One day, while nervously awaiting the arrival of reinforcements, Lincoln thought he heard cannonfire in the distance, signaling what he believed was a Confederate attack. Nonplussed by his aides’ insistence that they heard nothing, he walked over to the Arsenal, which he found unguarded, much to his surprise and dismay. All was quite still both there and along his route back to the White House. As he returned, he asked passersby if they had heard cannonading earlier. When they said that they had not, he assumed his imagination was playing tricks on him.
