author
1863–1941
A historian of the American Civil War, he is remembered for a close study of the Trent Affair, the 1861 diplomatic crisis that strained relations between the United States and Britain. His surviving published work points to a careful interest in politics, diplomacy, and the international side of the war.

by Thomas L. (Thomas LeGrand) Harris
Born in 1863 and died in 1941, Thomas LeGrand Harris is a relatively obscure American author whose best-known work is The Trent Affair, Including a Review of English and American Relations at the Beginning of the Civil War. Library and public-domain records consistently identify him as the author of that book, which was published in the late nineteenth century and later preserved by archives and ebook libraries.
That study focuses on one of the Civil War's most delicate foreign-policy episodes: the seizure of Confederate envoys from the British mail steamer Trent. By centering his work on diplomacy as well as war, Harris stands out as a writer interested not just in battles and leaders, but in the wider international pressures surrounding the conflict.
Reliable biographical information about Harris himself appears to be scarce online beyond his life dates, 1863–1941. Because the record is limited, it is safest to remember him chiefly through his historical writing and his contribution to the literature on Civil War diplomacy.
