W. W. (William Worthy) Day

Born in 1839 and later buried in Steele County, Minnesota, William Worthy Day served in Company D of the 10th Wisconsin Infantry during the Civil War. Records connected with his grave identify him as a Union soldier who was captured at Chickamauga in September 1863 and later endured imprisonment in the South.

Day is known as the author of Fifteen Months in Dixie; Or, My Personal Experience in Rebel Prisons, a memoir of his wartime captivity. The book is especially associated with his time as a prisoner of war and with the ordeal of Confederate prison camps, including the world of Andersonville that made such narratives unforgettable for later readers.

Because reliable biographical material on his life outside military service is limited in the sources I could confirm, the clearest picture of him comes through that memoir: a veteran writing plainly about endurance, suffering, and what he saw firsthand. For readers interested in Civil War testimony, his work offers an immediate and personal voice rather than a distant historical summary.
