I didn't suffer from that 20:20 vision I hasten to add as its possible to read your post Mark and think that you were referring to me. I just looked back and apart from one long post just giving my (mainly bad) experiences of the day (post #1635 here) the only comment I can see that I made about the guys getting befuddled and degrouping was this:
Hardly a battering eh?As for the staying together as a group it is worrying in those sort of conditions - one member is freezing, has shot legs and is lagging behind whilst the others are freezing while they wait. Doomed if you do and doomed if you don't almost. I don't think you should have lost sight of him though - he could have just wandered off and, well, died!.
