Upon those men who are in sentiment opposed to the spread and nationalization of slavery, rests the task of preventing it. The Republican organization is the embodyment of that sentiment; though, as yet, it by no means embraces all the individuals holding that sentiment. The party is newly formed; and in forming, old party ties had to be broken, and the attractions of party pride and influential leaders were wholly wanting—In spite of old differences, prejudices, and animosities, its members were drawn together by a permanent common danger—They formed and manœuvered in the face of the disciplined enemy, and in the teeth of all his persistent misrepresentations— Of course, they fell far short of gathering in all their own—And yet, a year ago, they stood up, an army over thirteen hundred thousand strong—That army is, to-day, THE BEST HOPE OF THE NATION AND OF THE WORLD— Their work is before them; and FROM WHICH THEY MAY NOT GUILTLESSLY TURN AWAY. MAJOR JAMES M’HENRY TO GEN. GREENE [Part of letter of Major Jamel McHenry, member of the Continental Congress, military secretary to Washington, and afterwards Secretary of War, to General Greene. It is dated at Ambler’s Plantation, (opposite James Island, Va.), July 8, 1781. It is not signed, but is of great historical interest. He says:] On the 4th Instant, the Enemy evacuated Williamsburg, where some Stores fell into our Hands, and retreated to this Place, under the Cannon of their Shipping. Next Morning we advanced to Bird’s Tavern and a Part of the Army took Post at Narrell’s Mills about nine Miles from the British Camp.—The Sixth I detached an advanced Corps under Gen’l Wayne, with a View of reconnoitering the Enemy’s Situation. Their light Parties being drawn in, the Pickets which lay close to their Encampment were gallantly attacked by some Riflemen, whose Skill was employed to great Effect, Having ascertained that Lord Cornwallis had sent off his Baggage, under a proper Escort and posted his Army in an open Field fortified by the Shipping, I returned to the Detachment which I found more generally engaged. A Piece of Cannon had been attempted by the Van Guard under Major Galvan, whose conduct deserves high Applause. Upon this the whole British Army came out and advanced to the thin Wood occupied by Gen’l Wayne. His Corps chiefly composed of Pennsylvanians, and some light Infantry did not exceed eight hundred Men, with three Field Pieces. But notwithstanding their Numbers at Sight of the British Army, the Troops ran to the encounter, a short Skirmish ensued with a close Warm and well directed firing, but as the Enemy’s Right and Left, of Course greatly out flanked ours, I sent Gen’l Wayne Orders to retire Half a Mile to where Colonels Vose and Barber’s light Infantry Battalions had arrived by a rapid Move and where I ordered them to form, In this Position they remained ’till some Hours after Sunset, The Militia under Gen’l Lawson
