When North and South went to war, millions of American families endured their first long separation. For men in the armies—and their wives, children, parents, and siblings at home—letter writing was the sole means to communicate. Yet for many of these Union and Confederate families, taking pen to paper was a new and daunting task. I Remain Yours narrates the Civil War from the perspective of ordinary people who had to figure out how to salve the emotional strain of war and sustain their closest relationships using only the written word.

Christopher Hager presents an intimate history of the Civil War through the interlaced stories of common soldiers and their families. The previously overlooked words of a carpenter from Indiana, an illiterate teenager from Connecticut, a grieving mother in the mountains of North Carolina, and a blacksmith’s daughter on the Iowa prairie reveal through their awkward script and expression the personal toll of war. Is my son alive or dead? Returning soon or never? Can I find words for the horrors I’ve seen or the loneliness I feel? Fear, loss, and upheaval stalked the lives of Americans straining to connect the battlefront to those they left behind.

Hager shows how relatively uneducated men and women made this new means of communication their own, turning writing into an essential medium for sustaining relationships and a sense of belonging. Letter writing changed them and they in turn transformed the culture of letters into a popular, democratic mode of communication.

One of the cruelest abuses of slavery in America was that slaves were forbidden to read and write. Consigned to illiteracy, they left no records of their thoughts and feelings apart from the few exceptional narratives of Frederick Douglass and others who escaped to the North—or so we have long believed. But as Christopher Hager reveals, a few enslaved African Americans managed to become literate in spite of all prohibitions, and during the halting years of emancipation thousands more seized the chance to learn. The letters and diaries of these novice writers, unpolished and hesitant yet rich with voice, show ordinary black men and women across the South using pen and paper to make sense of their experiences.

Through an unprecedented gathering of these forgotten writings—from letters by individuals sold away from their families, to petitions from freedmen in the army to their new leaders, to a New Orleans man’s transcription of the Constitution—Word by Word rewrites the history of emancipation. The idiosyncrasies of these untutored authors, Hager argues, reveal the enormous difficulty of straddling the border between slave and free.

These unusual texts, composed by people with a unique perspective on the written word, force us to rethink the relationship between literacy and freedom. For African Americans at the end of slavery, learning to write could be liberating and empowering, but putting their hard-won skill to use often proved arduous and daunting—a portent of the tenuousness of the freedom to come.
