The Battle of Corunna, in Spain known as Battle of Elviña, took place on 16 January 1809, when a French corps under Marshal of the Empire Jean de Dieu Soult attacked a British army under Lieutenant-General Sir John Moore. The battle took place amidst the Peninsular War, which was a part of the wider Napoleonic Wars. It was a result of a French campaign, led by Napoleon, which had defeated the Spanish armies and caused the British army to withdraw to the coast following an unsuccessful attempt by Moore to attack Soult's corps and divert the French army.

Marshal of the Empire was a civil dignity during the First French Empire. It was created by Sénatus-consulte on 18 May 1804 and to a large extent reinstated the formerly abolished title of Marshal of France. According to the Sénatus-consulte, a Marshal was a grand officer of the Empire, entitled to a high-standing position at the court and to the presidency of an electoral college.
