About nine at night, General Clinton silently drew off the van of the British army across the country, in order to seize a pass in the heights, about three miles east of Bedford, on the Jamaica road. In the morning, about two hours before day-break, within half a mile of the pass, his patrols fell in with and captured one of the American parties, which had been stationed on this road. Learning from his prisoners that the pass was unoccupied, General Clinton immediately seized it; and, on the appearance of day, the whole column passed the heights, and advanced into the level country between them and Brooklyn.[40] [Footnote 40: General Howe's letter.] Before Clinton had secured the passes on the road from Jamaica, General Grant advanced along the coast at the head of the left wing, with ten pieces of cannon. As his first object was to draw the attention of the Americans from their left, he moved slowly, skirmishing as he advanced with the light parties stationed on that road.[41] [Footnote 41: General Howe's letter.] This movement was soon communicated to General Putnam, who reinforced the parties which had been advanced in front; and, as General Grant continued to gain ground, still stronger detachments were employed in this service. About three in the morning, Brigadier General Lord Stirling was directed to meet the enemy, with the two nearest regiments, on the road leading from the Narrows. Major General Sullivan, who commanded all the troops without the lines, advanced at the head of a strong detachment on the road leading directly to Flatbush; while another detachment occupied the heights between that place and Bedford. About the break of day, Lord Stirling reached the summit of the hills, where he was joined by the troops which had been already engaged, and were retiring slowly before the enemy, who almost immediately appeared in sight. A warm cannonade was commenced on both sides, which continued for several hours; and some sharp, but not very close skirmishing took place between the infantry. Lord Stirling, being anxious only to defend the pass he guarded, could not descend in force from the heights; and General Grant did not wish to drive him from them until that part of the plan, which had been entrusted to Sir Henry Clinton, should be executed. [Sidenote: Battle of Brooklyn and evacuation of Long Island.] In the centre, General De Heister, soon after day-light, began to cannonade the troops under General Sullivan; but did not move from his ground at Flatbush, until the British right had approached the left and rear of the American line. In the mean time, in order the more effectually to draw their attention from the point where the grand attack was intended, the fleet was put in motion, and a heavy cannonade was commenced on the battery at Red Hook.
