"It was too late to take risks now. I asked Tenzing to belay me strongly, and I started cutting a cautious line of steps up the ridge. Peering from side to side and thrusting with my ice axe, I tried to discover a possible cornice, but everything seemed solid and firm. I waved Tenzing up to me. A few more whacks of the ice–ax, a few very weary steps, and we were on the summit of Everest. It was 11:30 AM. My first sensation was one of relief — relief that the long grind was over, that the summit had been reached before our oxygen supplies had dropped to a critical level; and relief that in the end the mountain had been kind to us in having a pleasantly rounded cone for its summit instead of a fearsome and unapproachable cornice. But mixed with the relief was a vague sense of astonishment that I should have been the lucky one to attain the ambition of so many brave and determined climbers. I seemed difficult to grasp that we'd got there. I was too tired and too conscious of the long way down to safety really to feel any great elation. But as the fact of our success thrust itself more clearly into my mind, I felt a quiet glow of satisfaction spread through my body — a satisfaction less vociferous but more powerful than I had ever felt on a mountain top before. I turned and looked at Tenzing. Even beneath his oxygen mask and the icicles hanging form his hair, I could see his infectious grin of sheer delight. I held out my hand, and in silence we shook in good Anglo-Saxon fashion. But this was not enough for Tenzing, and impulsively he threw his arm around my shoulders and we thumped each other on the back in mutual congratulations."
