Significance

The Battle of Grijó resulted in a victory for the Anglo-Portuguese Army under Wellesley over Soult's French forces during the Second French invasion of Portugal. With a numerical advantage of roughly 18,000 against 7,000, Wellesley inflicted approximately 200 French casualties while sustaining 104 of his own. The engagement proved immediately consequential: the following day, Wellesley drove Soult from Porto in the Second Battle of Porto, making Grijó a direct operational precursor to the recapture of that city. Together, the two engagements effectively ended the Second French invasion of Portugal.
