However, on December 21, 1991 for the first time in the war Istria was under attack. The Serbian Forces attacked the airport near the city of Vrsar, situated in the south-western of the peninsula between the city of Poreč and Rovinj, with two MiG-21 and two Galeb G-2. Afterwards, Yugoslav airplanes carpet bombed Vrsar's "Crljenka" airport, resulting in two deaths. Mediated by foreign diplomats, ceasefires were frequently signed and frequently broken. Croatia lost much territory, but expanded the Croatian Army from the seven brigades it had at the time of the first ceasefire to 60 brigades and 37 independent battalions by December 31, 1991.
