- Lack of strategic planning: Joan of Arc was known for her bravery and determination on the battlefield, but she sometimes lacked strategic planning. For instance, at the Battle of Patay in 1429, she pursued the retreating English forces too far, which resulted in heavy French losses.
- Underestimating the enemy: Joan of Arc's confidence and faith in her divine mission sometimes led her to underestimate the strength and tactics of the enemy. This was evident during the siege of La Charite in 1429, where she suffered a defeat due to her miscalculation of the enemy's defenses.
- Impatience: Joan of Arc could be impatient at times, which occasionally led to rash decisions. For example, at the Battle of Compiegne in 1430, she insisted on leading a cavalry charge across a bridge, which resulted in her capture by the Burgundians.
- Political naivety: Joan of Arc's military successes brought her fame and influence, but she lacked political experience and finesse. This sometimes made it difficult for her to navigate the complex power struggles and diplomacy of the time.
It's important to note that Joan of Arc was a young and inexperienced military leader, and her mistakes should be considered in the context of the challenging circumstances and the overall impact she had on the war.
