The Confederate Ironclad is a 1912 short spy film set during the American Civil War.

Confederate Lieutenant Yancey is asked by Mary de Lane to meet her orphan Northern niece, Elinor.

She promptly writes a letter to the "Commanding Officer, U.S. Gunboats", revealing the location and the fact the fort guarding it is "defenseless for want of powder".

The Confederates emerge victorious; one gunboat is set afire, forcing the crew to abandon ship.

Kalem had about two dozen piano scores published in 1912–1913, to be sold to theaters for 25 cents apiece.
