[Footnote 34: General Orders, April 16th, 1776: ... "Colonel Prescott's Regiment is to encamp on Governour's Island as soon as the weather clears. They are to give every assistance in their power to the works erecting thereon."...] [Footnote 35: "Monday night 1000 Continental troops stationed here went over and took possession of Governor's Island and began to fortify it; the same night a regiment went over to Red Hook and fortified that place likewise." _New York Packet, April 11, 1776._] The occupation by Putnam of these two points, which was clearly necessary for a more effective defence of the East River, required, or at least resulted in, the modification of Lee's plan, and the adoption of a new line on Long Island. It was now decided to hold the Brooklyn peninsula with a chain of works thrown up across the neck from Wallabout Bay to the Gowanus Marsh; and it was in this vicinity that the encampment for Greene's brigade was marked out by Mifflin, the quartermaster-general, and afterwards approved by Washington.[36] By the fortunate recovery of the daily orders issued by General Greene on Long Island, and also of original sketches of the site, it has become possible to fix the location of this line and the names of the works with almost entire accuracy. [Footnote 36: General Orders, April 25th, 1776: "The encampment of the Third Brigade to be marked out in like manner, upon Long Island, on Saturday morning. The chief engineers, with the quartermasters, etc., from each regiment, to assist the quartermaster-general in that service. As soon as the general has approved of the encampments marked out, the troops will be ordered to encamp...."] To defend the approach between the bay and marsh, the engineers laid out three principal forts and two redoubts, with breastworks connecting them. The site occupied was a favorable one. On the left rose the high ground, now known as Fort Greene Place or Washington Park, one hundred feet above the sea-level; and on the right, between the main road and the marsh, were lower elevations on lands then owned by Rutgert Van Brunt and Johannes Debevoise. The flanks were thus well adapted for defence, and they were near enough each other to command the ground between them. Two of the works were erected on the right of the road, and received the names of Fort Greene and Fort Box; three were on the left, and were known as the Oblong Redoubt, Fort Putnam, and the redoubt "on its left." In view of the fact that local historians heretofore have put but three fortifications on this line, where, it is now well established, there were five, a more particular description of them becomes necessary. Extending from right to left, they were laid out as follows:[37] [Footnote 37: Consult map accompanying this work, entitled "Plan of the Battle of Long Island, and of the Brooklyn Defences in 1776;" also the note in regard to it under the title "Maps," in Part II.]
