Washington concentrated his army at White Plains, completed two lines of works, with his right on the river Bronx, and awaited the advance of the British. Howe had moved from New Rochelle to Scarsdale, and on the morning of the 28th marched against the Americans. A mile or more from White Plains, on the main road to New York, he fell in with General Spencer's advance parties under Colonels Silliman, Douglas,[212] and Chester, who offered resistance and lost some men, but they were driven back by superior numbers. On the left of the American position, across the Bronx, rose Chatterton's Hill, which offered a good site for the better defence of that flank. Colonel Putnam had just arrived on the hill to throw up works when the enemy made their appearance below.[213] According to Haslet, the Delawares were the first troops to report on this hill, where they took post with one of General Lincoln's Massachusetts militia regiments, under Colonel Brooks, on their right. They were followed immediately by McDougall's brigade, consisting of what was lately his own battalion, which had no field officers, Ritzema's, Smallwood's, and Webb's. The troops formed along the brow of the hill, and stood waiting for the enemy. The two-gun battery brought up at the same time was Captain Alexander Hamilton's. [Footnote 212: See letters of these officers, _Documents_ 17, 22. Also Tallmadge's account, _Document_ 26.] [Footnote 213: "October 29th [28th] the British advanced in front of our lines at White Plains about 10 o'clock A.M. I had just arrived on Chatterton Hill in order to throw up some works when they hove in sight; as soon as they discovered us they commenced a severe cannonade but without any effect of consequence. General McDougal about this time arriving with his brigade from Burtis's and observing the British to be crossing the Bronx below in large bodies in order to attack us, our troops were posted to receive them in a very advantageous position. The British in their advance were twice repulsed; at length, however, their numbers were increased so that they were able to turn our right flank. We lost many men, but from information afterwards received there was reason to believe they lost many more than we. The rail and stone fence behind which our troops were posted proved as fatal to the British as the rail fence and grass hung on it did at Charlestown the 17th of June 1775."--_Colonel Rufus Putnam, Document_ 43.]
