Without consulting the Secretary of the Navy, Stanton had some fifty canal-boats loaded with stone and sent them to be sunk on Kettle Bottom Shoals, in the Potomac, to keep the "Merrimac" from reaching Washington. The canal-boats reached the Shoals, but the order to sink them was countermanded by cooler heads. They were left in a long row, tied up to the river bank. * * * * * The three doomed ships at Hampton Roads soon knew that at nine o'clock of that fateful night there had steamed in from the ocean a Union iron-clad. Her coming, however, brought scant comfort. "What is she like?" asked the first captain to hear the news. "Like? She's like a cheese-box on a raft." [Illustration: THE BATTLE OF THE "MONITOR" AND THE "MERRIMAC"] It was not a bad description. She was the "Monitor," an unknown boat of an unknown type that day, and on the morrow the most famous fighting craft that ever sailed the seas. She was born of the brain of a Swedish-American, Capt. John Ericsson, whose statue stands in Battery Park, the southern tip of the metropolis, looking down to the ocean he saved for freedom's cause. Lieut. A. L. Worden, commanding the "Monitor," was soon in consultation with the other commanders. They scarcely tried to disguise their belief that he had merely brought another predestined victim. His ship was tiny, compared with the "Merrimac." She was not built to ram, as was her terrible antagonist. Her guns were of a greater caliber, to be sure, than any wooden ship mounted, but there were but two of them and they could be brought to bear only by revolving the "Monitor's" turret,--a newfangled device in everyday use now, but then unknown and consequently despised. Men either fear or despise the unknown. They are usually wrong in doing either. The council of captains agreed upon a plan for the next day's fight. The plan was based upon the theory that the "Monitor" would be speedily sunk. Nevertheless, she was to face the foe first of all.
