arriving via inland waterways. In 1917, the two submarines were sent back to the Baltic for overhaul. In March 1917, Nalim and Skat were removed from service. In August 1917, Feldmarshal General Sheremetev was renamed Keta. In 1918, Kasatka, Makrel and Okun were transferred to the Caspian Sea. In April 1918, Nalim and Skat were re-activated and used against the Soviets. After the Treaty of Brest-Litovsk was signed ending the Russian participation in World War I, they briefly flew the flag of the Ukrainian State before the Germans seized Nalim and Skat. In November 1918, following the Armistice of 11 November 1918 which ended World War I, the British took over the submarines after the German Empire surrendered. The two subs were later scuttled by the British at Sevastopol to prevent their capture by the Soviets during the Russian Civil War. The surviving boats were broken up for scrap in 1922.
