The Battle of Redinha was a rearguard action which took place on March 12, 1811, during Masséna's retreat from Portugal, by a French division under Marshal Ney against a considerably larger Anglo-Portuguese force under Wellington. Challenging the Allies with only one or two divisions, Ney's 7,000 troops were pitched against 25,000 men. In a typical rearguard action, Ney delayed the Allied advance for a day and bought valuable time for the withdrawal of the main body of the French army.

Michel Ney, 1st Prince de la Moskowa, 1st Duke of Elchingen was a French military commander and Marshal of the Empire who fought in the French Revolutionary Wars and the Napoleonic Wars.
