William the Conqueror
William began his plans for invasion almost as soon as he received news of the events in England. He called a meeting of his greatest men. William made plans to gather a large army from all over France. His influence and wealth meant he could mount a large campaign. His first task was to build a fleet of ships to carry his army across the English Channel. Then he started gathering an army. His friendship with Brittany, France, and Flanders  meant he did not have to rely only on his own army. He hired and paid soldiers from many parts of Europe. William asked for and got the support of the pope who gave him a banner to carry into battle. At the same time Duke William was planning his invasion, so too was Harold Hardrada. The king of England knew both would be coming but he kept his ships and forces in the south of England where William might land.
