The Battle of Braga or Battle of Póvoa de Lanhoso or Battle of Carvalho d'Este saw an Imperial French corps led by Marshal Nicolas Soult attack a Portuguese army commanded by Baron Eben. When Soult's professional soldiers attacked, the Portuguese at first fought back but soon ran away. The French slaughtered large numbers of their opponents, who were mostly badly disciplined and poorly armed militia. The action was part of the second invasion of Portugal, during the Peninsular War.
