three were aground. The United States Navy's greatest defeat (and would remain so until World War II) caused panic in Washington. As Lincoln's Cabinet met to discuss the disaster, the frightened Secretary of War Edwin Stanton told the others that Virginia might attack East coast cities, and even shell the White House before the meeting ended. Welles assured his colleagues that they were safe as the ship could not traverse the Potomac River. He added that the Union also had an ironclad, and that it was heading to meet Virginia. March 9: Monitor engages Virginia Both sides used the respite to prepare for the next day. Virginia put her wounded ashore and underwent temporary repairs. Captain Buchanan was among the wounded, so command on the second day fell to his executive officer, Lieutenant Catesby ap Roger Jones. Jones proved to be no less aggressive than the man he replaced.

Soon, however, it was apparent that he had no choice but to fight her. The first shot of the engagement was fired at Monitor by Virginia. The shot flew past Monitor and struck Minnesota, which answered with a broadside; this began what would be a lengthy engagement. "Again, all hands were called to quarters, and when she approached within a mile of us I
