Edward A. Freeman 
A short history of the Norman Conquest of England [EPUB ebook] 

The Norman Conquest (or the Conquest) was the 11th-century invasion and occupation of England by an army made up of thousands of Normans, Bretons, Flemish, and French troops, all led by the Duke of Normandy, later styled William the Conqueror.
William’s claim to the English throne derived from his familial relationship with the childless Anglo-Saxon king Edward the Confessor, who may have encouraged William’s hopes for the throne. Edward died in January 1066 and was succeeded by his brother-in-law Harold Godwinson. The Norwegian king Harald Hardrada invaded northern England in September 1066 and was victorious at the Battle of Fulford on 20 September, but Godwinson’s army defeated and killed Hardrada at the Battle of Stamford Bridge on 25 September. Three days later on 28 September, William’s invasion force of thousands of men and hundreds of ships landed at Pevensey in Sussex in southern England. Harold marched south to oppose him, leaving a significant portion of his army in the north. Harold’s army confronted William’s invaders on 14 October at the Battle of Hastings. William’s force defeated Harold, who was killed in the engagement, and William became king.
Edward Augustus Freeman (2 August 1823 – 16 March 1892) was an English historian, architectural artist, and Liberal politician during the late-19th-century heyday of Prime Minister of the United Kingdom William Gladstone, as well as a one-time candidate for Parliament. He held the position of Regius Professor of Modern History at Oxford, where he tutored Arthur Evans; later he and Evans were activists in the Balkan uprising of Bosnia and Herzegovina (1874–1878) against the Ottoman Empire. After the marriage of his daughter Margaret to Evans, he and Evans collaborated on the fourth volume of his History of Sicily. He was a prolific writer, publishing 239 distinct works. One of his best known is his magnum opus, The History of the Norman Conquest of England (published in 6 volumes, 1867–1879). Both he and Margaret died before Evans purchased the land from which he would excavate the Palace of Knossos.
