World War I

After the destruction of General Samsonov's 2nd Army in the wake of the Battle of Tannenberg, the 10th Army was formed in late August 1914 from reserve units. On 29 August 1914, Vasily Flug was appointed commander of this 10th Army and made a general of the infantry. Despite successful actions in the battles against the 8th German Army and the taking of Suwałki, and because of disagreements with General Nikolai Ruzsky, Vasily Flug was on 23 September 1914 suspended for "dangerous activities" by the command of the army and transferred to the supreme commander. On 4 October 1914, he was appointed to supervise the restoration of the 13th and 15th Army Corps, which had been all but destroyed in Eastern Prussia in August 1914. On 8 July 1915, he was appointed commander of the 2nd Army Corps. He was awarded the Order of St. George 4th degree.

During the Vilnius operation in September 1915, the Germans set out to disengage the troops of the Northern and Western fronts by hitting at the wedge between the 5th and 10th armies, and sending cavalry to the area of Molodechno to operate in the rear of the 10th Army. Part of the 2nd Corps under the general command of General Flug was ordered to counter the enemy's designs. Not only did he withheld the onslaught of the enemy, but he also moved to the offensive. As a result of the energy, courage and skilful leadership shown by General Flug, the German plan came to nothing.

In 1916, the 2nd Corps joined the 7th Army and participated in the South-Western Front offensive in the summer of 1916.

Revolution and Civil War

After the February Revolution, Flug was put on 30 May 1917 in the reserve of officers at the headquarters of the Petrograd Military District. After the October coup, he left for Don. On November 14, 1917, he arrived in Novocherkassk and offered his services to General Mikhail Alekseyev, who had formed the Volunteer Army.

In February 1918, Vasily Flug was sent to Siberia to organize the anti-bolshevik resistance there. He left Novocherkassk on 25 February under the name of Vasily Fadeev. During his mission to Siberia, he helped unify and coordinate the activities of the clandestine officers' organizations in Omsk, Petropavlovsk, Tomsk and Irkutsk. On 29 March 1918, he arrived in Omsk, on 27 April, in Tomsk, on 4 May, in Irkutsk, and on 11 June in Vladivostok. Vasily Flug then travelled to Harbin, where he was a member of the Government of General Horvath from June 1918. On 1–14 December 1918, he temporarily served as commander of the troops in the Amur military region. As of 3 December 1918, he became an assistant High Commissioner in the Far East of General Horvath in the civil area.

At the very end of 1918, Flug arrived in Omsk, where he met Admiral Kolchak. Despite his extensive experience and involvement in the organization of the Anti-Bolshevik resistance in Siberia, there was no place for him in Kolchak's Army. On the instructions of Kolchak, he returned to southern Russia at the disposal of general Anton Denikin. On February 10, 1919, Vasily Flug sailed from Vladivostok on the steamboat Tomsk and on April 6, 1919, arrived in Novorossiysk.

After returning to Southern Russia, Flug was entrusted in May 1919 with carrying out an inspection of all logistical institutions under the authority of the Special Meeting. His main task was the expulsion from the excessively overgrown number of logistical offices compared to officers suitable for combat service. In September 1919, he was appointed an assistant to the military unit of the commander-in-chief and commander of the Kiev region, General Dragomirov. After the loss of Kiev, he retreated to the Crimea. On 8 December 1919 Flug was transferred to the reserve ranks at the headquarters of the Novorossiysk region.

In exile

In 1920, after the Crimea was abandoned by the White Russian troops, Flug left for Yugoslavia. From 1922 he served in the Yugoslav Military Ministry (Varaždin). He was actively involved in the activities of the Russian All-Military Union. In 1930, Flug became acting chief of the 4th Division of the Russian All-Military Union (Yugoslavia), and at the same time until March 1932, he served as chairman of the district government of the Russian staff officers in the 4th Division of the Russian All-Military Union.

During World War II Flug served in the Russian Corps. After the war ended, he moved to the United States. He was a member of the Society of Great War veterans. He was a permanent employee of the magazine Watch and Bulletin of Military Knowledge. Flug died in San Francisco.^[2][3]
