and 359 Orqon soldiers) were selected and stationed in Hulunbuir mostly from non Muren area. After 2000 soldiers were forced to join Dzungar-Qing wars in 1733, mostly Barga soldiers were left to protect this area. They became "Old Barga", since they arrived before New Barga. Relocation - New Barga ("Shine Barga" in Mongolian) In order to support Dzungar–Qing Wars, 2000 Solon Barga soldiers were selected by Qing commander Jorhai in 1733 to fight against Dzungar and local defence was left with merely 1,100 soldiers. Thus it became extremely important to increase local defense against Russian Cossack. In 1734, the Barga Mongols who had been left under the Khalkha noyans complained of the mistreatment of their lords and the Qing authority selected 2,984 Barga Mongolian soldiers in Khalkha and stationed them with their families in Khölönbuir, Dornod. They became "New Barga", since they arrived after Old Barga. Military Support to Qing dynasty In 1733, 2000 soldiers (mostly Solon Barga soldiers from the forest tribes) were forced to join Dzungar-Qing Wars. They never returned. In 1755, 3000 Barga soldiers were forced to join Dzungar-Qing Wars. They never returned. In 1758, 3000 Barga teenagers were forced to join Dzungar-Qing Wars, since there were not enough adults. They never returned. In 1840, some Barga soldiers (numbers unknown) joined First Opium War, and some of them returned home in 1841. In other occasions, 750~50 Barga soldiers were selected to support Qing dynasty campaigns for around 20 times. In 1901, 800 local Barga soldiers were killed in Chinese Eastern Railway construction. Japanese Occupation Period In 1939, local Barga people were forced to join Soviet–Japanese border conflicts. The unclear border definition between New Barga Left Banner and Dornod (where Barga originally lived) was the major excuse for the start of Battles of Khalkhin Gol. PRC China Period Genetics Derenko et al. (2012) tested blood samples of 149 unrelated Barghuts collected in different localities of Hulun Buir Aimak, Inner Mongolia, China. The mtDNA of the sampled Barghuts belonged predominantly to East Eurasian haplogroups, in particular haplogroup D4 (52/149 = 34.9%), haplogroup C4 (24/149 = 16.1%), and haplogroup G2a (13/149 = 8.7%), with those three clades by themselves accounting for approximately 60% of the entire sample. Their D4 mtDNA is diverse, with the most frequently observed subclades being D4j (TMRCA 16,210 [95% CI 10,600 <-> 21,970] ybp; 14/149 = 9.4% D4j, including 4/149 D4j9, 3/149 D4j3, 3/149 D4j*, 1/149
