I chose this one for its rarity. An after action photograph of damage to a Confederate ship, "an aircraft carrier", the CSS Teaser.

"While engaging USS Maratanza at Haxall's on the James on July 4, 1862, a Union shell blew up Teaser's boiler and forced her crew to abandon ship. When seized by Maratanza, Teaser was carrying on board a balloon for aerial reconnaissance of Union positions at City Point and Harrison's Landing."

You can see a large gun barrel in the background.
