 As dawn came , the army approached a stream called Stony Brook . The road the army took followed Stony Brook for a mile farther until it intersected the Post Road from Trenton to Princeton .

The road was not visible from the Post Road , and ran through cleared land to a stretch from which the town could be entered at any point because the British had left it undefended .
