The Lances fournies (French: "lances furnished") was a medieval equivalent to the modern army squad that would have accompanied and supported a man-at-arms (a heavily-armoured horseman popularly known as the "knight") in battle. These units formed companies under a captain either as mercenary bands or in the retinue of wealthy nobles and royalty. Each lance was supposed to include a mixture of troop types (the men-at-arms themselves, lighter cavalry, infantry, and even noncombatant pages) that would have guaranteed a desirable balance between the various components of the company at large; however, it is often difficult to determine the exact composition of the lance in any given company as the available sources are few and often centuries apart.
