campaign scenario setup help

[valo2000]

here is the situation after 10 turns. i am slowly pushed back in the center but the regulars there are in open ground and under constant fire so they have a hard time advancing.

in the middle the ghurkas are also crawling forward und mortar fire.

Inthe north the ghurkas are beaten back but still have some fight left and need constant reminders by mortar that they better stay back.

I am thinking about storming forward here but the 3 Matildas that are advancing make me change my mind.

Also in the south 3 more matildas attack. I have nothing to stop them.... maybe they will run on a mine or get stuck in the rough terrain.

If i have to retreat to the trenchlines the cw units will be advancing on rough terrain which will give them better cover so i try to hold on as long as possible before going back.
