TheSvinfylking (Old Norse for "swine array" or "boar snout"),[1] was a formation used in battle. Related to thewedge formation, it was used inIron Age Scandinavia and later by theVikings.[2] It was also used byGermanic peoples during theGermanic Iron Age and was known as theSchweinskopf or "swine's head".[3] Its invention was attributed to the godOdin.[3][4]
The apex was composed of a single file. The number of warriors then increases by a constant in each rank back to its base. Families and tribesmen were ranked side by side, which added morale cohesion.[5][3] The tactic was admirable for an advance against a line or even acolumn, but it was poor in the event of aretreat.[3]
The formation consisted of heavily armed, presumably hand-to-hand,warriors and less-armoredarchers grouped in a triangle formation with the warriors in the front lines protecting the archers in center or rear.Cavalry charging a group in Svinfylking formation were frequently attacked by the outer warriors with spears, which caused complete chaos for the horses. The Svinfylking could also be used as a wedge to break through enemy lines. Several Svinfylking formations could be grouped side by side and appear something like a zig-zag to press or break the opposition's ranks. Its weakness was its inability to handle flanking. The Svinfylking was based on a monumental shock, and unless it broke the enemy lines immediately, its warriors would not hold long.[6][unreliable source?][citation needed]
