== edit request - H. L. Hunley submarine == 

 Refering to the section "The War -> War on the Water -> Union Blockade -> Confederate Countermeasures" - The article barely mentions the confederate submarine H. L. Hunley.  While I don't think it needs an extensive description, the current phrasing, "The Confederacy experimented with a submarine, but it did not work well," doesn't seem to do it justice.  The same paragraph talks about the introduction of ironclad warships to naval warfare.  While it's true that the submarine was experimental and killed 21 men in three sinkings, it also carried out the first successful submarine attack in sinking the USS Housatonic.  It may not have functioned perfectly but it did fulfill its mission and earned a place in history as a consequence. 

 The entire sentence in question reads: 

 The Confederacy experimented with a submarine, but it did not work well, and with building an ironclad ship, the CSS Virginia based on rebuilding a sunken Union ship the Merrimac." 

 It's awkwardly trying to combine two events.  I would suggest breaking it into two sentances: 

 The Confederacy experimented with submarines, ultimately deploying the ill-fated H. L. Hunley in the first successful submarine attack in the history of naval warfare.  Additionally, the navy introduced an ironclad warship, the CSS Virginia based on the refurbished remains of the sunken Union ship the Merrimac.. 

 Granted that might not be the most encyclopedic description ever, but it is an effort to keep it concise while still mentioning that it 1)actually sunk an enemy vessel and 2)didn't return with any sailors alive.
