What happened October 1991AD in Croatia

On October 3, the Yugoslav Navy renewed its blockade of the main ports of Croatia.

On October 5, President Tuđman made a speech in which he called upon the whole population to mobilize and defend against "Greater Serbian imperialism" pursued by the Serb-led JNA, Serbian paramilitary formations, and rebel Serb forces.

On 7 October, the Yugoslav air force attacked the main government building in Zagreb, an incident referred to as the bombing of Banski dvori.

The next day, as a previously agreed three-month moratorium on implementation of the declaration of independence expired, the Croatian Parliament severed all remaining ties with Yugoslavia. 8 October is now celebrated as Independence Day in Croatia.

On 15 October after the capture of Cavtat by the JNA, local Serbs led by Aco Apolonio proclaimed the Dubrovnik Republic.

Croatian forces made further advances in the second half of December, including Operation Orkan 91 which was a military offensive undertaken by the Croatian Army (Hrvatska vojska – HV) against the Yugoslav People's Army (Jugoslovenska Narodna Armija – JNA) and SAO Western Slavonia Territorial Defense Forces in the Sava River valley, in the region of Western Slavonia during the Croatian War of Independence. The operation began on 29 October 1991 and ended on 3 January 1992 when a nationwide ceasefire was signed to implement the Vance plan. The offensive was aimed at recapturing the region, in conjunction with two other HV offensives launched against SAO Western Slavonia in the north of the region within days.

Operation Otkos 10 (31 October to 4 November) resulted in Croatia recapturing an area between the Bilogora and Papuk mountains.
