Then the Jedi need to plow through to the Hailfires immediately. Vera-Kin is already in striking distance. Would she be able to move in and attack the Hailfire that Xeth damaged in his attack run this turn, while ordering the Selenian Special Forces to move towards them and keeping their fire up on the battle droids?
The other Jedi should have the Selenians finish off the battle droids while moving up to meet up with Vera-Kin at the Hailfires.
You can't 'order' the Selenians to do anything.
You will find that orbital bombardments are very poor ways of taking out individual targets.
You may also wish to consider that if they over-do it they'll collpase the Valley which is no good to them (and is the emergency Selenian contingency had this fight gone to the 'losing' scenario).
