Also known as 'Bain Tsagn', 'Bayantsagaan' or 'Baintsagn Hill'. High ground to the west of the Khalkhin Gol. Prewar, an obo (marker) was present at this location, Bain Tsagan Obo.
In 1939, the border between Mongolia and Manchuria was disputed, Mongolians claiming their border was east of Nomonhan, while the Japanese claimed it was along the Khalkhin Gol (Khalkhin River).
During the Battle of Khalkhin Gol / Nomonhan Incident July 1939, Japanese forces crossed a pontoon bridge they had established at Hara to cross into Outer Mongolia.
Although this offensive initially caught the Soviet forces by surprise, they responded with a force of tanks, armored cars and infantry to repell the Japanese, who eventually had to withdraw back across the river.
Yakovlev's Hero's Memorial
Replacing the Japanese memorial to the IJA war dead in 1954, the Mongolians had also put up a monument in honor of Soviet tank men – “Yakovlev’s heroes'.
