The serious consideration of congress was given to the overture, and on the 17th of June, their answer was returned. In substance it was, that they would be ready to enter upon the consideration of peace and commerce, not inconsistent with treaties already subsisting, when the king of Great Britain should demonstrate a sincere disposition for that purpose; of which no other proof could be admitted but that of an explicit acknowledgment of the independence of the United States, or the withdrawal of his fleets and armies. Thus terminated the negotiation. America, steady to her purpose, would not listen to any proposal which did not involve the recognition of her independence. Great Britain was yet too proud to accede to such terms, and consequently, the idea of accommodation was abandoned, and the most vigorous measures were adopted to wage war against her ancient ally and her disobedient child, whose fortunes had now become linked together. It may be added in this place, that, subsequent to the failure of the commissioners in effecting the object of their mission, commenced a system of intrigue with several distinguished persons, and especially with members of congress, to whom one at least addressed confidential letters, with the hope of winning them to the royal cause. Some of these letters and propositions at length were made public. General Reed, a member of congress, stated that a proposition had been made to him by Johnstone, through a _lady_, that if he would promote the rëunion of the two countries, he should have any office in the colonies which he might name. His reply was worthy of a Christian and a patriot: "_I am not worth purchasing; but such as I am, the king of Great Britain is not rich enough to do it_." 4. BATTLE OF MONMOUTH. During the winter of 1777-8, the British army had occupied Philadelphia; the winter-quarters of the American army were at Valley Forge. On the opening of the spring, in consequence of the alliance of France and America, orders were issued to the British general to evacuate Philadelphia, and concentrate the royal force in the city and harbor of New York. In pursuance of this resolution, the royal army, now under command of Sir Henry Clinton--General Howe having returned to England--left Philadelphia, and on the 18th of June, passed the Delaware into New Jersey. Washington immediately quitted his camp, and hung upon the British army, watching a favorable opportunity to offer battle. On the 27th, the British army encamped on some high grounds in the neighborhood of Freehold court-house, in the county of Monmouth. On the morning of the 28th, General Lee was ordered to take command of five thousand men, and commence the attack. At first, he declined the honor; but judging, on reflection, that such a procedure would redound to his discredit, he now sought the command at the hands of Lafayette, to whom, on his declining it, it had been tendered.
