guma (, "Pskhu"; , "Ps'hwy"; , "Pskhu") is a village in the Sukhumi district of Abkhazia, a disputed region on the Black Sea coast. Its population was about 150 (as of 2005) with ethnic Russians constituting a majority. The village is situated in the eponymous valley between the Greater Caucasus and Bzyb ranges. The river Bzyb and several of its tributaries flow near the village. The valley was inhabited by the Abazins tribe which was one of the last peoples of the Caucasus to be conquered by Russia. After their subjection in 1864 almost all of them escaped to Turkey; many perished at the Black sea coast from hunger and malaria, during the transportation to Ottoman Empire. Pskhu was the only settlement in the Transcaucasia to be occupied by Wehrmacht during the Battle of the Caucasus of World War II in the autumn of 1942.
