Hayk Bzhishkian (, Persian هایک پزشکیان, Russian: Гайк Бжишкян, also known as Guy Dmitrievich Guy, Gai Dmitrievich Gai (Гай Дмитриевич Гай), Gaya Gai (Гая Гай), or Bzhishkyan, – 11 December 1937), was a Soviet military commander of Armenian origin who fought in the Russian Civil War and Polish-Soviet War. Biography Bzhishkian was born in Tabriz, Iran, to a family of teachers. His mother was Persian and his father was an Armenian socialist (a member of the Armenian Social Democrat Hnchakian Party) who had taken refuge from the tsarist authorities in Persia during the 1880s. He returned to Russia in his teens and was an activist and journalist in Tiflis, where he studied at the Armenian Theological Seminary. He joined the Russian Social Democratic Labor Party in 1904 and spent five years in jail for revolutionary activities before he was drafted in 1914. Because of his background, Gai was assigned to the Russo-Ottoman front, where his repeated acts of bravery under fire earned him the rank of stabs-kapitan, the Cross of St. George (3rd and 4th class), and the Order of St. Anna, all awarded by General Nikolai Yudenich. Captured by the Ottomans, he escaped and returned to Russia badly wounded on the eve of the February Revolution. During World War I, Bzhishkian rose to the rank of captain. Gai, as he came to be known, became a Bolshevik before the October Revolution. (Lincoln, p. 413) He became a military commander in 1918, when he fought against the Czech Legion ("White Czechs") and the Orenburg Cossacks of ataman Alexander Dutov. During the Polish–Soviet War of 1920, he helped Mikhail Tukhachevsky drive the Poles back to Warsaw. Gai was appointed commander of the III Cavalry Corps ("Kavkor"), attached to the Fourth Army, and consisting of the 10th Division (N. D. Tomin) and the 15th (Kuban) Division (V. I. Matuzenko), with the 164th Rifle Brigade in support. In Tukhachevsky's plan, the role assigned to the Kavkor was "of the utmost importance". It was to operate on the extreme right wing of the Soviet advance and turn the flank of the Polish defence lines, thus allowing them to be rolled up by the attacking armies. The Kavkor advanced rapidly, taking Vilnius on July 14, Grodno (where the Red cavalry encountered tanks for the first time) on July 22, reaching the Vistula in the second week of August, and cutting the crucial Warsaw-Gdańsk railway.
