On December 22, 1775, two of Washington’s soldiers brought a prisoner to his headquarters (司令部). Washington thanked the soliders, then gave an order that the prisoner was to be left alone and that the soldiers were to shoot if the man tried to escape. But when the door was closed, Washington smiled.

The man standing in front of him was John Honeyman, one of the general’s most trusted men. In early November, Washington had given Honeyman orders to travel with the British army as a servant and to stay with it until he had something to tell. Honeyman now had important information. He described the situation in Trenton, giving the exact number and position of the troops there.Trenton was held by several companies (连队) of Hessians(雇佣军). The Hessians were not English soldiers.They were Germans who had been hired by the British to fight in America. According to Honeyman, the Hessians fought only for money. They had done nothing to build up their defences in Trenton. Now they were busy planning a big Christmas celebration.
