Maryland 400

A wooden house, or possibly a mill, is surrounded by battle. The smoke and haze of battle obscures much of the background, but formations of red-coated soldiers are visible through it. Small figures, some clearly uniformed, others not obviously so, fight in the foreground.

The Maryland 400 were members of the 1st Maryland Regiment who repeatedly charged a numerically superior British force during the Battle of Long Island during the Revolutionary War, sustaining heavy casualties, but allowing General Washington to successfully evacuate the bulk of his troops to Manhattan. This action is commemorated in Maryland's nickname, the "Old Line State." A monument in Brooklyn and multiple plaques were put up in the memory of this regiment and the fallen soldiers.
