General _Howe_ had at length ripened his plan for cutting off gen. _Washington_’s communication with the eastern states, and enclosing him on all sides in his fastnesses on the north end of New-York island; which ought to have been executed a month back, by a bold and unexpected removal of the troops from Long-Island in the first instance, to Rochelle or the neighborhood. The greater part of the army, being embarked in flat boats and other small craft, passed through Hell-gate, a passage terrible in name, but no way dangerous at the proper time of tide; entered the Sound [Oct 12.] and landed early in the morning, on _Frog_’s-_Neck_, in Westchester county, belonging to New-York, upon the side of Connecticut. Gen. Washington’s army, fit for duty, present and on command at different posts, militia included, was about 19,000. Officers and men were in expectation of active service. The former were out frequently in reconnoitering parties; the latter were looking out for the arrival of gen. Lee, on his way to the camp. The Americans had no intention of quitting their ground upon the island and the neighborhood of Kingsbridge; but a number of regiments were sent forward to counteract the operations of the enemy. When the royal army was landed, the general’s found they could not get upon the continent, by reason of the causeway’s being broken down, and of works being erected to oppose them. Six days were spent here to little purpose, while a dozen other places were open, where the troops might have landed with scarce any or no opposition or difficulty attending them. On the last of these days the second division of foreign mercenaries arrived at New-York. The fleet consisted of seventy-two sail, having on board 4000 Hessians, 1000 Waldeckers, two companies of chasseurs or riflemen, 200 English recruits, and 2000 baggage horses. The horse transports were heavy sailing Dutchmen. They left St. Helen’s the 28th of June, were obliged to put into Plymouth the 7th of July, and sailed from thence the 19th.
