One of the most well known yet still much unknown warriors of ancient times are the Berserkers (Berserkr) of the Viking Age. These fierce warriors said to go into an animalistic rage and even trance like in ferocity would bang their axes against their shields and would even chew on their shields whilst gnashing their teeth. They are mentioned in the Sagas and even an account of one famous Berserker who held off an army at the Battle of Stamford Bridge. So let us now dive into the what is known and what is thought of these ancient Special Ops warriors of the North.
Hrolf’s Saga tells of the hero Bjarki, who takes on the shape of a bear in battle:
Men saw that a great bear went before King Hrolf’s men, keeping always near the king. He slew more men with his forepaws than any five of the king’s champions. Blades and weapons glanced off him, and he brought down both men and horses in King Hjorvard’s forces, and everything which came in his path he crushed to death with his teeth, so that panic and terror swept through King Hjorvard’s army…” (Gwyn Jones. Eirik the Red and Other Icelandic Sagas. NY: Oxford Univ. Press. 1961. p. 313).
Another Óðinnic quality possessed by the berserk is a magical immunity to weapons. In Havamál, Óðinn speaks of spells used to induce this immunity:
A third song I know, if sore need should come
of a spell to stay my foes;
When I sing that song, which shall blunt their swords,
nor their weapons nor staves can wound
An eleventh I know, if haply I lead
my old comrades out to war,
I sing ‘neath the shields, and they fare forth mightily;
safe into battle,
safe out of battle,
and safe return from the strife.
(Lee M. Hollander, trans. Poetic Edda. Austin.
Univ. of Texas Press. 1962. pp. 44-45)
The berserk was sometimes inherently possessed of this immunity, or performed spells to induce it, or even had special powers to blunt weapons by his gaze. Many tales say of their berserkers, “no weapon could bite them” or “iron could not bite into him.” This immunity to weapons may also have been connected with the animal-skin garments worn by the berserk. As we saw above, while in animal form, “blades and weapons glanced off” Bodvar Bjarki. Similarly, Vatnsdæla Saga says that “those berserks who were called ulfhednar had wolf shirts for mail-coats” (Ellis-Davidson, “Shape Changing,” p. 133). This concept of immunity may have evolved from the berserker’s rage, during which the berserk might receive wounds, but due to his state of frenzy take no note of them until the madness passed from him. A warrior who continued fighting while bearing mortal wounds would surely have been a terrifying opponent. SOURCE
