Overview

The Battle of Braga or Battle of Póvoa de Lanhoso or Battle of Carvalho d'Este saw an Imperial French corps led by Marshal Jean-de-Dieu 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.

Significance

The Battle of Braga was a decisive engagement during the French second invasion of Portugal in the Peninsular War. Soult's corps, numbering around 16,000 troops, routed a Portuguese force of up to 25,000 under Baron Eben, inflicting roughly 4,400 casualties. The collapse of the Portuguese resistance at Braga exposed the weakness of relying on ill-disciplined and poorly armed militia against a professional imperial army, leaving the road into Portugal significantly more open to French advance. The scale of the defeat underscored the difficulty Portugal faced in mounting effective conventional resistance without substantial regular-force support.

Tactics

When Soult's professional soldiers attacked, the Portuguese initially offered resistance but quickly broke and fled. The French then slaughtered large numbers of the retreating force, most of whom were poorly disciplined and inadequately armed militia.
