16. Charles d’Albret
As Constable of France, Charles d’Albret’s leadership at the Battle of Agincourt is often cited for its disastrous outcome. Facing the English forces led by Henry V, d’Albret’s decisions were marred by overconfidence and tactical rigidity. The French, hampered by heavy armor and poor terrain, launched direct assaults into narrow, muddy fields, where they were decimated by English longbowmen. His failure to adapt to battlefield conditions and heed strategic advice resulted in a catastrophic defeat, significantly weakening French military strength and altering the course of the Hundred Years’ War.
