2019 marked the 80th anniversary of the events on the Khalkhin-Gol River, during which Soviet troops defeated the Japanese army that invaded Mongolia. On this memorable date for Russian-Mongolian history, a detachment of volunteers organized a search expedition to places of military glory. Their goal was to perpetuate the memory of the fallen heroes-liberators and, along the way, tell the story of the events that happened through the prism of the artifacts found.
