PGHM Chamonix: history, selection and rescuer equipment

The Peloton de Gendarmerie de Haute Montagne (PGHM) of Chamonix is a national gendarmerie unit specialized in mountain rescue, based in Chamonix-Mont-Blanc. Every rescuer is both a gendarme and holds a civilian high-mountain qualification (UIAGM guide, ski instructor or ski patroller) — a dual skill set that makes it an international reference in alpine rescue.

On December 22, 1956, mountaineers Jean Vincendon and François Henry began a winter attempt on Mont Blanc despite an unfavorable opinion from the guides' bureau. Four days later, the alarm was raised over their disappearance; the lack of an organized rescue structure delayed the response, and both men died on the Italian side. This tragedy, which shook the alpine world, pushed the authorities to structure mountain rescue: a circular dated August 21, 1958 required prefects to organize it, and the Groupe Spécialisé de Haute Montagne — nicknamed the "Brigade Blanche" — was created on November 1, 1958 in Chamonix, the first gendarmerie unit of its kind. It became the Peloton Spécialisé de Haute Montagne, then the Peloton de Gendarmerie de Haute Montagne in the early 1970s, once the unit gained full operational autonomy. Its 60th anniversary was celebrated in 2018, alongside the 30th anniversary of CNISAG (the gendarmerie's national ski and mountaineering training center).

To join the PGHM, candidates must first be gendarmes, then pass selection tests close to those of a high-mountain guide. A complete 4-to-5-year training program follows, covering three areas: rescue techniques themselves (rope, helicopter, climbing, glacier, water environments), judicial and police training, and civilian mountain qualifications (high-mountain guide, ski instructor or ski patroller). This long path explains the rarity of the profile and the unit's reputation for excellence.

The Chamonix unit has around 40 rescuers, making it the largest of twenty PGHM and PGM (Peloton de Gendarmerie de Montagne) units across France, which total roughly 300 personnel. In the field, an operation systematically mobilizes a pair of rescuers, a doctor and a helicopter crew (pilot and winch operator/mechanic); tactical choices are often decided in flight, by consensus. Two helicopters alternate over the massif on a weekly rotation: Choucas 74, the national gendarmerie's blue aircraft, and Dragon 74, the red-and-yellow Sécurité Civile aircraft that covers the Mont Blanc massif in particular. The PGHM has also structured psychological support — systematic debriefing after each operation, access to psychologists — for professionals regularly confronted with traumatic situations.

PGHM Chamonix records an average of 20 to 30 deaths and over 100 accidents per year on the Mont Blanc massif. According to the national gendarmerie, the unit's rescuer-gendarmes carry out between 800 and 1,000 sorties per year. These figures vary significantly with weather conditions and summer crowding, with the normal Goûter route concentrating a large share of interventions.

PGHM's technical equipment covers rope rescue, helicopter winching, glacier travel and field medicalization — gear specific to the unit's public-service missions, distinct from each rescuer's personal clothing. On a personal level, two PGHM Chamonix rescuers, Fred Souchon and Bastien Fleury, are individual mountain ambassadors for the French outfitter Cimalp, whose trousers include Cordura-reinforced panels and whose jackets use a waterproof-breathable Ultrashell membrane with Kevlar-reinforced wear zones. This is not an official supply arrangement for the unit, but a personal choice made by two of its members.
