slanting casemate extended across the hull, near the bow and stern, forming a quadrilateral gun-deck.  Three nine or ten-inch guns were placed in the bow, four similar ones on each side, and two smaller ones astern.  The casemate inclosed the wheel, which was placed in a recess at the stern of the vessel.  The plating was two and a half inches thick, thirteen inches wide, and was rabbeted on the edges to make a more perfect joint.”

In undertaking to complete these vessels in sixty-five days, Mr. Eads had assumed a heavy responsibility.  The manufacturing interests of the West were sadly crippled by the sudden commencement of hostilities, and doubt and distrust prevailed every-where.  The worst feature of all was, that skilled workmen were either enlisting in the army or seeking employment in States more remote from the scene of war.  Every thing needed for the gunboats was to be made.  Even the timber for their hulls was still standing in the forest, and the huge machinery which was to roll out and harden their iron plates had yet to be constructed.  No single city, no two cities, however great in resources, could possibly supply every thing needed within the stipulated time, and it was necessary to employ help wherever it could be obtained.

The very day the contract was signed, the telegraph was kept busy sending instructions all over the West for the commencement of the various parts of the work.  The saw-mills in Kentucky, Tennessee, Illinois, Indiana, Ohio, Minnesota, and Missouri were set to getting out the timber, which was hurried to St. Louis by railroad and steamboat as fast as it was ready.  There were twenty-one steam engines and thirty-five boilers to be made, and the machine-shops in St. Louis, Cincinnati, and Pittsburgh were put to work upon them.  The huge rolling-mills of Cincinnati and Portsmouth, Ohio, Newport, Kentucky, and St. Louis were engaged in making the iron plates, and employed for this purpose no less than four thousand men.  Night and day, Sundays included, the work went on with an almost superhuman swiftness.  Mr. Eads paid the workmen on the hulls large sums from his own pocket, in addition to their wages, to induce them to continue steadily at their work.

On the 12th of October, 1861, just forty-five days from the time of laying her keel, the first iron-clad, belonging to the United States, was launched, with her engines and boilers on board.  Rear Admiral Foote (then a flag officer), appointed to command the Mississippi squadron, named her the “St. Louis,” but upon being transferred to the Navy Department her name was changed to the “Baron de Kalb.”  She was followed by the other vessels in rapid succession, all being completed within the stipulated time.

In September, 1861, General Fremont ordered the purchase of the snag boat “Benton,” which had been proposed by Mr. Eads and rejected by Captain Rodgers, and sent her to Mr. Eads to be armored and equipped as a gunboat.  Work was at once begun on her, and pushed forward with the same energy that had been displayed in the construction of the other iron-clads.  Her performances during the war fully sustained the high esteem in which she was held by the officers of the navy.  Admirals Foote and Davis pronounced her the “best iron-clad in the world.”
