Q: Question: Of Sluyter's interests, when did the event which led to America being populated by Europeans occur? Passage:Andrew Sluyter is an American social scientist who currently teaches as a professor in the Geography and Anthropology Department of the Louisiana State University in Baton Rouge. His interests are the environmental history and historical, cultural, and political ecology of the colonization of the Americas. He has made various contributions to the theorization of colonialism and landscape, the critique of neo-environmental determinism, to understanding pre-colonial and colonial agriculture and environmental change in Mexico, to revealing African contributions to establishing cattle ranching in the Americas, and to the historical geographies of Hispanics and Latinos in New Orleans. With the publication of Black Ranching Frontiers: African Cattle Herders of the Atlantic World, 1500–1900 (Yale University Press, 2012) and a 2012–13 Digital Innovation Fellowship from the American Council of Learned Societies, he has joined a growing number of scholars from multiple disciplines working from the perspective of Atlantic History and using the tools of the Digital Humanities. His latest book, Hispanic and Latino New Orleans: Immigration and Identity since the Eighteenth Century (LSU Press, 2015), co-authored with Case Watkins, James Chaney, and Annie M. Gibson, was awarded the 2015 John Brinckerhoff Jackson Book Prize by the American Association of Geographers.

Q: 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 Armée 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 Güttstadt 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 Baños. In 1810, Ney joined Marshal Masséna 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 Côa, 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.
