This marker in Union Township recalls the movement of Crown forces through the former Connecticut Farms area during the Battle of Springfield on June 23, 1780. It refers to the route and wider battlefield rather than proving that General Sir Henry Clinton stood at the marker’s exact location. Modern roads and development cover much of the ground crossed by British, German, Loyalist, Continental, and militia units.

The offensive was the second major British thrust into northern New Jersey that month. On June 7, troops under Lieutenant General Wilhelm von Knyphausen advanced from Elizabethtown toward Morristown, where Washington’s army was based. American resistance at Connecticut Farms and growing militia activity checked the movement. The village was burned, and Hannah Caldwell was killed at the parsonage, an event that intensified Patriot anger.

Clinton returned from the capture of Charleston and joined Knyphausen in planning another attempt. On June 23, approximately 5,000 to 6,000 Crown troops advanced in columns through Elizabethtown, Connecticut Farms, and the Vauxhall and Galloping Hill road corridors. Their strategic goal was to break through toward Hobart Gap and threaten Washington’s position around Morristown. Some accounts attach Clinton’s name to the march because he was commander in chief, while Knyphausen exercised important field command. The marker simplifies a more complicated command arrangement.

American forces under Major General Nathanael Greene defended bridges and road junctions with Continental troops, New Jersey militia, and partisan units. Fighting developed at several crossings as the Crown columns tried to turn the American positions. At Springfield, defenders contested the bridges over the Rahway River. The Americans ultimately withdrew from portions of the village, but continued resistance and militia pressure made further advance costly and dangerous.

British and German troops burned much of Springfield before retreating toward Elizabethtown Point. American militia fired from woods and along roads during the withdrawal. By midnight the expedition had crossed back to Staten Island. The failure ended major British attempts to penetrate northern New Jersey and destroy Washington’s main army.

The marker’s location along the historic route helps explain the battle as a moving series of engagements rather than a single clash. Connecticut Farms, Vauxhall, Galloping Hill, and Springfield formed connected defensive zones. Civilians experienced burning, looting, fear, and displacement as armies passed through. The site therefore commemorates both operational movement and community suffering. Here the final large British invasion of New Jersey moved westward, met increasingly organized resistance, and then receded without achieving its strategic purpose.
