you a bottle of wine that he sees the day he will want to exchange that little speech.... I am perhaps too impatient, and I am besides under some personal obligations to Mr. Cameron, but in this fight I care nothing about obligations of friendship in opposition to the welfare of the country. No one man nor any number of men can in my estimation be allowed for one moment to stand in the way of good government. Excuse me for all this and believe me in everything. I am, Your friend, W. A. HANNA. The city is full of soldiers and we are all marching left foot foremost. W. H. H. WILLARD'S HOTEL, 7 P. M. Aug. 30, 1861. DEAR SIR,--General Scott notified me that if I would make an arrangement with the President to receive the Fort Sumter Garrison at some definite time, he would be most happy to be present at the reception. My men are at leisure either to-morrow or Monday, or in fact any time during the next week. Will you have the kindness to arrange it and let me know the result? I will call at this hotel for your answer. Yours very truly, A. DOUBLEDAY. TO COL. WARD H. LAMON. FORT LAFAYETTE, Oct. 24, 1861.
