n troops came down, and which Lee had planned.
There are alterations and additions in Putnam's and Knox's lists,
which are to be followed where they differ from the list of March
24th. Although many other works were erected, no names appear to have
been attached to them, those only being designated which occupied the
most important points and were provided with guns and garrisons.

The Hills map is indispensable in this connection. John Hills,
formerly a British engineer, surveyed the city and island of New York
as far as Thirty-fourth Street in 1782, and in 1785 made a careful map
of the same, which John Lozier, Esq., presented to the Common Council
in 1847. This is still preserved, and is consulted at times for
official purposes. In addition to giving all the streets, blocks,
docks, and squares, Hills added all the works thrown up in and around
the city during the Revolution, giving their exact location and shape.
Part of the lines have a confused appearance, but they become clear on
referring to the following memorandum on the map: "All the works
colored yellow were erected by the Forces of the United States in
1776. Those works colored Orange were erected by Do and repaired by
the British Forces. Those works colored Green were erected by the
British Forces during the War." In the map of New York accompanying
the present work, Hills' "yellow" line has been followed, showing all
the American forts. Their location corresponds precisely with that
which Putnam gives, so far as he names them; and by projecting the
present streets over Hills' plan, it is possible to ascertain where
they stood in the plan of our modern city.]

GRENADIER BATTERY.--This was a "beautiful" circular battery, situated
on the bank of the North River where it ran out into a well-defined
bluff, at the corner of the present Washington and Harrison streets.
Captain Abraham Van Dyck's Grenadier Company of New York City
Independents built it while Lee and Stirling were in command, and
received the thanks of Washington in general orders for the skilful
manner in which they had executed their work. The fort mounted two
twelve-pounders and two mortars. The grenadier company was organized
by Stirling a few years before, when he lived in New York, and he
watched the construction of the battery with considerable pride. The
_Pennsylvania Gazette_ of May 8th, 1776, contains a letter from
Captain Van Dyck to Stirling, informing him of the completion of the
wor
