During the war he received four awards, including the Order of St. Vladimir and the Sword of St. George, in battle on Dec. 17, 1916, on the ridge of Poiana-Kiriyak, commanding two and a half hundred and guarding the right flank of the 12th Romanian Infantry Division retreating into the valley of the River Solchya.

On December 30, 1919, Semyonov appointed him an assistant in the position of Marching Ataman of the Far Eastern Cossacks, and on January 30, 1920, the head of the Ussuri group of forces and the Khabarovsk Military District.

Kalmykov became infamous for the number of robberies, murders, and wanton rape and looting committed by his soldiers, which aroused the indignation of many leaders in the White Movement, first among them Admiral Kolchak himself.

Major General William S. Graves, who commanded North-American occupation forces in Siberia, testified that:Semeonoff and Kalmikoff soldiers, under the protection of Japanese troops, were roaming the country like wild animals, killing and robbing the people, and these murders could have been stopped any day Japan wished.

Rozanov was removed from power on January 31, 1920, after which the Provisional Government of the Primorsky Regional Zemstvo Board assumed control in Primorye.

Shortly before, Kalmykov seized 622 kg/1372 lb of gold from the Khabarovsk branch of the State Bank, secretly transferring it as a loan to the Japanese command.

Representatives of the Bolshevik Government in Moscow and the White Regional Zemstvo Board unanimously protested against Kalmykov's division's stay on Chinese territory.

The Officers and all healthy fighters were escorted to Fujin CityFugdin, where on March 8, the Ataman was arrested by the Chinese military authorities together with Major-General N.N.

Kalmykov was charged with the appropriation of 917 kg/2022 lb of gold, the murder of representatives of the International Red Cross - Swede Sven Hedblom and Norwegian Ole Opshaug - near the Pogranichnaya Station, as well as in the shelling of a detachment of Chinese gunboats on the Amur River in October 1919.

On March 21, 1920, General Sukhodolsky died, and Kalmykov and Bezoar were transported to the city of Jilin on April 16, where they were placed in the building of the gendarme.

Although the alibi of consular workers was prepared in advance, the Chinese authorities rejected their explanations and placed soldiers on the premises of the institution.
