1830–1899
Best known for a firsthand Civil War chronicle, this nineteenth-century writer left behind a compact but vivid record of soldiers’ lives in the 159th New York State Volunteers. His surviving work feels direct and practical, shaped by experience rather than literary showmanship.

by Edward Duffy
Edward Duffy was a nineteenth-century American writer remembered for History of the 159th Regiment, N.Y.S.V., a short regimental history compiled from his diary and published in 1890. The book was reprinted from material that had appeared in the Hudson Gazette, and it presents the movements and experiences of the 159th New York State Volunteers during the Civil War.
The surviving record identifies him as Lieut. Edward Duffy and links him closely to the regiment whose story he told. That background gives his writing a grounded, eyewitness quality: instead of a grand overview, he offers the kind of concise military narrative that preserves marches, battles, and the everyday strain of service.
Beyond that work, reliable biographical details are limited in the sources I could confirm here. Even so, his book has endured as a useful personal and historical document, valued for turning a soldier’s diary into a readable account of one Union regiment’s war.
