He did not support the Mexican War and he felt that if he paid, that he was technically supporting it. I just read Civil Disobedience and it was very hard for me to understand. Thoreau seems to babble on and on, and then contradict himself.
But, I do know that he did not like the Mexican War and that he spent one night in jail for not paying his taxes. He would've stayed longer, but family members paid the tax for him.
SO THE ANSWER IS HE WAS SENT TO JAIL
