The Captain Alatriste serie? Incidentally the novel Sun of Breda is the only Alatriste novel that is translated into Dutch.
Yes, it was one of Perez Reverte's Alatriste novels, but I do not remember wich -probably Sun of Breda, as it happened in a siege, but since the poor man never gets a moment's peace it could have been anywere.
If you rememebr the scene too, then that's where it was.
Mmmm. All this talk of spanish tercios has made me nostalgic. It may be time to re-read the series.
