https://en.wikipedia.org/wiki/SchiltronSo in reality the Scots used a spear phalanx formation (this was depicted like once in the entire movie), which was good against cavalry and infantry, but they had no shields (or small shields) so archers just shot into them (this was a recurring issue…)
It seems like this would have worked if they just used large shields which easily block arrows.
The Welsh tried the same retarded shit and got btfo by English archers too.
Phalanx formations weren't new, people in the fucking bronze age figured out to use shields with them though.
