Combat in bad going

Hi There

We are getting along pretty well wit the rules now but still have a few things crop up

Psiloi were half in and half out of a wood
Front of base was in good going but back half of base was in the wood, so base counted as being in bad going
They were attacked by some cavalry who were totally in good going

Combat happened
Psiloi got no penalties for being in the wood
Cavalry got no penalties for being out of the wood

Psiloi last combat

Two chains of thought occured

I thought that Psiloi got away, reasoning being they were in bad going and if they had been a Blades for e.g. they would have had a penalty of -2 for being in an area of bad going

Other view was that Psiloi were destroyed because the cavalry were in good going

Fairly sure I was correct

If the Cavalry had been half in and half out of the wood and Psiloi had been in good going and the cavalry had won the Psiloi would have been destroyed as combat outcomes are about position of the looser rather than the winner

Hope some of this makes sense because as I type it I am not sure it does
