You can read more about the Hessian raids and occupation of Moorestown from Moorestown and Her Neighbors, by George Decou, online courtesy of the West Jersey History Project.
Chapter 6, "Revolutionary Days", describes events in and around Moorestown:
"During the British occupation of Philadelphia, foraging and marauding parties frequently raided the farms in the neighborhood of Moorestown. Bells were rung at their approach and horses and cattle hurriedly driven to the woods and hidden until the raiding party disappeared."
"...'another portion of the army on the same day marched up King’s Highway, through Ellisburg and camped that night in and near the Friends’ Meeting House in Chester.' The record also states that 'they plundered the inhabitants of their household goods, their grain, horses and cattle in that section of the State at every opportunity.'"
"The officer in command of the Army occupied the home of Richard Smith now standing at No. 12 High Street, According to tradition chickens were killed and dressed in the parlor and the soldiers feasted and reveled far into the night. The commander ordered the ladies of the house to stay in a certain room on the second floor, otherwise he would not be responsible for their safety." It continues: "The Hessian General Knyphausen... no doubt displayed his usual table manners for he was accustomed to use his thumb to spread the butter on his bread."
