This is one of the displays at the Soviet Occupation Museum and it tells some of the story of Spiridon Chavchavadze (1878/1879-1952). He was a Georgian nobleman and cavalry officer who rose to the rank of major general in the Imperial Russian Army. He fought in the Russo-Japanese War and then the First World War, but after the communist takeover in Russia he joined the Georgian underground.
After returning to Georgia, he served in the armed forces of the independent Democratic Republic of Georgia, but after Sovietisation he was briefly imprisoned and joined clandestine resistance work under a cover name. When plans for the August 1924 anti-Soviet uprising matured, he was put forward as a commander-in-chief figure and, after the revolt was crushed, escaped with other insurgents over the border, eventually living for years in exile in France while remaining active in émigré politics.
The Russians gave him promises that he would not be prosecuted if her returned to Georgia, so in 1947, he returned to what he considered to be his home country. That promise was promptly ignored and he was then arrested and sent to a Siberian death camp, dying in 1952. He sounds like one very brave man, I can see why the Russians were scared of him.
