Operation Flash (Serbo-Croatian: Operacija Bljesak/Операција Блесак) was a brief Croatian Army (HV) offensive conducted against forces of the self-declared Republic of Serbian Krajina (RSK) from 1–3 May 1995. The offensive occurred in the later stages of the Croatian War of Independence and was the first major confrontation after ceasefire and economic cooperation agreements were signed between Croatia and the RSK in 1994.
