or rivers. Among the former are the present-day Caspian Flotilla, the early-20th-century Satakundskaya Flotilla, or the Aral Flotilla of the 1850s; among the latter, the Don Military Flotilla (which was created several times over more than 200 years), the Dnieper Flotilla (also extant in the 18th and 20th centuries), the Red Volga Flotilla, which participated in the Kazan Operation during the Russian Civil War, and the Danube Flotilla. In the 18th century, the term also applied to the comparatively small fleets operating on those seas where Russia did not have much naval presence yet, e.g. the Okhotsk Flotilla. Non-military usage The word flotilla has also been used at times to refer to a small fleet of vessels, commercial or otherwise. There is also such a thing as a "flotilla holiday", which is a group of chartered yachts that set sail together on the same route.
