SOLUTION: The anachronism in this scene is the electric lamp on the table. This image depicts a Confederate war council during the American Civil War (1861–1865). However, electric table lamps like the one shown — with a visible power cord and outlet — did not exist during that time. Widespread electrification and household electric lighting didn’t begin until the 1880s–1890s, and outlets as shown wouldn’t appear until the 20th century.
