West Morass
Battlefield
The West Morass is a marshy depression within Monmouth Battlefield State Park that played a critical role in shaping the battle on June 28, 1778. This wetland area channeled troop movements and served as a natural defensive feature that both armies had to contend with.
What Happened Here
The West Morass was one of the defining terrain features of the Battle of Monmouth. The marshy ground, fed by streams and springs, created a natural barrier that funneled troop movements and made direct frontal assault difficult. Washington used the morass as an anchor for his reformed defensive line, positioning troops so that the wetland protected one flank. British counterattacks had to navigate around or through the marshy ground, disrupting their formations and exposing them to American artillery and musket fire. The morass remains a visible landscape feature within the state park, and interpretive materials explain how the terrain influenced the tactical decisions of both commanders. The preservation of this wetland is essential to understanding why the battle unfolded as it did.
