Tropes:
- Bring Help Back: Colonel Thalman eventually leaves to get The Cavalry after seeing how hard the zombies are to fight. The others learn about his failure to make it past the zombies when he returns as one of their number.
- Face-Revealing Turn: Strayn finds his nephew Thomas, the drummer of his missing regiment, sitting in the middle of a circle of candles and they note provide an Info Dump about the zombies (who transform people with face paint). Throughout the conversation, Thomas faces away from Strayn and only the right side of their face is visible. When Strayn tries to convince them to leave with him, Thomas turns around to reveal that there is paint on their face, and then bites Strayn.
- Kleptomaniac Hero: Corporal Dawson and the survivors of his unit are fairly plucky characters who are fine with forming a truce with the Union to fight the zombies, but Dawson sheepishly reveals that they looted the bank and several homes in a nearby town.
- Magical Negro: Rebecca is a mute escaped slave who is knowledgeable about the magic behind thwarting the zombies and makes Strayn question some of the Confederacy's beliefs after he falls in love with her.
- Men of Sherwood: The remaining Union enlisted men on the mission and the Confederate prisoners they form a truce with to fight the zombies wipe out the zombies in the climax while taking almost no fatalities of their own.
- Noble Confederate Soldier:
- Many minor or secondary Confederate characters are sleazy or thuggish, but the government's main representative, Colonel Strayn is a brave and affable man who (eventually) admits that slavery is wrong but still believes that the Confederacy is a glorious government that should be preserved. However, the epilogue notes that Strayn's new anti-slavery beliefs were very rare and unpopular amongst the Confederacy's officer corps.
- Corporal Dawson and his men are looters, but they happily surrender to and then fight alongside the Union soldiers to get away from the zombies and never show any prejudice toward Rebecca.
- Our Zombies Are Different: The film features voodoo zombies transformed by the tribal magic of slaves. They are capable of carrying on rational conversations, and can transform people with face paint and bites (although the latter are treatable).They are driven to turn more people and conquer territory, and becoming a zombie makes someone uncontrollably violent and ambitious, but their original personality can return as they die. They can be resurrected after taking fatal wounds and sometimes kill each other. They can survive most wounds, but silver and fire are fatal to them.
- Tagalong Reporter: The Union patrol and their Confederate prisoner are accompanied by a clumsy civilian photographer.
- Walking Shirtless Scene: The burly Strayn is introduced bare-chested, doing chin-ups in his prison cell.
- War Crime Subverts Heroism: While the Union as a whole has the moral high ground in the movie, a group of Union soldiers gun down Strayn (who survives with a shoulder wound) and his men (who are turned into zombies afterward) after they surrender.
- We Can Rule Together: Elkins repeatedly tries to get Strayn to join the zombie army and lead it like he did their old regiment.
