Compulsory Retreat of CM/CL/CGL with Support Infantry

This has probably been answered before but we had a situation recently where a CM was in melee with an enemy infantry unit. The CM had support from a friendly FL unit. The melee was a draw and the CM made a compulsory retreat. What happens to the FL support unit? Does the FL also retreat from the melee disordered with the enemy infantry remaining pat (as it can't follow up a compulsory retreat.) Or does the FL remain in the melee subject to future rounds of combat (all things remaining the same) as the main unit?

I don't have my stuff handy but I thought it had been changed to a "may" retreat for the CM vs Infantry?

Thus any CM retreat would be voluntary so the supporting FL stick in place.

"May" retreat is correct. Which would argue for one understanding. But, on the other hand, the main unit is retreating from the melee. The rules also say that when the main unit retreats any support units also retreat.

Just to be clear, I have no personal axe to grind in this question. I can see both arguments.

I think the second option is correct - the CM MAY choose to remain in contact but should they retreat then the retreat rules kick in and the supporting unit also retreats

as Cyrus said

Thanks for the clarification.

As an aside, if we reversed the above scenario and the FL was the main unit in the melee and it was supported  by a CM against enemy infantry and the FL lost the melee and retreated what retreat move would the CM make? Would it be a regular 1d6 or would it be a compulsory retreat 5+1d6? Could the enemy infantry pursue in this scenario?

Interesting

Easy bit first
Irrespective of how far the CM retreated I would say the opposition could follow up assuming they are normally allowed to do so.

The harder bit
I think the CM would retire the normal D6 rather than the 5+d6 as they only fought as supports rather than as the main opponent

I'm inclined to agree with your thinking Cyrus. These are the kinds of details I hope Lorenzo will include in Impetus 2.

I will have to file that interpretation away for our competitions. It's certain to come up at some stage.

Yes will have to file that one away. As a side issue the retreat no longer disorders is that right ?

"Amendment to paragraph 7.6.2
In the case of a draw against Infantry, the player controlling
any CM/CL/CGL Units involved in the melee can
choose to retreat by 5U+1d6 or remain in contact."

Just thought I'd bring it up as this has been asked just recently. Old rule says "....in disorder"

We continue to play that CM/CL/CGL that make a compulsory retreat from a draw become disordered if they are not already. Interesting to see if this is correct.

I would say yes, the new rule doesn't supersede the original totally, just adds an option to remain in contact, so if you choose to retreat as per the original rules you still become disordered (sadly for my Persians)

Good way of putting it Cyrus. The change in the rule requires clarification and a new term (compulsory retreats are no longer compulsory!)

Ok good think we're in agreement it's just been overlooked in the amended version.
The new wording should be.
