I found this battlefield art mural near the corner of 9th Street and 3rd Avenue in Brooklyn. The Google Maps’s street view shows it in better days in 2013.

The mural is on the side of the Michael A Rawley Jr. American Legion Post 1636’s building, which also features a blue historic marker on the front of the building stating: “MARYLAND HEROES: Here lie buried 256 Maryland soldiers who feel in the Battle of Brooklyn, August 27, 1776.”
This August 25, 2012 story in The New York Times gives some details about the battle and the uncertainty surrounding the location of the soldiers’ mass gave.
James Schmitt notes in this blog post that an archaeological survey of the (formerly) vacant lot next to the American Legion Post in 2017 didn’t turn up any human remains.
While time has obscured where these soldiers rest, they are remembered for bravely covering the American retreat.
