What did the Capitol do to Peeta Mellark Johanna and Beetee?

Peeta is captured by the capital, so that they can use him Katniss. They torture Peeta, and make him try to convince Katniss that a war is not a good idea, and that President Snow should still lead. The capital will go to any lengths of torturing Peeta, to break Katniss, and end the rebellion.

Poor Peeta :(
