in the
Swiss Alps; its height is At the beginning of 1865, the
Matterhorn was still unconquered, and more than one assault on it was planned. One such group consisted of Douglas,
Edward Whymper, and their guide
Peter Taugwalder. Whymper had already made several unsuccessful attempts on the mountain. On 5 July, this group made the second ascent (and the first by the north-north-west ridge) of the
Ober Gabelhorn, a peak of 4,053 metres on the north-west side of the Matterhorn; Hearing of a planned assault on the main peak by an Italian party, Douglas and Whymper joined forces with two other British climbers,
Charles Hudson and
Douglas Robert Hadow, and their guide
Michel Croz. At 4:30 a.m. on 13 July, a combined party of seven men, led by Whymper, set off for the Matterhorn under a clear sky: Whymper, Douglas, Hudson and Hadow, plus Taugwalder and son, and Croz. They climbed past the
Schwarzsee to a plateau where they camped. Meanwhile, the Italians, led by Carrel, had camped at a height of about 4000 meters on the Lion Ridge. On 14 July, Whymper's party proceeded to a successful
first ascent by the Hörnli route. However, on the way down, Hadow fell, knocking down Croz, and also dragging Hudson and Douglas, connected by a rope. The four fell to their deaths on the
Matterhorn Glacier 1,400 metres below. Three of the bodies lost were later found, but not Douglas'. The rival party of Italian alpinists reached the Matterhorn's summit three days later. ==Aftermath==
