The disease was probably smallpox or bubonic plague, as an eyewitness account given by Samuel Pepys states that Cambridge was "full of spots" and that his physician, Dr. Frazier, did not know how to treat this disease. On 30 May, Kendal, who was also sick from convulsions, died at St. James's Palace and Cambridge was transferred to Richmond.
