Irving continued to climb with Mallory after the latter had left Winchester; in 1911 Irving led Mallory and another of his ex-pupils, Harry Tyndale, on the third ascent of the Kuffner (or Frontier) ridge on Mont Maudit. According to Helmut Dumler, Mallory was apparently prompted by the death of friends on the Western Front in 1916 [to write] a highly emotional article of his ascent of this great climb; this article was published as 'Mont Blanc from the Col du Géant by the Eastern Buttress of Mont Blanc' in the Alpine Journal.
