The gathered host is numbered, once, where, as with Xerxes, counting was too difficult, by making each man as he passed put a pebble in a pile (which piles survive to mark the huge size of Frode’s army).  This is, of course, a folktale, explaining the pebble-hills and illustrating the belief in Frode’s power; but armies were mustered by such expedients of old.  Burton tells of an African army each man of whom presented an egg, as a token of his presence and a means of taking the number of the host.

We hear of men marching in light order without even scabbards, and getting over the ice in socks.

The war equipment and habits of the Irish, light armoured, clipped at back of head, hurling the javelin backwards in their feigned flight; of the Slavs, small blue targets and long swords; of the Finns, with their darts and skees, are given.

Watches are kept, and it is noted that “uht”, the early watch after midnight, is the worst to be attacked in (the duke’s two-o’clock-in-the-morning courage being needed, and the darkness and cold helping the enemy).

Spies were, of course, slain if discovered.  But we have instances of kings and heroes getting into foeman’s camps in disguise (cf. stories of Alfred and Anlaf).

The order of battle of Bravalla fight is given, and the ideal array of a host.  To Woden is ascribed the device of the boar’s head, hamalt fylking (the swine-head array of Manu’s Indian kings), the terrible column with wedge head which could cleave the stoutest line.

The host of Ring has men from Wener, Wermland, Gotaelf, Thotn, Wick, Thelemark, Throndham, Sogn, Firths, Fialer, Iceland; Sweden, Gislamark, Sigtun, Upsala, Pannonia.

The host of Harold had men from Iceland, the Danish provinces, Frisia, Lifland; Slavs, and men from Jom, Aland, and Sleswick.

The battle of Bravalla is said to have been won by the Gotland archers and the men of Throndham, and the Dales.  The death of Harald by treachery completed the defeat, which began when Ubbe fell (after he had broken the enemy’s van) riddled with arrows.

The defeated, unless they could fly, got little quarter.  One-fifth only of the population of a province are said to have survived an invasion.  After sea-battles (always necessarily more deadly) the corpses choke the harbours.  Seventy sea-kings are swept away in one sea-fight.  Heads seem to have been taken in some cases, but not as a regular Teutonic usage, and the practice, from its being attributed to ghosts and aliens, must have already been considered savage by Saxo, and probably by his informants and authorities.

Prisoners were slaves; they might be killed, put to cruel death, outraged, used as slaves, but the feeling in favour of mercy was growing, and the cruelty of Eormenric, who used tortures to his prisoners, of Rothe, who stripped his captives, and of Fro, who sent captive ladies to a brothel in insult, is regarded with dislike.
