Question: Were rearguard actions common in this period? Passage:On 19 May 1804, Ney received his Marshal's baton, emblematic of his status as a Marshal of the Empire, the Napoleonic era's equivalent of Marshal of France. In the 1805 campaign, Ney took command of VI Corps of the Grande Armee and was praised for his conduct at Elchingen. In November 1805, Ney invaded the Tyrol, capturing Innsbruck from Archduke John. In the 1806 campaign, Ney fought at Jena and then occupied Erfurt. Later in the campaign, Ney successfully besieged Magdeburg. In the 1807 campaign, Ney arrived with reinforcements in time to save Napoleon from defeat at Eylau, although the battle ended in a draw. Later in the campaign, Ney fought at Guttstadt and commanded the right wing at Friedland. On 6June 1808, Ney was created Duke of Elchingen. In August 1808, he was sent to Spain in command of VI Corps and won a number of minor actions. In 1809, he routed an Anglo-Portuguese force under Sir Robert Wilson at Banos. In 1810, Ney joined Marshal Massena in the invasion of Portugal, where he took Ciudad Rodrigo from the Spanish and Almeida from the British and Portuguese, brusquely defeated a British force on the River Coa, and fought at Bussaco. During the retreat from Torres Vedras, Ney engaged Wellington's forces in a series of lauded rearguard actions (Pombal, Redinha, Casal Novo, Foz d'Arouce) through which he delayed the pursuing enemy forces long enough to allow the main French force to retreat unmolested. He was ultimately removed from his command for insubordination.
