But it was not so on the Continent. The Norman barons as a body had at first refused to support the duke in an invasion of England, but as individuals they had been brought round to join in William's project, and to give far more aid in ships and men than they were bound to do by their feudal engagements. Having accomplished this, William issued an invitation to all adventurous spirits in Europe to join him in his crusade against the excommunicated King of England, promising that all should share alike in the plunder of England and in the division of its land. The bait was a tempting one. Some joined the enterprise merely for the sake of gaining glory under the banner of one who was regarded as the greatest military leader in Europe, others were influenced by love of gain, while, as in the crusades, numbers joined to obtain absolution for past misdeeds by taking part in an enterprise blessed by the Pope. Thus the force which William was collecting greatly exceeded that which the resources of Normandy alone could have set on foot.
