The Marylanders were called to battle before sunrise on August 27, 1776. Lord Stirling, the temporary commander of the Maryland troops, was awoken at around three o’clock in the morning and given the news that the British had begun their advance. During the night, the British had surprised the American guard posted near the Red Lion Inn, and in the confusion, a number of Americans had been taken captive. General Israel Putnam ordered Stirling to take the two regiments “nearest at hand” and engage the British on the road near the Red Lion Inn.
Early in the morning on August 27, the alarm guns of the American lines sounded and the troops set to preparing the defense. Under General Putnam’s orders, Lord Stirling marched the First Maryland Regiment and Haslet’s Delaware battalion to meet the British. They were joined by Colonel Atlee’s Pennsylvania troops, Huntington’s Connecticut Continentals, and Kachlein’s Pennsylvania riflemen.
