Manalapan Township in Monmouth County, New Jersey — The American Northeast (Mid-Atlantic)
Locating the Continental Artillery on Combs Hill
The Battle of Monmouth • June 28, 1778
Inscription.
General George Washington, on the advice of Lieutenant Colonel David Rhea who was raised in this area, ordered Major General Nathanael Greene to take a position here on Combs Hill. Greene brought a battery of four cannon and bombarded the British at the hedgerow. Later that day, this position proved ideal for cannonading the British Grenadiers at the Parsonage Farm, causing them to retreat.
The approximate location of Greene’s artillery on this hill, as recorded in historic documentation, has been confirmed using modern surveying techniques and mathematical analysis.
The Capitaine map of 1778 illustrates General Greene’s position, including a battery of four cannon on this hill. To more precisely define the position of this artillery, researchers used a combination of historical documentation, current site topography, years of archaeological data, and “Line of Best Fit” statistical analysis. The archaeological data included accurately-mapped locations of almost 50 pieces of found iron and lead shot.
Greene's artillery was calculated to have been located somewhere along the “Line of Best Fit,” but where? To answer this, the line was extended until it reached the estimated “military crest” of Combs Hill. The military crest of a hill is the position below the actual crest of the hill that prevents troops being exposed as easily-targeted silhouettes, yet maintains a good vantage point.
The actual location of the center of the artillery line – a battery of four cannon commanded by Lieutenant Colonel Thomas Antoine Mauduit, Chevalier du Plessis – is approximately 75 feet west (left) of this exhibit.

— The exact locations of found ammunition, represented here by yellow and blue circles, provided the raw data for the Line of Best Fit statistical analysis. The red line on this illustration is the calculated “Line of Best Fit.” The blue cone represents the spread of the shot.
— When the results of the research and calculations were overlaid onto Capitaine’s map, the accuracy of this section of the 1778 map is evident.

This position is where, about halfway through the artillery duel Major General Nathaniel Greene positioned 4 Continental cannons under the command of Lieutenant Colonel Chevalier du Plessis-Mauduit. This location put the British in a crossfire between the 10 or more cannon with Washington and these four. This forced Lieutenant-General Sir Henry Clinton and the British Army to withdraw.(Submitted on August 30, 2026, by Richard Peterson of East Windsor, New Jersey.)
2. Battle of Monmouth (Wikipedia).
The Battle of Monmouth, also known as the Battle of Monmouth Court House, was fought near the Village of Monmouth Court House in modern-day Freehold Borough, New Jersey and Manalapan, on June 28, 1778, during the American Revolutionary War.
