I do see where my mistake was here and my ignorance was sort of awkwardly positioned. I was aware of the Prussian Austrian front, and had the impression that that was the start. The years given for the war here seem to coincide with that don't, but wars start before official dates. That's not a good reason at all, in fact the separate page for the French and Indian War give the earlier year. It's a poor excuse for my ignorance. In these wars within wars some people, myself as well, can get confused.
