History of Guernsey St Saviour, St Pierre du Bois, Ste. Marie du Catel, and the Vale. The loss of Normandy by King John in 1204 isolated the Channel Islands from mainland Europe. Each time England and France went to war over the coming centuries, trade to and from the Channel Islands was restricted or banned and even when not officially at war, the island was repeatedly attacked by continental pirates and naval forces. Fortifications were improved in the Channel Islands, manned by professional soldiers and the Guernsey militia who would help to defend the Island for the next 600 years. Service was compulsory
History of Guernsey Lawgoch (remembered as "Yvon de Galles"), who was in the pay of the French king. Lawgoch and his dark-haired mercenaries were later absorbed into Guernsey legend as an invasion by fairies from across the sea. In 1394 Richard II of England granted a new Charter to the islands, because of great loyalty shown to the Crown, exemption for ever, from English tolls, customs and duties. Ship building skills improved and trade to and from Guernsey increased with a growing number of ports, sometimes using trading treaties and sometimes avoiding paying duties. Guernsey ships in the 14th century were small. 12-80
