La difesa dei territori dell’Ossola, sul corridoio spagnolo delle Fiandre, negli ultimi decenni del secolo XVII

The Ossola territories, in the area to the northwest of Milan, have constituted the western border most in contact with the nordic and tens-alpine world, ever since the first establishment of the Duchy of Milan. It is already known from G. Parker’s monography on the camino español that one of the common routes, which allowed overland redeployment of Spanish troops headed towards Flanders, from the Liguria region across central Europe, would go through Ossola and cross the Simplon Pass or the Gries Pass.
