Just when you thought every word that could be written about the Civil War had been written, every book published, along comes an exciting collection of new information.

Such a happening comes as a new book — still seeking a publisher — from Civil War aficionado J. Mark Powell, content manager at InsideSources, a syndication service.

Before electronic recording devices, letters were the eyewitnesses to history. The discovery of a trove of these is a light beamed into the past.

Powell’s book is a compilation he has made in 20 years of seeking, collecting, chasing down, and sometimes buying unpublished letters from the war. He has collated these and provided just enough annotation to make them an easy and engrossing read.

In all there are nearly 500 letters from every social strata affected by the tumult — from a slave to many tender notes between families torn apart and sometimes divided between North and South. It is history in the raw, modified only by Powell’s scholarship and loving curation.

The letters were written between husbands and wives, between lovers, between parents and children, and between brothers. They provide untrammeled truth or truth reflected by the station of the writers.

It is truth that hasn’t been adulterated for political purposes, then or now, as often happens, with the weaponizing of history.

These letters take the reader into the war, its hope and its horror. It is life as it was lived by ordinary people, soldier and wife, mother and child between 1860 and 1865, through the eyes of people who lived the war, and sometimes died.

Powell told me, “This is the first account of its kind, to the best of my knowledge. It is just a completely unique approach.

“This isn’t a textbook recitation of names and dates and places. I tried to capture how it felt to live through those terrible times. The pride, the hopes, the fears, the uncertainty, and even the humor is all in this collation of the letters for those who endured the war on both sides.”

There are no famous names here, no excerpts from famous generals or major historical figures. Rather, these are the everyday people who lived through the war and, in some cases, didn’t survive.

Powell is a seasoned  journalist who worked for  several local TV stations, CNN, and on Capitol Hill before alighting at InsideSources. He is also the author of a novel and has collaborated on another. He has given much of his life to studying the Civil War — a fascination which began as a 10-year-old.

Powell said his work is also a cautionary tale for 2024, “because the war resulted from two sides that had dug in their heels and refused to budge. Very much the same way America is suffering the hardening of the political arteries right now.”

In one letter from his book, a woman named Genevieve Byrne Runyon lost her husband, James, an officer in the 26th Iowa Infantry in 1862. He had been dead for nearly three years when his regiment returned home.

This is her anguish as she related it to her late husband’s brother in a letter dated Dewitt, Iowa, August 18, 1865:

“I suppose you would like to know how I am getting along. I had my father move into my house and I am keeping house for him. Yet I feel like a wanderer looking for someone that I’ll never see again. It feels foolish to be ever complaining, but I cannot help it. I could write forever on the subject.

“How I felt when the remainder of his regiment returned without him, I cannot describe. I felt I had lost him forever on this earth. Now that the cruel war is over and I look back and see the many lonely homes, I wonder what it all meant.”

Powell, who writes the weekly syndicated column “Holy Cow! History,” told me, “I’ve had that letter for over 20 years now, and that last line still haunts me every time I read it.”
