1778 The celebrated Battle of Monmouth Courthouse, between Sir Henry Clinton and General Washington, took place on June 28, in which, what at first seemed a defeat, was turned, by the courage and promptness of General Washington, to a victory. The night after the battle, and while the American army lay on their arms with the expectation of renewing the conflict in the morning, the British general stole away and gained the heights of Middletown and the sure protection of the guns of the British fleet, which was lying in Sandy Hook Bay. General Washington considered it fruitless to pursue them any further, and marched his army to the Hudson and took a strong position,which covered the important passes of the Highlands on that river. One week after the battle, as recorded in Clinton’s own narrative of the war, “the King’s army descended from the High (lands) of Navesink, where I caused them to encamp, and embarking in transports (off Horse Shoe Cove) were conveyed to their respective stations on Staten, York, and Long Islands.”
