[6] He was the first climber in the world who climbed an eight-thousander in the alpine style in winter, for which he was nominated for the Piolet d'Or award.
[7] On 25 January 2018, while attempting his seventh try at a winter ascent of Nanga Parbat, known as the "Killer Mountain", in Pakistan,[8] at 8,126 m (26,660 ft), Mackiewicz had reached the summit[citation needed] from the Diamer side along with French climber Élisabeth Revol.
On 27 January 2018 the rescue team, including Denis Urubko and Adam Bielecki, were dropped off by a helicopter at 4,900 m (16,100 ft) on the mountain.
Mackiewicz, who was believed to be in his tent at around 7,400 m (24,300 ft), could not be rescued due to bad weather and a snowstorm.
Ludovic Giambiasi, Revol's partner, wrote on a Facebook post: The rescue for Tomasz is unfortunately not possible – because of the weather and altitude it would put the life of rescuers in extreme danger, It's a terrible and painful decision.
