Originally published in 1979, this was the first biography of Jonathan Potts, a prominent Pennsylvania Quaker and physician who served in the Continental army during the Revolutionary War. It was also the first study to be published since 1931 of the role of medical doctors in the northern campaigns. No detailed memoir by an army physician or surgeon has survived to document the conditions they faced. The military career of Dr. Potts, reconstructed here from source materials, including first-hand accounts by Potts and his contemporaries provides considerable information to fill this historical gap.
