Washington understood that the city's harbor would provide an excellent base for the British Navy during the campaign, so he established defenses there and waited for the British to attack . In July, the British under the command of General William Howe landed a few miles across the harbor from Manhattan on the sparsely - populated Staten Island, where they were slowly reinforced by ships in Lower New York Bay during the next month and a half, bringing their total force to 32,000 troops . Washington knew the difficulty in holding the city with the British fleet in control of the entrance to the harbor at the Narrows, and he moved the bulk of his forces to Manhattan, believing that it would be the first target . </P>
