Prompt
Generate a realistic portrait of Charles Russell Lowell, a 19th-century American military officer, in a dignified and somber style, reminiscent of Civil War-era photography. Depict him in his mid-20s, wearing a Union Army uniform with the rank of Colonel or Brevet Brigadier General, set against a subtle, muted background that evokes a sense of solemnity. Incorporate a hint of introspection or contemplation in his expression, reflecting his notable contributions to the American Civil War and his tragic death from battle wounds at a young age.
