Could an arrow fired from an english longbow penetrate gothic armour?
Actually there was quite variety of arrowheads available to the English longbowmen from horse killing to armor piercing arrowheads. Yes, the longbow could most definitely pierce armor. I don’t know about this goth stuff, the so-called gothic period was years after Agincourt. Almost 500 years! By Goth I assume you mean the romantic gothic era that goths love. The time of Mary Shelley or about 1830. 1/3 of the French nobility (wearing armor) were killed the first day of the battle of Crecy by longbows. An armor piercing arrowhead was about 5 inches long and was almost a rod with a chiseled point.
