On the ISth, the whole British army crossed to Pelham Point, and marching northerly, encamped the s:i,uie night on the high ground between Hutchinson's River and New Rochelle village, where it remained till the 21st. On the 21st, the British removed and encamped on New Rochelle heights, north of the village, and on both sides of the road leading to Scarsdalc. This camp was broken up on the 25th, and the army moved forward to a position upon the high grounds in Scarsdale, in the vicinity of the late John Bennett's farm, and there remained till the morning of the 28th of October.
General Washington during that time had not remained inactive -- as early as the 11th of October, a part of his army crossed from Harlem heights, readied White Plains on the 12th, and commenced erecting fortifications ; and on the 22d General Washington, leaving his head-quarters at Fo^t Washington, established them at Valentine's hill, whence they were removed to White Plains on the 23d.
"The entrenchments at White Plains were erected under the directions of a French engineer, and consisted of a square fort of sods in the main street with breast works on each side running westerly over the south side of Purdy's hill to the Bronx, and easterly across the hills to Horton'a pond. When tiie Englisli attacked Chattcrton's hill on the 28th. they were unfinished; but during t!ie night of the 2Sth and 29th of October they were raised and strengthened, being onlyintended for temporary use until the position above Abraham Miller's in North Castle could be fortified, which was done, and to which the American army afterwards retired.
