Throughout the long five hundred years of war between Scottish and English kings, the Scots tended to win the wars but lose the big battles. Scotland was a smaller and poorer kingdom, and the way of fighting battles that the Scots were good at (lining up big masses of spearmen and axemen with jacks and steel caps) was not very effective against the way that the English were good at (dismounting their armed men and galling the enemy with arrows until they charged, breaking formation as they came because no prince in Europe could keep a large army together long enough to drill it). A fourteen-line gem of a poem describes the way of fighting which proved most successful in campaign after campaign:
On fur suld be all Scottis weire, // weire = Wehr, defense
By hyll and mosse themself to reare. // reare: roar? an earlier edition has weire “defend”
Lat woods for wallis be bow and speire,
That innymeis do them na deire.
In strait placis gar keep all store,
And byrnen ye planeland thaim before.
Thane sall thai pass away in haist
Wenn that thai find na thing but waist.
With wykes and waykings of the nyght // wyke: wake
And mekill noyis maid on hytht, // mekill: big, large
Thaime sall ye turnen with gret affrai, // affray: fright, alarm
As thai ware chassit with swerd away.
This is the counsall and intent
Of gud King Robert’s testiment.

Now roll that around in your mouth a bit and savour it. Enjoy the language and the rhythm and the joy with which it describes something horrible in ways that poor crofters and shepherds can understand. Think about how rare it is to have something like this from the side which was wise to avoid battle. And then if you really must, go on where I ask my annoying academic question, namely where does this poem come from?
