The impression made upon my mind by the attack on Fort Sumter is expressed in a letter I wrote from Washington to my brother, General Sherman, as he was then called, at midnight of the 12th of April: "Washington, April 12, 1861. "Dear Brother:--I was unexpectedly called here soon after receiving your letter of the 8th, and at midnight write you. The military excitement here is intense. Since my arrival I have seen several officers, many citizens, and all the heads of departments except Blair. There is a fixed determination now to preserve the Union and enforce the laws at all hazards. Civil war is actually upon us, and, strange to say, it brings a feeling of relief; the suspense is over. I have spent much of the day in talking about you. There is an earnest desire that you go into the war department, but I said this was impossible. Chase is especially desirous that you accept, saying that you would be virtually Secretary of War, and could easily step into any military position that offers. "It is well for you seriously to consider your conclusion, although my opinion is that you ought not to accept. You ought to hold yourself in reserve.

"Let me now record a prediction. Whatever you may think of the signs of the times, the government will rise from this strife greater, stronger, and more prosperous than ever. It will display energy and military power. The men who have confidence in it, and do their full duty by it, may reap whatever there is of honor and profit in public life, while those who look on merely as spectators in the storm will fail to discharge the highest duty of a citizen, and suffer accordingly in public estimation. . . . "I write this in great hurry, with numbers around me, and exciting and important intelligence constantly repeated, even at this hour; but I am none the less in earnest. I hope to hear that you are on the high road to the 'General' within thirty days. "Affectionately your brother, "John Sherman." Two days later I wrote him:
