Can someone clarify a few points for me please.
'Marches' - is a march always a days journey? Presumably calculated according to the expected terrain?
Lieues - i've forgotten how many miles to the Lieue , not quite the same as a league I think.
"18 lieues de poste de Vienna' - what does that mean?
What is a 'mille' - in miles please, kilometres still confuse me.
And on a smaller scale, I know 'pieds' and 'pouces' are not exactly the same as 'feet' and 'inches' (I have found a conversion site) but are there 12 pouces to the pied?
