Wikipedia
Bounty jumpers were men who enlisted in the Union or Confederate army during the American Civil War only to collect a bounty and then leave. The draft of 1863 allowed individuals to pay a bounty to someone else to fight in their place rather than be drafted. Bounty jumpers commonly enlisted numerous times in the army, collecting many bounties in the process.
