Immediatley assume the worse and apply a torniquet using the laces from the other shoe, and try to extract the leg. The bones protruding and i'm bleeding heavily, Its dusk and beginning to rain, so no one vill even be in the vicinity even with luck before 8.00am. As my favourite bushcraft location is up on the moors with no trees present, I remove the aluminium says from my rucksack and splint my leg. I put on the waterproof i have with me, aloing with warm clothes.first aid kit and any thing i have to deal with the injury i take and put all the useful food i have into the bag after emptying it, and any other useful stuff i have with me, stove for a hot drink, tarp or section of flysheet, some pegs cup water possibles pouch etc, put the bag on the front and start scooting out on my bum. I go out the way i came in as i know the area roughly and i remember a dwelling about 3miles back. The torniquet is safe for 3 hours but i may have to release it occasionally if im not going to make it in that time.
