Pierce’s health began to decline again in mid-1869; he resumed heavy drinking despite his deteriorating physical condition. He returned to Concord that September, suffering from severe cirrhosis of the liver, knowing he would not recover. A caretaker was hired; none of his family members were present in his final days. He died at 4:35 am on Friday, October 8, 1869, at the age of 64.
