During this time, De Heister had commenced his part of the plan by opening a cannonade from his camp at Flatbush, upon the redoubt, at the pass of the wooded hills, where Hand and his riflemen were stationed. On hearing this, General Sullivan, who was within the lines, rode forth to Colonel Hand’s post to reconnoitre. De Heister, however, according to the plan of operations, did not advance from Flatbush, but kept up a brisk fire from his artillery on the redoubt in front of the pass, which replied as briskly. At the same time, a cannonade from a British ship upon the battery at Red Hook, contributed to distract the attention of the Americans. In the mean time terror reigned in New York. The volleying of musketry and the booming of cannon at early dawn, had told of the fighting that had commenced. As the morning advanced, and platoon firing and the occasional discharge of a field-piece were heard in different directions, the terror increased. Washington was still in doubt whether this was but a part of a general attack, in which the city was to be included. Five ships of the line were endeavoring to beat up the bay. Were they to cannonade the city, or to land troops above it? Fortunately, a strong head-wind baffled their efforts; but one vessel of inferior force got up far enough to open the fire already mentioned upon the fort at Red Hook. Seeing no likelihood of an immediate attack upon the city, Washington hastened over to Brooklyn in his barge, and galloped up to the works. He arrived there in time to witness the catastrophe for which all the movements of the enemy had been concerted.
