Feudal organization spread cost and administration

William spread the cost of the expedition among nobles who had to build or obtain ships, equip their contingents, provide food, and manage their own administration. The result was a decentralized conglomerate following one ruler rather than a centrally managed standing navy. This structure explains the variation in ship types and captains across the force. Matilda of Flanders focused on William's personal safety by supplying the well-built Mora and a trusted navigator while she governed Normandy. Her contribution improved his chance of returning, while the leading nobles treated ships and troops as investments in the English lands they hoped to gain.
