 Tensions remained high throughout the process and the JNA made contingency plans to break through from Knin to Šibenik and Split and relieve the siege of its forces there—these plans were codenamed Operation Coast-91 ("Operacija Obala-91") and Operation Hurricane-91 ("Operacija Orkan-91") respectively.Amid international pressure on Croatia to end the siege of the JNA garrison in Zagreb, Croatian authorities and the JNA signed an agreement on 22 November to evacuate all remaining JNA forces from Croatia.The agreement was signed in Zagreb, by HV Colonel Imra Agotić and Lieutenant Colonel General Andrija Rašeta in presence of the ECMM monitors.
