The evening preceding the action, General Washington, with a number of general officers, went down to view the motions of the enemy, who were encamped at Flatbush. The enemy appeared to be striking their tents, and preparing for a march; whereupon it was ordered that 2400 men should be posted as guards, in the following manner, viz: 800 on the road that leads out of the Jamaica road by way of Yellow Hook to Flatbush; these men were posted in a woods, at four miles distant from our lines, to oppose the enemy if they attempted that road, and to annoy them on their march: 800 more were posted in a woods upon the Middle road, which leads out of the Jamaica road to Flatbush, about a mile and a half from the lines; these were posted at about half a mile distant from Flatbush, and near a mile from the parting of the road, where an _abatis_ was formed across the road, and a breastwork thrown up and defended by two pieces of cannon: 800 more were posted at the Bedford road, which leads out of the Jamaica road, at about three miles distant from our lines; this party was ordered to guard the Bedford road, and to patrol the road leading through the New Lots in the east of the Bedford road, from which it parts at the Halfway House, about six miles from the lines, and leads from it to Flatbush. Five officers were also sent out on horseback to patrol the last-mentioned road and that leading to Jamaica. At 10 o'clock at night about 5000 of the enemy marched by way of the New Lots, and arrived, near 2 in the morning, at Halfway House, without being discovered; they took post in a field, and waited for daylight. The five officers sent to patrol fell into their hands, and were all made prisoners. About 3 in the morning a party of the enemy advanced into the Western road, leading by Yellow Hook, and attacked our guards; the guards returned their fire, threw them into confusion, caused the whole to halt, and took one prisoner, who informed us that he belonged to the regiment which attacked our guards, and was by their fire thrown into confusion and forced to retreat, and that there were two brigades, of four regiments each, on their march in that road, commanded by Brigadier-General Grant. At daylight Lord Stirling was ordered with two battalions, into that road, to oppose the enemy. He took post on an eminence in front of the enemy whereupon a smart fight ensued, which lasted near an hour, and then abated. Two field-pieces were sent to Lord Stirling, which soon began to play upon the enemy, who returned the fire from four field-pieces. The two parties stood opposed to each other for near five hours, without either seeming to have the advantage, keeping up a continual fire from their field-pieces, and musketry, with some intervals.--About 8 o'clock General Sullivan sent (went?) down the flat (bush) middle (road) and inquired of the guards whether they discovered any movements of the enemy in either of the roads. He was informed that the whole body of
