Had a game recently where I charged some LF with Cav who evaded. They evaded towards a group of LH moving in column along their rear, didnt have enough to clear the LH so stopped with one rank on one side and one on the other. My cav pursued and hit the LF in the rear and broke them. The LF then fled at the end of the turn at which point I pursued and hit the LH column in the flank.

Is this correct?
Is there an an impact combat and if so when? (there has already been one this turn which lead to me being in that position)?
If the situation is fought as an impact combat in the next turn what happens in my Mellee phase?
When would the LH conform?
Would they drop a level for being charged in the flank?

The LH evade unless they choose to take a CMT not to evade and pass.

If they stand, you have a flank charge fought next Impact Phase.
