Battle of Agincourt: English victory over French forces

On October 25, 1415, during the Hundred Years' War, King Henry V led a significantly smaller English army to a decisive victory against a much larger French force at Agincourt. While the French army numbered between 20,000 and 30,000, the English force consisted of approximately 6,000 fighters, including 5,000 longbowmen.

The English victory was driven by the tactical use of the longbow and the exploitation of the terrain. Heavy French cavalry struggled in the narrow, muddy battlefield, which neutralized their armored advantage and led to chaos and high casualties. The French suffered over 6,000 deaths, whereas English losses were minimal, with fewer than 450 dead.

This victory had major political consequences, including the Treaty of Troyes in 1420, which named Henry V as the heir to the French throne. However, English dominance in France was eventually halted by French successes led by Joan of Arc.
