THOMASTON – Jonathan Cilley, a young congressman from Maine, stood at the ready with his pistol at his side nearly 100 yards from his challenger in a field outside of Washington, D.C. The date of the duel was Feb. 24, 1838.

Cilley, who had no particular dislike for his opponent, intentionally fired the first shot into the ground. Additional rounds were ordered. After the third, Cilley lay mortally wounded in the frozen field, leaving a wife and three young children back home in Thomaston.

Much of Cilley’s life leading up to its tragic end, and the lives of his survivors and descendants, have been reconstructed from a cache of letters that had been preserved in almost pristine condition by the family for generations.

The 500 letters, written in flowing longhand and occasionally penned on top of earlier correspondence to save paper that was so precious at the time, have been painstakingly deciphered over five years by historian Eve Anderson and a small team of owl-eyed assistants.

Now appearing in a book, “A Breach of Privilege, Cilley Family Letters 1820-1867,” they paint a detailed and personal portrait of a Maine family in words no outsider could have chosen.

The letters fell into Anderson’s hands after a descendant of Cilley’s e-mailed her at the Thomaston Historical Society, where she is president, and asked if she would be interested in transcribing them.

Intertwined within the pages are themes of family love, religious tensions, political corruption, broken friendships, the prevalence of disease, and what turns out to be a planned killing of a promising young politician. Cilley’s duel created such a public outcry that it resulted in a law to end the practice.

Anderson, interviewed in her 1800s house just down the street from the Cilley home that remains occupied to this day, said her book should be seen as more than a dusty collection of letters of interest to history buffs and scholars.

“I wanted the book to be looked at as a novel that happened to be true,” Anderson said of her first book.

Anderson, who studied English literature and history in college, free-lanced for her local newspaper while raising her children at home in Connecticut. She and her husband retired in Maine.

Cilley was born in 1802 in Nottingham, N.H. As a young man he came to Maine to attend Bowdoin College in Brunswick, where his classmates and friends included Nathaniel Hawthorne, distant cousin Henry Wadsworth Longfellow and Franklin Pierce, who would become president.

In passages that would sound familiar to a parent with a son or daughter in college today, Cilley requested money again and again to meet his expenses. He bantered playfully with his beloved sisters, needling them to write more.

He wrote that he had fallen in love – “yes, that is in LOVE – deep in love – up to the verry (sic) tip of my nose in Love – which, you know, tips down a little.” But he teased his sister Ann for months before revealing the name of the object of his affections, Deborah Prince.

In a curious play on words that eerily foreshadowed his doom, Jonathan wrote of a housemate who entered his room with “a pistol heavily loaded and pointing it exactly at me.” Only later did he reveal he was referring to an “a-pis-tol,” or epistle, a letter from home.

As time went on, the tone became more serious as politics became a central part of Cilley’s life. He expressed pride in his native state in 1832 as it presented “an undivided front for [Andrew] Jackson and [Martin] Van Buren.”

Writing to his wife Deborah from Augusta, where he served as speaker of the Maine House of Representatives, Cilley referred to his enemies and expressed hope that God will “give me wisdom & strength sufficient for every trial.”

Serving in Washington after he was elected to the U.S. House, Cilley’s exchanges with Deborah reflected an unflinching devotion to her and his children. He described the splendors of the nation’s capital in colorful detail.

Deborah, showing signs of tuberculosis and bipolar disorder as she raised three young children, expressed her support and encouragement, writing that “you know not what a comfort your letters are to me.”

As north-south antagonisms grew, a plot was hatched to silence the rising young abolitionist from Maine. A remark by Cilley on the House floor, in which he alluded to a bribe to a New York newspaper publisher, gave Cilley’s enemies the opportunity they sought.

Kentucky Congressman William Graves was goaded into challenging Cilley to a duel. Cilley, while he disapproved of such action and liked Graves, said New England honor was at stake and agreed. The two met on a field in Maryland.

After the first two shots were exchanged and a third was demanded, Cilley turned to an associate and said, “They thirst for my blood,” according to a letter from Franklin Pierce to Deborah’s brother, Hezekiah Prince Jr.

The transcribers were stumped for more than three weeks trying to decipher a letter written on Feb. 22, 1838, which gives Cilley’s explanation for accepting the challenge, Anderson said. In the letter, the congressman wrote, “If a man is to live free and boldly, he must take his life into his hands.”

Anderson said it wasn’t until she saw another letter with a “dly” ending that she could make out the word that turned out to be the key to the sentence.

“I looked at it and it said ‘boldly.’ It jumped off the page at me,” she said.

A letter that was written 180 degrees across an earlier letter as a way to save paper took a month to transcribe. Other letters were written in the margins of previous ones.

The quality of penmanship told the transcribers a lot about the writers, Anderson said.

“You could see Debbie’s writing deteriorate because of her tuberculosis.”

The letters chronicle the growth and maturation of Jonathan and Deborah’s three surviving children, Greenleaf, Prince and Julia, from the time Greenleaf first picked up a pen through their college years and beyond.

Letters from Prince, who was called Prin, highlight the personality similarities between himself and his father. His letters are among the few that make reference to Jonathan Cilley after his death.

Anderson said she tried to let the subjects tell the story of the Cilley family as much as possible, but she provides sufficient historical background and interpretation to give the letters perspective.

While the editors made some changes in punctuation and paragraphing to make the letters more readable, original spelling and grammar were retained for the sake of authenticity. One of the transcribers is an expert in 19th century expressions.

Many of the earlier letters are written in cumbersome and complex grammatical style, but as the years passed and language evolved, the writings become more clipped and direct, with fewer flowing, flowery expressions.

The letters also reflect a change in outlook between the first half of the 1800s and the Civil War era, due mostly to advancements in medicine and transportation and new inventions that made life easier.

“The original letters showed that people thought they were being put on Earth to be tested and see how much they could manage to survive through,” Anderson said.

“But their general outlook even during the war was more upbeat. They saw a better future. Life was getting easier for them,” the author said. “The tone of the letters was optimistic.”

Greenleaf went on to become a naval commander and Prin a brigadier general during the Civil War.
