Battle of Mamaroneck Overview and History
During the withdrawal from Harlem Heights to White Plains, American forces abandoned the village of Mamaroneck, New York, which was about 12 miles southeast of White Plains.
Soon after, Major Robert Rogers and his Loyalists, known as the “Queen’s American Rangers,” carried out a raid in the area. Rogers and his men — around 500 of them — camped near New Rochelle, which was close to the right wing of the British Army. From that camp, Rogers and his men raided Patriot supply depots and attacked local militia forces.
On October 22, Colonel John Haslet led an expedition of approximately 750 American troops, including men from his Delaware regiment, Virginia, and Maryland, from White Plains to Rogers’ camp near Mamaroneck.
Rogers, a Loyalist who was recognized as a hero of the French and Indian War, was an experienced officer who expected an attack. In preparation, he placed a sentry and 60 men outside of his camp. Haslet’s advance force took the sentry by surprise but was then surprised by Rogers’ men, who were hiding, and the battle started.
The Americans quickly overwhelmed Rogers’ men. They took prisoners and captured weapons and supplies. However, when the sounds of battle reached Rogers’ camp, his men quickly ran to reinforce their compatriots. When they arrived, they chased the Americans away.
Although the American raid was successful, Rogers and his men were able to hold their position outside of Mamaroneck. Six days later, on October 28, British forces attacked the Continental Army at the Battle of White Plains.
