Celts were typically taller than Romans and used longer swords, yet the Romans almost always won. Tall Celt swings long sword. Roman catches it on shield and stabs up into Celts belly and chest, rips blade off to the side as he withdraws and eviscerates Celt. Plan B was to reach behind the Celt's leg and hamstring him.
Weren't the reasons why the Celts lost to Romans (1) numbers (2) battle coordination and (3) Celt allies?
