We had been in the national park for most of a fortnight, somewhere between Thames and the coastline. We jog trotted the single tracks all day numbering off from one to seventeen over and over so as to know no one had been left behind. The PTI's, the physical training instructors, would come and go amongst us, encouraging, admonishing, gesticulating, constantly pushing us on in a straight line which probably doubled back on the line we had followed the day before.
I was at the front, I spent most of the time up there as platoon leader. The voices were trailing away back to number seventeen again, some guys took the time to put on a silly voice, most just got it over and done with.
The PTI was suddenly there in front of me, coming fast back along the track so that I stepped short for a moment. He came right up and then eased by, passing along down the line with the thick bush straining against his thick legs, all the time he was saying 'just keep going, just keep going...'.
I ran on, called 'one', and the voices came again in their slowly weakening train.
Maybe a couple of hundred metres on the path opened slightly, the ground under our feet carpeted in spindly grass which caught the sunlight as the canopy above opened. I was running straight up to a rocky edge, with a view of the river stretching out below. I must have hesitated for a moment and he was there at my shoulder, the PTI moving fast so that he came past me, looked back and said 'just keep going' as he opened his arm out towards the space beyond the edge.
I just kept going. We were wearing boots and carrying heavy backpacks. I remember hitting the water because it was the first time I had ever gone under and not started to rise, so that I had to really kick my legs to begin up towards the light. I came and saw him up there, his big hand on the chest of number two, holding back the train. He waved his arm again, get out of the way, so that I pushed myself towards the bank, and number two came down to explode against the dark green water.
