Z. CHANDLER. [REPLY.] WASHINGTON, April 29, 1861. _Hon. Z. Chandler._ DEAR SIR: ... It would give me great pleasure to gratify your wishes, but this can only be done in one way. The President has determined to accept no more for three months' service, but to add to the regular army twenty-five more regiments whose members shall agree to serve two years unless sooner discharged. This will enable the Department to accept another regiment from your State. Truly yours, SIMON CAMERON, _Secretary of War_. To this suggestion the response was prompt, and the enlistment of men and formation of companies for three years' service went briskly on, Michigan sending only one three-months' regiment to the field. Mr. Chandler was active in stimulating and organizing the war movements at home, both by untiring personal labor and by liberal subscriptions of money, until the first regiments were ready for marching orders. He was one of the speakers at an imposing Union meeting held in Detroit on April 25, with Lewis Cass in the chair, and he there said: "A greater contest than the Revolutionary war is now about to take place. It is to be tested whether a republican government can stand or not. The eyes of all Europe are upon us, and we will convince them that ours is the strongest government on earth." He also made an earnest, and in the end successful, effort to procure from the War Department such orders as should obtain for the Michigan men an opportunity for prompt service against the enemy. It was originally intended to send the regiments from his State to Cairo, but his influence accomplished a change in this plan and they were directed to report to Washington for immediate duty. In May Mr. Chandler went to the capital to aid in preparing for their reception and to urge upon the authorities, who were then declining the profuse offers of troops, the importance of accepting all the regiments tendered by his own and other States and of promptly attacking the constantly growing rebellion by invading its territory and interfering with the organization of its armies. On the 17th of May, 1861, the First Regiment of Michigan Volunteers arrived in Washington, Col. O. B. Willcox commanding. They were met at the depot by Senator Chandler and escorted to quarters he had aided in securing for them in a business block on Pennsylvania Avenue. Mr. Chandler was active in providing for their comfort, purchased supplies for them out of his own private purse, was present at their parade when they were formally mustered into the service of the United States by Adjutant-General Thomas, and asked the Secretary of War to send them at once to the front for active duty. His request was complied with and this regiment was prominent in the first important military movement of the war.
