In 1415, during the Hundred Years' War, Henry V invaded France to claim the throne. Dysentery-ravaged his army, but he pressed on. Reaching Agincourt (now Azincourt) on October 24, he faced a massive French force confident in their knightly prowess.[4][7]

The English were outnumbered 3:1 or more, with ~6,000-9,000 men mostly archers. French had 12,000-36,000, heavy on elite knights in gleaming plate armor weighing 50-60 lbs. Rain soaked the fields, creating a muddy trap.[5][6]

Henry positioned his army between woods, limiting French flanks. Longbowmen formed the core, stakes protecting them from cavalry.[8]

The English longbow, made of yew, stood 6 feet tall and drew 100-180 lbs. Trained from childhood, yeomen fired 10-12 arrows/minute up to 300 yards, with bodkin points designed to punch through mail and early plate.[5][9]

French crossbows were slower (2 arrows/min) and shorter-range. Dismissing longbows as peasant weapons, French knights planned a glorious charge.[4]

Volleys darkened the sky: First at 300 yards halted advances; closer shots felled horses and pierced visors, gaps in armor.[7]

Dawn broke October 25; French delayed, letting English rest. When knights charged, mud bogged them down. Armored men sank to knees, exhausted before reaching lines.[6][8]

Longbows shredded the advance: Thousands fell in 'arrow storms.' Surviving knights piled in dead zones, trampling comrades. English men-at-arms finished them in melee.[9]

Henry ordered no quarter; French losses catastrophic, including dukes and counts. English victory total despite odds.[4]

The win revived English fortunes in the war, leading to Treaty of Troyes naming Henry heir to France. Symbolized commoner's might over nobility.[7]

Shakespeare immortalized it: 'We few, we happy few, we band of brothers.' Modern reenactments and tests validate the longbow's role.[5]

Lessons endure: Technology, terrain, and tactics trump numbers. Agincourt marked the longbow's peak and knights' decline.[8]

⚠ī¸Things to Note

  • Estimates vary due to medieval records; French numbers debated as high as 36,000.
  • Henry V banned looting to maintain discipline amid victory.
  • Many French nobles died due to chivalric tradition of leading charges.
  • Modern tests confirm longbows could penetrate armor at 200+ yards.
