While Washington was inspecting the terrain to determine where it was best to station his troops, messengers alerted him that the British were advancing. Returning to his headquarters, he ordered the 2nd Connecticut Regiment under Joseph Spencer out to slow the British advance, and sent Haslet and the 1st Delaware Regiment, along with Alexander McDougall's brigade (Rudolphus Ritzema's 3rd New York Regiment, Charles Webb's 19th Continental Regiment, William Smallwood's 1st Maryland Regiment, and the 1st New York Regiment and 2nd New York Regiments) to reinforce Chatterton Hill.
