The young Alexander conquered India.
Was he alone?
Caesar beat the Gauls.
Did he not have even a cook with him?
Philip of Spain wept when his armada
Went down. Was he the only one to weep?
Frederick the Second won the Seven Years' War.
Who else won it? 
(Bertholt Brecht, 1935)

In 2015 I was on an expedition with Hansjörg Auer, Alexander Blümel and Gerhard Fiegl. Our equipment, food and gear was carried by about fifty Sherpas to our basecamp. In only two days, each of them carried around 40 kilos to an altitude of 4.600 meters.
