General Benjamin Butler published his proclamation to the people of New Orleans. He had written it on the day his troops marched into the city, but the newspaper refused to publish it. (Butler solved this obstacle by having his soldiers take over the printing presses.) In the proclamation, Butler declared the city under martial law, disbanded the police force, forbade the publication of anti-Union papers, and decreed that the United States flag was to be “treated with the utmost deference and respect by all persons, under pain of severe punishment.”
At Yorktown, Virginia, Confederate commander Joseph Johnston had learned of the mass of siege artillery being arrayed against him and decided to evacuate, never mind that Jefferson Davis would be displeased. His preparations did not go unnoticed: both Union pickets and runaway slaves reported large numbers of wagons being rolled up to the Southern lines and loaded with equipment.
But on this date, Johnston ordered a bombardment of the Union lines. A canny general would have seen through the ruse: the Rebel guns were firing all up and down the lines, rather than concentrating on one position to prepare for an assault. But the Northern soldiers went to cover, and after dark, the Confederate evacuation began, undetected.
General McClellan had decided to put his trust in Allan Pinkerton rather than the reports of the "contrabands" or his own officers and men. Pinkerton claimed to have a spy in the Confederate commissary department who said that 119,000 rations per day were being distributed to Johnston's army. With 112,000 men on hand, McClellan came to the astonishing conclusion that he was outnumbered.
