The Archbishopric of Munster
Your most protestant holiness, the heretics have sent us an offer of peace. It is most glorious day for our wonderful nation. Our foes have seen the light! The Pope has conceded his defeat. He has chosen to give up what is most valuable to him! He realizes the will of god is no longer behind him or his heathen faith!
"Good. On the battlefield of Lunberg him and his catholic allies collapsed within a matter of moments. The cowards allowed Rome to fall as well, falling into the dark arms of Naples. Gods will is behind us, and he strikes true fear into the heart every foe."
(I'm not sure if this is a bug or a feature, but it sure is awesome! This is in vanilla EU4 and it happened because they sent me an offer of peace. The option to force religion was not available. My casus bali was 'show superiority with unam sanctum)
