🐉 A war of mobility

Vikings strike fast, move along rivers, and choose rich targets (towns, abbeys). Fighting them requires:

• gathering forces quickly;
• coordinating counts and bishops;
• obtaining a “clear” battle before the enemy disperses.

👑 A victory that serves authority

For a young king like Louis III, a victory is also a political tool: it strengthens authority, eases alliances with great men, and provides a shared narrative for the kingdom.
