"To the deceased, who was conservative in his views and actions, belongs the credit of first enunciating the 'contraband' idea as subsequently applied in the practical treatment of the slaves of rebels, Early in the spring of 1861, Flag-Officer Pendergrast, in command of the frigate 'Cumberland,' then the vessel blockading the Roads, restored to their owners certain slaves that had escaped from Norfolk. Shortly after, the Flag-Officer, Gen. Butler, Capt. Talmadge, and the writer chanced to meet in the ramparts of the fortress, when Capt. T. took occasion, warmly, but respectfully, to dissent from the policy of the act, and proceeded to advance some arguments in support of his views. Turning to Gen. Butler, who had just assumed command of this department, he said: 'General, it is a question you will have to decide, and that, too, very soon; for in less than twenty-four hours deserting slaves will commence swarming to your lines. The rebels are employing their slaves in thousands in constructing batteries all around us. And, in my judgment, in view of this fact, not only slaves who take refuge within our lines are contrabands, but I hold it as much our duty to seize and capture those employed, or intended to be employed, in constructing batteries, as it is to destroy the arsenals or any other war-making element of the rebels, or to capture and destroy the batteries themselves.' Within two days after this conversation, Gen. Butler has the question practically presented to him, as predicted, and he solved it by applying the views advanced by the deceased."[82] The conservative policy of Congress, the cringing attitude of the Government at Washington, the reverses on the Potomac, the disaster of Bull Run, the apologetic tone of the Northern press, the expulsion of slaves from the Union lines, and the conduct of "Copperheads" in the North--who crawled upon their stomachs, snapping and biting at the heels of Union men and Union measures,--bred a spirit of unrest and mob violence. It was not enough that the service of free Negroes was declined; they were now hunted out and persecuted by mobs and other agents of the disloyal element at the North. Like a man sick unto death the Government insisted that it only had a slight cold, and that it would be better soon. The President was no better informed as to the nature of the war than other conservative Republicans. On the 19th of August, 1862, Horace Greeley addressed an open letter to the President, known as "The Prayer of Twenty Millions," of which the following are specimen passages:
