In 1804, Abigail, unbeknownst to her husband, wrote to Jefferson to express her condolences upon the death of his daughter Polly, who had stayed with the Adamses in London in 1787. This initiated a brief correspondence between the two which quickly descended into political rancor. Jefferson terminated it by not replying to Abigail's fourth letter. Aside from that, by 1812 there had been no communication between Monticello, the home of Jefferson, and Peacefield since Adams left office.[291]

John Adams, c. 1816, by Samuel Morse (Brooklyn Museum)
In early 1812, Adams reconciled with Jefferson. The previous year had been tragic for Adams; his brother-in-law and friend Richard Cranch had died along with his widow Mary, and Nabby had been diagnosed with breast cancer. These events mellowed Adams and caused him to soften his outlook.[287] Their mutual friend Benjamin Rush, a fellow signer of the Declaration of Independence who had been corresponding with both, encouraged them to reach out to each other. On New Year's Day, Adams sent a brief, friendly note to Jefferson to accompany a two-volume collection of lectures on rhetoric by John Quincy Adams.
