Carpenter was a member of the
Society of Friends, or
Quakers which influenced, and distinguishes, his non-combat service in the Revolutionary War. Because of their refusal to pay military taxes or fight in the war, Quakers, who had been generally admired for their honesty and simple living in the North American colonies, were looked upon differently when the Revolutionary War broke out, and some were exiled for their beliefs. Some Quakers chose to support the wartime effort, resulting in rifts within the Friends religion; some enlisted for military service, and were expelled from the Society. Some provided financial aid, medical assistance, or supplies at the individual or community level, and a few like Carpenter found ways to assist the combat effort at higher levels without bearing arms, as he did by serving in legal, financial, and logistical roles at the highest levels within
a rebelling colony which bore a key central role in the Revolutionary War. During the American retreat from the banks of the
Assunpink Creek on January 3, 1777, in the
Second Battle of Trenton, Carpenter withdrew all of his supplies and assisted another unit to do likewise and then, exhausted, camped with them. He 'loaned' his coat to an officer who had misplaced his and bedded down in his blanket. Later that night, a messenger awoke them and informed them that they were now stragglers because the rest of the army had retreated. Suffering from the bitter cold without his coat, Carpenter made his way back to his unit. His actions helped General
George Washington continue the fight threatening the rear area of the British forces. An example of a surviving document mentioning Carpenter is a dispatch dated at Burlington, January 17, 1780, from
Light-horse Harry Lee to "Thomas Carpenter, purchasing commissioner" reading in part, "I have written to the Magistrates of Salem County begging them to aid you …" and ends with, "For God's sake perform this business with all possible dispatch." ==Post-revolution==
