Civil War Pipe Tobaccos

It may be too much to look for historical meaning in pipe blends, but here goes anyway. These are modern blends not pretending to be historical. Courtesy of the Old Virginia Tobacco Company:
Antietam Pipe Tobaccos
Description: American Civil War
Blend of flue cured Virginia & Kentucky Burley seasoned w/ribbon cut black Cavendish. The enticing aroma is from apricot brandy. Slightly sweet & rich, yet mellow. A general's favorite.

Gettysburg Pipe Tobaccos
Description: A soldier's favorite from the American Civil War. Virginia tobaccos and smooth black Cavendish are set with Colombian coffee beans and dark chocolate. The real thing for genuine coffee lovers.
I see wisps of meaning here. The Gettysburg blend alludes to "bummers" off in the weeds brewing coffee when they should be in the firing line. (Civil War soldiers probably drank Mexican, Brazilian, or Javanese coffee so the Columbian reference may be anachronistic.) Col. Wainwright in his diary noted thousands of these slackers in and around Gettysburg while his artillery was en route to battle. Case closed.

Antietam is more difficult. Who is this mysterious general? McClellan smoked cigars. Did Lee smoke? I think not. The Antietam blend must be about Burnisde. Wainwright comments on how maginificently Burnside's HQ was stocked with every kind of alcohol: lager, porter, port wine, madeira, the works. A pleasure to visit the hospitable Burnside, Wainwright said. That was in 1864 but a tiger doesn't change his stripes. Apricot brandy - expect to find it at Burn's place. Kentucky burley - a reference to Burnside's nearby Cincinnati stay? Sweet and mellow. That's how Wainwright characterized his dealings with Burnside. I think we've solved another one.
