Many of the American dead were buried at the Flatbush Reformed Dutch Church Complex, although occasionally remains were discovered in the area for years afterward.
It is marked by the small Dongan Oak Monument, which commemorates the boundary tree felled and used as a barricade by the American defenders against the northward invasion.
[9][10][11] An emphasis on naturalistic landscape architecture in the park's original design discouraged a large memorial,[7] and the site is little-noticed today.
[19][20] Raymond Ingersoll put up some temporary markers in the 1910s for Battle Pass and other Revolutionary sites in the park that have since been lost,[21] several written by Charles M. Higgins,[22] who also proposed a more elaborate series of Battle of Long Island monuments, including the placing of Revolutionary era cannon or captured cannon from Imperial Germany on Redoubt Hill .
The Dongan Oak Monument with its bronze eagle atop a stele was dedicated on Evacuation Day 1922,[24] designed by Frederick Ruckstull and sponsored by the Saint Nicholas Society of the City of New York.
