(Волжская военная флотилия, or Volzhskaya voyennaya flotiliya) and renamed to the Volga-Caspian Military Flotilla (Волжско-Каспийская военная флотилия). On May 1, 1920, the Soviets established the Caspian Fleet, which comprised three auxiliary cruisers, ten torpedo boats, four submarines and other ships. Together with the Caspian Fleet, there was the Red Fleet of the Soviet Azerbaijan, stationed in Baku, as well. Both fleets completed the conquest of the Caspian Sea from the White Army. In July 1920, Caspian and Azerbaijani fleets were combined into the Naval Forces of the Caspian Sea (Морские Силы Каспийского моря, or Morskiye Sily Kaspiyskogo morya) and would later be renamed to the Caspian Flotilla on June 27, 1931. During the Great Patriotic War of 1941–1945, the Caspian Flotilla secured vital sea shipping of army units, military equipment and different cargo, especially during the Battle of Stalingrad and the battle for the Caucasus. (During the war, some of the Lend Lease were shipped to the USSR via the Persian Corridor and the Caspian Sea). During the Cold War the Caspian Flotilla was used to test missile armed ekranoplanes. Post-Soviet era Following the Dissolution of the Soviet Union, the fleet shrank, and the Kazakh contingent was removed to serve as a basis for Kazakhstan's naval service. For several years, Russia continued to lead a joint Turkmen-Russian force based at Astrakhan. Among the Flotilla's units, from 2000, has been a new Naval Infantry brigade, the 77th, based at Kaspiysk. The headquarters and two battalions of the brigade were scheduled to be established by August 1, 2000. It was reported in June 2000 that the new brigade, which had inherited the lineage of the disbanded 77th Guards Motor Rifle Division, formerly with the Northern Fleet, was to have its troops housed in Kaspiysk and Astrakhan and have as many as 195 combat vehicles and one Gepard class frigate sent to it from Chukotka and the Northern Fleet, respectively. The brigade was to have helicopters added to it, according to the June 2000 report. The Brigade's full name was the 77th Detached Guards Moscow-Chernigov Order of Lenin, the Red Banner, Order of Suvorov Marine Brigade. It was disbanded in 2009. The brigade comprised a headquarters at Kaspiysk; the 414th Detached Naval Infantry Battalion (Kaspiysk); the 725th Detached Naval Infantry Battalion (Kaspiysk); the 727th Detached Naval Infantry Battalion (Astrakhan); the 1200th Detached Reconnaissance Battalion (Kaspiysk); the 1408th Independent Howitzer Artillery Battalion; the 1409th
