and deployment to Hampton Roads was driven by fears of what the Confederate ironclad, now renamed Virginia, would be capable of doing, not only to Union ships but to cities along the coast and riverfronts. Northern newspapers published daily accounts of the Confederates' progress in converting the Merrimack to an ironclad; this prompted the Union Navy to complete and deploy Monitor as soon as possible. Word of Merrimacks reconstruction and conversion was confirmed in the North in late February 1862 when Mary Louvestre of Norfolk, a freed slave who worked as a housekeeper for one of the Confederate engineers working on Merrimack,<ref>[[#cia|CIA: Historical Document: Black Dispatches]].</ref> made her way through Confederate lines with news that the Confederates were building an ironclad warship. Concealed in her dress was a message from a Union sympathizer who worked in the Navy Yard warning that the former Merrimack, renamed Virginia by the Confederates, was nearing completion. Upon her arrival in Washington Louvestre managed to meet with Secretary of the Navy Gideon Welles and informed him that the Confederates were nearing the completion of their ironclad, which surprised Welles. Convinced by the papers Louvestre was carrying, he had production of Monitor sped up. Welles later recorded in his memoirs that "Mrs. Louvestre encountered no small risk in bringing this information ...".Tomblin, 2009, p. 161 Approval After the United States received word of the construction of Virginia, Congress appropriated $1.5 million on 3 August 1861 to build one or more armored steamships. It also ordered the creation of a board to inquire into the various designs proposed for armored ships. The Union Navy advertised for proposals for "iron-clad steam vessels of war" on 7 August and Welles appointed three senior officers as the Ironclad Board the following day. Their task was to "examine plans for the completion of iron-clad vessels" and consider its costs. Ericsson originally made no submission to the board, but became involved when Cornelius Bushnell, the sponsor of the proposal that became the armored sloop , needed to have his design reviewed by a naval constructor. The board required a guarantee from Bushnell that his ship would float despite the weight of its armor and Cornelius H. DeLamater of New York City recommended that Bushnell consult with his friend Ericsson. The two first met on 9 September and again on the following day, after Ericsson had time to evaluate Galenas design. During this
