Again the next morning came and again there came the rebel ram. Decked out in flags as if for a festival, proudly certain of victory, the "Merrimac" steamed down Hampton Roads. The cheese-box on a raft steamed out to meet her. It was David confronting Goliath. Goliath had fourteen guns and David had two. The iron-clads came nearer and the most famous sea-duel ever fought began. Tom saw it all from the bridge of the "Minnesota." Both vessels fired and fired again, without result. Their armor defied even the big guns they carried. Then the "Merrimac" tried to bring her deadly ram into play. The "Monitor" dodged into shoal water, hoping her foe would follow her and run aground. The "Merrimac" did not fall into the trap. On the contrary, she left her adversary and made a headlong course for the helpless "Minnesota." On board the latter, drums beat to quarters, shrill whistles gave orders, and the great ship moved forward to what seemed certain destruction. But the "Monitor" slipped away from the shoals and made after the "Merrimac," firing her guns as rapidly as her creaking turret could turn. The "Merrimac" faced about, bound this time to make short work of this wretched little gnat that was seeking to sting her. This time the two came to close grips. Each tried to ram the other down. Each struck the other, but struck a glancing blow. They lay almost alongside and pounded each other with their giant guns. A missile from the "Monitor" came through a porthole of the "Merrimac," breaking a cannon and dealing death and destruction within her iron sides. She turned and ran for safety to the shelter of the Confederate batteries at Norfolk. The "Monitor" lay almost unharmed upon the gentle waves of Hampton Roads, the ungainly master of the seas. The "Merrimac" never dared again to try conclusions with her stout little rival. She stayed at her moorings until she was blown up there just before the Union forces captured Norfolk. The Union blockade was never broken. The "Monitor" survived the fight only to founder later in "the graveyard of ships," off Cape Hatteras. The wires had told the story of the famous fight before Tom reached Washington, but he was the first eye-witness of it to reach there and he had to tell the tale many and many a time. His first auditors were Lincoln and Secretary Welles. The dispatch boat that carried him back put him on board the President's boat, south of Kettle Bottom Shoals, on the Potomac, in obedience to orders signaled to it. When he had finished his story, there was silence for a moment. The boy saw Lincoln's lips move, perhaps in prayer, perhaps in thanksgiving. Then the grave face relaxed and the pathetic eyes twinkled with humor. The President laid his hand upon the Secretary's arm and pointed to a long line of stone-laden canal-boats that bordered the bank. "There's Stanton's navy," said Lincoln. CHAPTER IV
