Just to give an example of what u/Epyr and u/DuxBelisarius said:

In popular perception the battle of Agincourt was won when French knights were mowed down by arrows of the English longbow before impaling themselves and their horses on sharpened wooden stakes. While these undoubtedly happened, most of the battle was actually a slugging match between English and French men-at-arms and dismounted knights in the mud.
