DR GILDENHUYS
Purely guessing, and let me underline it's guessing, I think that everybody just forgot about that gap, they deployed the soldiers, when the marchers saw the opening I think they thought here's our chance and in all probability on the spur of the moment they decided to enter into, rather to go through the gap and enter into the Ciskei.  It's my personal opinion, I'm not basing it on anything.  I've heard about the trap theory, I can't say whether it's correct or not.
