The lorce.on the summit of Chatterton's-hill, which had thus, insensibly, arrested the progress of the Royal Army, in its movement against the Right and Center of the American lines, was, of course, that of whom we have already made mention -- the Regiments commanded, respectively, by Colonels Brooks and Haslet, the lirigade commanded by General McDougal not having reached the hill ; and against that small force, the Hessian Artillery, from the Plain, on the opposite side of the Bronx, not far from the present railroad-station, at the White Plains, opened a vigorous fire,' with no other effect, however, than the wounding of one of the Militia, which so greatly alarmed his comrades that the entire Regiment " broke, and fled, and were not rallied, without nuich " difhculty.'"- Soon after the cannonade was commenced, General McDougal and his command reached the hill-top ; and the command of the entire force devolved on and was assumed by that very inexperienced Officer. After several changes, in the positions ofthe several Regiments, the line was formed, with the Regiment of Massachusetts Militia, commanded by Colonel Brooks, sheltered by a stone wall, and supported by the Regiment of Marylanders commanded by Colonel Smalhvood -- the latter, the remains of that fine body of " Maccaroiiies," so called by the New Englanders, whose gallant conduct, at the Battle of Long Island, had won the admiration and sorrow of General Washington, and which has been generally honored in history -- on the extreme right, confronting Colonel Rail and his Brigade, who were resting on their arms, on the summit of the adjacent hill, further to the southward. On the left of the Marylanders, was posted the Delaware Regiment, proud of its name of " The Blue Hen's Chickens," whom Colonel Haslet commanded : the remainder of General McDougal's Brigade, composed of the First Regiment of the New York Line, formerly commanded by Colonel McDougal, at that time, by one of its Captains, whose name was not recorded ; the Third Regiment of the same Line, commanded by Colonel Rudolphus Ritzema ; and the Regiment of the Connecticut Line, commanded by Colonel Charles Webb, occupying the left of the very feeble line^ -- with the exception ofthe Regiment commanded by Colonel Brooks, no portion of that force was composed of Militia : all, except that Regiment, were Continental troops.* The
