The 65-meter high Peru?a Dam on the Cetina River was Yugoslavia’s second-largest hydroelectric facility before the country’s breakup with the Croation War beginning in 1991. On January 28, 1993, Serbian/Yugoslav army forces detonate explosives at the dam in an attempt to wipe out Croatian villages and the port city of Omi’. A successful Croation counter-attack allows military engineers to reach the dam and release water on time to prevent it from bursting, saving an estimated twenty- to thirty-thousand civilians. Credit for preventing a dam burst is also given to British Marine Captain Mark Gray, a UN Observer, for opening gates to reduce water levels prior to the attack.
