Invasion of Russia
George's historical writing and teaching were largely concerned with military history (in which he was a pioneer at Oxford) and with the relationship between history and geography. His main publications were "Battles of English History" (1895), "Napoleon's Invasion of Russia" (1899), "Relations of Geography and History" (1901; 4th edit. 1910), and "Historical Evidence" (1909). He also compiled "Genealogical Tables illustrative of Modern History" (1874; 4th edit. 1904) and "Historical Geography of the British Empire" (1904; 4th edit. 1909).
