The Secretary of the Navy now detailed Captain John Rodgers to accompany Mr. Eads to the West, and purchase and fit out such steamers as should be found necessary for the service. Up to this time the Secretary of War had manifested the most supreme indifference in regard to the whole subject, but he now claimed entire jurisdiction in the matter, and this interference caused considerable vexation and delay. At length he issued an order to Mr. Eads and Captain Rodgers to proceed with their purchases. These gentlemen obtained the approval of General McClellan, in whose department the purchases were to be made, and began their operations.
Upon arriving at Cairo, they found one of the old snag-boat fleet, called the "Benton." Mr. Eads knew the boat well, as he had formerly owned her, and proposed to purchase and arm her, but Captain Rodgers did not approve the plan for converting her into a gunboat. Mr. Eads then proposed to purchase and arm several of the strong, swift boats used for the navigation of the Missouri River, and equip them at St. Louis, from which point there would always be water enough to get them below Cairo. Captain Rodgers disapproved this plan also, and went to Cincinnati, where he purchased and equipped the "Conestoga," "Tyler," and "Lexington," and started them down the river. They were not iron-clad, but were merely protected around the boilers with coal bunkers, and provided with bullet-proof oaken bulwarks. Mr. Eads had warned Captain Rodgers that he could not depend upon the Ohio to get his boats down to Cairo, and his predictions were realized. The boats were started from Cincinnati some time in July; they were detained on the bars of the Ohio for six or seven weeks, and did not reach Cairo until about the first of September; then the bottom of the "Tyler" was found to be so badly damaged by sand-bars that she had to be put on the marine railway for repairs.
In July, 1861, the War Department advertised for proposals to construct a number of iron-clad gunboats for service on the Mississippi River. On the 5th of August, when the bids were opened, it was found that Mr. Eads proposed to build these boats in a shorter time and upon more favorable terms than any one else. His offer was accepted, and on the 7th of August he signed a contract with Quartermaster-General Meigs to have ready for their crews and armaments, in sixty-five days, seven vessels, of about six hundred tons each, each to draw six feet of water, to carry thirteen heavy guns, to be plated with iron two and a half inches thick, and to steam nine miles per hour. "They were one hundred and seventy-five feet long, and fifty-one and a half feet wide; the hulls of wood; their sides placed out from the bottom of the boat to the water line at an angle of about thirty-five degrees, and from the water line the sides fell back at about the same angle, to form a slanting casemate, the gun-deck being but a foot above water. This 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."
By dint of such skill and energy as we have described, Mr. Eads, in the brief period of one hundred days, built and had ready for service a powerful iron-clad fleet of eight steamers, carrying one hundred and seven heavy guns, and having an aggregate capacity of five thousand tons. Such a work was one of the greatest in magnitude ever performed, and, as may be supposed, required a heavy capital to carry it to perfection. Mr. Eads soon exhausted his own means, and but for the assistance of friends, whose confidence in his integrity and capacity induced them to advance him large sums, would have been compelled to abandon the undertaking; for the Government, upon various pretexts, delayed for months the stipulated payments, and by its criminal negligence came near bringing the iron-clad fleet, so necessary to its success, to an untimely end. It was prompt enough, however, to commission the vessels as soon as they were ready. At the time they rendered such good service in the conquest of Forts Henry and Donelson, and compelled the fall of Island No. 10, they were still unpaid for, and the private property of Mr. Eads.
In the spring of 1862, Mr. Eads, in accordance with the desire of the Navy Department, submitted plans for light-draught armored vessels for service on the western rivers. He proposed an ingenious revolving turret to be used on these vessels, the performance of which he agreed to guarantee to the satisfaction of the Department; but the Government decided to use the Ericsson turret, which the recent encounter between the Monitor and Merrimac had proved to be a success. Mr. Eads was allowed, however, to modify the Ericsson turret considerably, in order to avoid making the draft of his steamers greater than was desired. He built the "Osage" and "Neosho," and when these vessels were launched, with all their weight on board, it was found that they were really lighter than the contract called for, a circumstance which permitted the thickness of their armor to be afterward increased half an inch without injuring their draught or speed.
In May, 1862, at the request of the Navy Department, Mr. Eads submitted plans for four iron-clads, iron hull propellers, to carry two turrets each of eight inches thickness, four eleven inch guns, and three-quarters inch deck armor, to steam nine nautical miles per hour, to carry three days' coal, and not to exceed a draught of six feet of water. His plans were accepted, and he constructed the "Winnebago," "Kickapoo," "Milwaukee," and "Chickasaw." Like the "Osage" and "Neosho," these vessels were found to be of lighter draught than had been agreed upon, and the Department ordered all four to have an extra plating of three-quarters inch armor, which was done. Three of the vessels were also reported, by the officers of the navy sent to examine them, to exceed the speed required by the contract, while the fourth was fully up to the standard.
