Well, I'd guess I understand about 60% of what I write. BTW, from what Rob (and my wife !) say, it's much worse in person.
and now I have an explanation (subject to confirmation through intense historical research accompanied by pallets of high-test beer) for the outcome at the Windmill.

Your ancestor was designated PsyOps officer (with a voice of 10, nay 100 men) - and made his pitch to the Languedoc grenadiers. Not only did they not understand a word he said, his presentation put the rest of Murray's Highlanders to sleep. And, the rest is history as they say.
