I have listened to Zack's podcast on discipline and conduct of British troops in the Peninsular campaigns and I am mindful of the events surrounding Cuidad Rodrigo and Badajoz. I'm also of the understanding that Spanish troops were not encouraged to continue with Wellington's army deeper into French territory from 1814 at least in part due to concerns of reprisals. Very little I have speaks to the conduct of Portuguese troops in either Spanish or French territory. It seems clear that their alliance with Spain was an unnatural one born of circumstances just as that of the British with the Spanish. Like the Spanish over the French occupation, the Portuguese had much to be bitter about. How does their record compare to either of their allies?
