Despite having suffered successive defeats, Washington saw an opportunity to entrap and decisively defeat the divided British army. He resolved to attack the Germantown garrison, as the last effort of the year before entering winter quarters. His plan called for a complex, ambitious assault; four columns of troops were to assail the British garrison from different directions, at night, with the goal of creating a double-envelopment. Washington's hope was that the British would be surprised and overwhelmed much how the Hessians were at Trenton.
