One of the big shockers with the Galatians was that they didn't seek truce in battle to collect the bodies of their dead, or so claimed Pausanias. The Romans had a similar practice to the Galatians, though. The Greeks, perturbed as they were by the Galatian indifference to the intermingled and exposed dead, usually sought to give them burial. So its also notable the few times they either were not allowed to retrieve their dead, or no one came along to do so (I'm trying to remember the battle, but there is a battle where ~6,000 are killed, the dead aren't retrieved, and Polybius or Plutarch--or maybe someone else--mentions that people still find bones and equipment turning up there).
