Washington, however, was mistaken as to the intentions of the enemy. Howe, instead of making a bold attack upon New York, resolved upon another course. He well knew that Long Island was filled with Tory sympathizers, and he thought that he might reach New York across Long Island, and be able to take with him many recruits gathered on his way from among the disloyal inhabitants. Within five days after the refusal of Washington to reply to his insulting letter, Howe prepared his fleet for action, and with it set sail for Gravesend Bay, where he landed on August 22. The fleet arrived early in the morning. General Sir William Howe led an army of 30,000 well-disciplined soldiers. The landing was effected without opposition. A part of the forces was under the command of Earls Cornwallis and Percy, Sir William Erskine, Count Duness, and Generals Grant, De Heister, and Knyphausen, and was composed of many Hessians who had been hired at a set price per head to do military service against the American rebels. Howe held possession of the southwestern part of the Island. His presence caused consternation among the patriots, who sought the American lines for protection, while those who were weak in the faith, or favored the cause of royalty, joined his standard. The small body of riflemen who had been stationed at Fort Hamilton could not prevent the landing of the invaders. They, however, destroyed the growing crops so that the enemy would derive no benefit from the cereals, and, having done this, sought safe quarters between Brooklyn and Flatbush. Meanwhile Howe was not idle. Establishing his headquarters at New Utrecht, he employed his men in reconnoitring. Skirmishers were sent out from time to time, who succeeded in capturing many straggling soldiers, and withal securing much plunder. General Sullivan, who was in command of the American forces, had but 5000 men. These lacked the ability to contend against the numbers opposed to them. Most of Sullivan's men were volunteers, unused to the hardships of camp life, and without experience in military tactics. Notwithstanding the disparity of numbers, Sullivan made diligent preparation to resist the onward progress of the enemy should they attempt to press forward to New York. Washington at this time was with the main body in New York, laboring earnestly to defend the lines of that city, and obstruct the progress of the enemy should they attempt to lay siege to the town.
