Thousands of people across Turkey defied freezing weather Sunday to march in commemoration of the soldiers fallen in the Sarıkamış Campaign of World War I, a catastrophic chapter in Turkish history that also changed the fate of a nation.

People in every city marched in a re-enactment of the campaign where more than 90,000 soldiers froze to death in Sarıkamış in eastern Turkey. The largest march was in Sarıkamış, now a small town in Kars province. A crowd, including citizens and activists from various nonprofit organizations, stood in front of a large ice statue in the form of Ottoman soldiers throughout Saturday night. Later, about 20,000 people of all ages, including three cabinet ministers, marched to the Allahüekber Mountains where Ottoman troops succumbed to the biting cold during the campaign between Dec. 22, 1914 and Jan. 15, 1915. Bearing Turkish flags, the crowd started the march Sunday morning, chanting patriotic slogans amid snowfall.

Flanked by commandos of the Turkish Army dressed in white uniforms, they walked a 6.5 kilometer-long route at a height of 2,800 meters before reaching ceremonial ground to mark the end of the march. The route was where the soldiers are believed to have frozen to death in the cold weather. The ceremony ground was the spot on the summit of the Allahüekber Mountains that was the sole obstacle before the Ottoman troops commanded by Enver Pasha 104 years ago. Participants in the march recited passages from the Quran in memory of the fallen soldiers.

Turkey's Interior Minister Süleyman Soylu, Youth and Sports Minister Mehmet Muharrem Kasapoğlu and Minister of Industry and Technology Mustafa Varank joined the march.

Large-scale commemoration ceremonies have been held in Sarıkamış every year since 2003 when it was confined only to a small group of climbers and activists.

Several other large marches were held across Turkey — from Trabzon to Antalya, from Mount Erciyes in Kayseri to Izmir.

The Sarıkamış offensive undertaken by the Ottoman high command was the first military operation of the empire in World War I. The offensive that began late in December 1914 in the dead of winter quickly succumbed to adverse weather conditions, with units lost in a blizzard. Only a few units reached the destination of Sarıkamış, which was under Russian occupation at the time, and were repelled. Most of the troops froze to death before they even reached the Russian lines. Despite the Ottoman defeat, the Russian command was alarmed enough to call for help from its allies, which initiated the famous Gallipoli campaign where Ottoman forces emerged victorious.
