As survivors from the sinking Cumberland are being rescued, the Virginia's second challenger, the Congress, can be seen firing at her in the background. The Virginia had bypassed the Congress to attack the smaller ship first. Then the ironclad returned to pit her armor against the more numerous guns of the proud frigate.
