This was before I realised putting everything on your SRT kit in your bag was a good idea. I lost my chest jammer in the long crawl and spent ages looking for it, by the time I got to the top of the 3rd pitch my cows tails were untying themselves and I was freezing so I thought retreat was the order of the day, I of course returned later on in my caving carrier and have since reached the sump at-least twice. The others got to the sump on this day.
