Gentle Bishops

Clouds of war have fallen over this once peaceful village. Recently neighbors and goodwill reigned. Now, there are only enemies and bitter lifelong hatreds. The warring kings have ordered their clergy to take to the battlefield and capture the opposing abbey... whatever the costs may be.

These people of the cloth have spoken liege vows to their king. They have also taken holy vows not to shed another's blood. They need your help to honor both sets of seemingly irreconcilable vows.

The object of this puzzle is to exchange the black and white bishops using standard chess moves. However, you may not place a bishop in a position where it could be captured by an opposing bishop.
