Early in the morning General Mifflin arrived in camp, with part of the troops which had been stationed at Fort Washington and King’s Bridge. He brought with him Shee’s prime Philadelphia regiment, and Magaw’s Pennsylvania regiment, both well disciplined and officered, and accustomed to act together. They were so much reduced in number, however, by sickness, that they did not amount in the whole, to more than eight hundred men. With Mifflin came also Colonel Glover’s Massachusetts regiment, composed chiefly of Marblehead fishermen and sailors, hardy, adroit, and weather-proof; trimly clad in blue jackets and trowsers. The detachment numbered, in the whole, about thirteen hundred men, all fresh and full of spirits. Every eye brightened as they marched briskly along the line with alert step and cheery aspect. They were posted at the left extremity of the intrenchments towards the Wallabout. There were skirmishes throughout the day, between the riflemen on the advanced posts and the British “irregulars,” which at times were quite severe; but no decided attack was attempted. The main body of the enemy kept within their tents until the latter part of the day; when they began to break ground at about five hundred yards distance from the works, as if preparing to carry them by regular approaches. On the 29th, there was a dense fog over the island, that wrapped every thing in mystery. In the course of the morning, General Mifflin, with Adjutant-general Reed, and Colonel Grayson of Virginia, one of Washington’s aides-de-camp, rode to the western outposts, in the neighborhood of Red Hook. While they were there, a light breeze lifted the fog from a part of the New York Bay, and revealed the British ships at their anchorage opposite Staten Island. There appeared to be an unusual bustle among them. Boats were passing to and from the admiral’s ship, as if seeking or carrying orders. Some movement was apparently in agitation. The idea occurred to the reconnoitring party that the fleet was preparing, should the wind hold and the fog clear away, to come up the bay at the turn of the tide, silence the feeble batteries at Red Hook and the city, and anchor in the East River. In that case the army on Long Island would be completely surrounded and entrapped.
