Winston Churchill, in A History of the English-Speaking Peoples, wrote that Port was a pirate who founded Portsmouth in 501. England's southern coast was vulnerable to Danish Viking invasions during the eighth and ninth centuries, and was conquered by Danish pirates in 787. In 838, during the reign of Æthelwulf, King of Wessex, a Danish fleet landed between Portsmouth and Southampton and plundered the region. Æthelwulf sent Wulfherd and the governor of Dorsetshire to confront the Danes at Portsmouth, where most of their ships were docked. Although the Danes were driven off, Wulfherd was killed. The Danes returned in 1001 and pillaged Portsmouth and the surrounding area, threatening the English with extinction. They were massacred by the English survivors the following year; rebuilding began, although the town experienced further attacks until 1066. Norman to Tudor Although Portsmouth was not mentioned in the 1086 Domesday Book, Bocheland (Buckland), Copenore (Copnor), and Frodentone (Fratton) were. According to some sources, it was founded in 1180 by the Anglo-Norman merchant Jean de Gisors. King Henry II died in 1189; his son, Richard I (who had spent most of his life in France), arrived in Portsmouth en route to his coronation in London. When Richard returned from captivity in Austria in May 1194, he summoned an army and a fleet of 100 ships to the port. Richard gave Portsmouth market-town status with a royal charter on 2 May, authorising an annual fifteen-day free-market fair, weekly markets and a local court to deal with minor matters, and exempted its inhabitants from an £18 annual tax. He granted the town the coat of arms of Isaac Komnenos of Cyprus, whom he had defeated during the Third Crusade in 1191: "a crescent of gold on a shade of azure, with a blazing star of eight points", reflecting significant involvement of local soldiers, sailors, and vessels in the holy war. The 1194 royal charter's 800th anniversary was celebrated in 1994 with ceremonies at the city museum. King John reaffirmed RichardI's rights and privileges, and established a permanent naval base. The first docks were begun by William of Wrotham in 1212, and John summoned his earls, barons, and military advisers to plan an invasion of Normandy. In 1229, declaring war against France, HenryIII assembled a force described by historian Lake Allen as "one of the finest armies that had ever been raised in England". The invasion stalled, and returned from
