If pursuers contact any fresh enemy in their path, this is treated as a charge on the contacted enemy. ... Combat is adjudicated in the next impact phase

So, if you are facing a BG which breaks and "gets away", your pursuit takes you into a fresh enemy BG does this contacted BG get the opportunity to evade?

We have been playing that it does, but I don't think it is particularly clear and could probably do with being made crystal clear.

??? Non-shock cavalry, camelry or light chariots entirely 1 base deep or Skirmishers that would be contacted by enemy pursuers in any phase can evade. (See P.30). Skirmishers that would be contacted by pursuing non-skirmishers in open terrain must pass a CMT not to evade.
