On 27 June 1905, Potemkin was at gunnery practice near Tendra Island off the Ukrainian coast when many enlisted men refused to eat the borscht made from rotten meat partially infested with maggots. The uprising was triggered when Ippolit Giliarovsky, the ship's second in command, allegedly threatened to shoot crew members for their refusal. He summoned the ship's marine guards as well as a tarpaulin to protect the ship's deck from any blood in an attempt to intimidate the crew. Giliarovsky was killed after he mortally wounded Grigory Vakulinchuk, one of the mutiny's leaders. The mutineers killed seven of the Potemkin's eighteen officers, including Captain Evgeny Golikov, and captured the torpedo boat Ismail (No. 627). They organized a ship's committee of 25 sailors, led by Afanasi Matushenko, to run the battleship.
The movie is on youtube, huh. One of the great classic silent films. If you have not seen the movie, it deserves a watch.
