Where 1415 fits
Why 1415 is special
An English army, outnumbered and weakened by dysentery, defeated a much larger French force in mud that neutralised heavy cavalry. The longbow's role is real but routinely overstated; terrain and French crowding did much of the work.

History
Agincourt is remembered as a longbow victory, and the archers mattered — but a narrow muddy field that funnelled and bogged down heavily armoured French cavalry mattered at least as much. The battle changed little strategically and a great deal reputationally.
