The Romans promoted the use of a particular type of javelin called the 'pilum', or 'angon' as the Saxons would have called it. This type of spear is identified by it's longer iron shaft and barbed head. The idea was that the pilum would strike the target, ideally the shield, and lodge there. The barbs helped to lock it in position, and the thin iron shaft would buckle preventing the pilum from being thrown back should it be removed. However, the key part that it played was to weight down an opponents shield rendering it either useless or extremely difficult to wield. With his shield effectively down, he was then open to attack from other weapons. The significant thing about a javelin is that it didn't matter where it struck: in an opponent, in a shield or even in the ground causing people to lose their footing.
