It was determined on, at war-councils and in committees of conference, in 1775, that negroes should be rejected from the enlistments; and yet General Washington found, in that same year, that the negroes, if not employed in the American army, would become formidable foes when enlisted by the enemy. We may judge, from a note given by Mr. Moore, that Washington had at least a higher opinion than his _confreres_ of the power of the black. His apprehensions, we are told, were grounded somewhat on the operations of Lord Dunmore, whose proclamation had been issued declaring 'all indented servants, negroes or others, (appertaining to rebels,) free,' and calling on them to join his Majesty's troops. It was the opinion of the commander-in-chief, that if Dunmore was not crushed before spring, he would become the most formidable enemy America had; 'his strength will increase as a snow-ball by rolling, and faster, if some expedient can not be hit upon to convince the slaves and servants of the impotency of his designs.' Consequently, in general orders, December 30th, he says: 'As the General is informed that numbers of free negroes are desirous of enlisting, he gives leave to the recruiting-officers to entertain them, and promises to lay the matter before the Congress, who, he doubts not, will approve of it.' Washington communicated his action to Congress, adding: 'If this is disapproved of by Congress, I will put a stop to it.' His letter was referred to a committee of three, (Mr. Wythe, Mr. Adams, and Mr. Wilson,) on the fifteenth of January, 1776, and upon their report on the following day the Congress determined: 'That the free negroes who have served faithfully in the army at Cambridge may be reenlisted therein, but no others.' That Washington, at a later period at least, warmly approved of the employment of blacks as soldiers, appears from his remarks to Colonel Laurens, subsequent to his failure to carry out what even as an effort forms one of the most remarkable episodes of the Revolution, full details of which are given in Mr. Moore's pamphlet. On March 14th, 1779, Alexander Hamilton wrote to John Jay, then President of Congress, warmly commending a plan of Colonel Laurens, the object of which was to raise three or four battalions of negroes in South-Carolina. We regret that our limits render it impossible to give the whole of this remarkable document, which is as applicable to the present day as it was to its own.
