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.
