Right. Here goes...
DH says that if you can go, you should, for the reasons I mentioned. He went further than I did and said that some judges are in fact more indulgent towards the accused if the victim doesn't turn up, because they tend to feel that if the offence was serious, the victim would move heaven and earth to go.
He also said that, for your sake and that of your children, you should try and express your point of view before the court, so that there is a written trace of the truth, rather than allowing your ex-h to present his vision of things and having that go down on record as the only version of events. If you can't make it to the hearing, you should, in DH's view, be represented by an avocat and preferably the best one you can afford. TBH, the cost of adequate legal representation might not be much more than the expense of the trip from Munich .Ideally you would both go yourself and be represented by a good avocat, but that would be very pricy.
Hitting a spouse is, as I was hoping, an aggravating circumstance rather than a mitigating one, so DH supposes that this also applies to ex-spouses, though he'll try and check the code pénal when he has a moment, to be sure. [Why do half of my italics work and not the other half???]
I presume you know this, but if you want to claim compensation for the material/physical/psychological damage, you need to declare yourself a partie civile before the court, since asking for compensation is a different type of proceedings. You can get an avocat to do it on your behalf, but if the formal procedure is not carried out, the question of financial compensation will not be raise. This is because unless you are a partie civile the judge's task is to punish the accused in the name of society on the whole, for a crime committed, rather than to award any form of compensation to an individual victim, for suffering caused.

Not sure how clear any of this is. I'm off to bed soonish, as am exhausted, but will check MN before collapsing onto my pillows, and will be back tomorrow. Feel free to ask if any of the above isn't clear, or if there's anything else you want me to ask DH.
67 is indeed a bit far from 84...
I'm really sorry you're having to go through this.
