Maybe it was love. Or patriotism. Or boredom back home in Minnesota.
There's plenty we don't know about Frances Clayton — a St. Paul wife who dressed up as a man in 1861 and marched off to the Civil War to fight alongside her husband, Elmer Clayton.
Historians say she was among nearly 400 women who cross-dressed their way into battle during the War Between the States. She added the phony name Jack Williams to her disguise, according to one rather reputable source: the Library of Congress.
The national library's website includes an 1865 photograph of Clayton (tinyurl.com/FrancesClayton) fingering a sword in the Boston photography studio of Samuel Masury.
Another of Masury's albumen silver prints from a glass negative survives on the website of Manhattan's Metropolitan Museum of Art (tinyurl.com/FrancesClayton2) saying its photo shows how Clayton "suggestively holds the handle of a cavalry sword between her crossed legs."
Soldiers collected small postcards of that image after the war, according the Met's website. Newspaper accounts from the time offer varying details of Clayton's 22-month service with a heavy artillery company and a cavalry unit out of Missouri. The St. Paul Daily Press said she fought in the Tennessee battles of Shiloh and Murfreesboro.
A Cleveland Plain Dealer newspaper reporter, after Clayton's discharge in 1863, "gained a few facts from Mrs. Clayton … in regards to her romantic history."
She told the reporter she lived in St. Paul with her husband before moving to St. Louis to enlist — "donning a suit of soldier's attire, passing herself off as her husband's brother, and escaping detection."
