Something from a wargamer called Besilarius on another site I go too...... Don't know if this is accurate given the accounts given in other text.....
An early book by George McDonald Frasier (editor of the Flashman papers) was on the raiding that took place along the English Scottish border. Its title was The Steel Bonnets.
There were no illustrations that I recall, but he quoted various accounts that described the reivers.
The thing was that these were not organized forces, so they had no uniforms or equipment. Everyone came as they were. (Something like the farmers at Lexington and Concord.) Just about any possible look occurred.
Typical was a helmet (or bonnet), sword, dirk, targe (small shield), a lance, and a leather vest (if they were lucky). These reivers relied on speed and surprise.
The lance was just as useful in driving cattle (much like any subsistence farmers, cattle was wealth). Since there was no drill or training for combat, it is probable the lance was more for show in a confrontation than actual combat use.
These riders should be treated as irregular raiders, not real combat troops.
Something along the lines of Bash-Bazooks or native Americans.
