Dickinson resigned his commission in December 1776 and went to stay at Poplar Hall in Kent County. While there he learned that his home on Chestnut Street in Philadelphia had been confiscated and converted into a hospital. He stayed at Poplar Hall for more than two years. The Delaware General Assembly tried to appoint him as their delegate to the Continental Congress in 1777, but he refused. In August 1777 he served as a private with the Kent county Militia at Middletown, Delaware under General Caesar Rodney to help delay General William Howe's march to Philadelphia. In October 1777, Dickinson's friend, Thomas McKean, appointed him Brigadier General of the Delaware Militia, but again Dickinson declined the appointment. Shortly afterwards he learned that the British had burned down his and his wife's "Fairhill" property during the Battle of Germantown.
