When banners are called for war, friends follow friends, brothers follow brothers, and sons follow fathers. Armed with only the most rudimentary equipment (from a stolen kitchen knife to a sharpened hoe to a stick with a rock tied to the end), they fight a thankless battle against disease and armored knights until one day they break. Sometimes they break in their first battle, sometimes in their hundredth. Watching their friends die, or perhaps entering the service of an unfamiliar lord when their original liege dies, the broken man runs away in the heat of battle or sneaks off in the dead of night. Having become accustomed to living off the land of the smallfolk where the war is being fought, it is a small adjustment for the broken man to begin stealing their daughters, or killing for what he likes. Often, without really knowing where he is or how to get back to his village, the broken man forgets all thought of home and simply becomes a bandit. Although bands of broken men are liable to form in any extended campaign, they tend not to survive the peace, as local lords ride home to bring peace to their lands.
A Feast for Crows
In the aftermath of the Red Wedding and the raid on Saltpans, some broken men who stay at the inn are hanged with salt in their mouths by the brotherhood without banners, despite believing they had been under the protection of guest right.
