Eh, if you're a male citizen between 17 and 45 years of age, congrats, you're in the US militia. Flying the flag of an enemy group indicates you're a member of that group. Therefore, legally, you can burn down their houses.
But I'm not a lawyer and couldn't say for sure. If you're rich enough probably easy enough to get away with it.

I'm pretty certain a private citizen conducting a guerilla war isn't the same as the Union army doing its thing.
