At Agincourt the prisoners that were executed were all noblemen or landed knights. The custom was for these prisoners to be taken, because they could be ransomed back to their wealthy families. It was a shocking event because it broke the conventions of the times. It would have been very unlikely that common men would have ever been taken prisoner. They'd have just been slaughtered on the battlefield, if they did not run away.
