Over the next three days, the JNA made slow progress. Its artillery attacked Srđ Hill, the Fort Imperial and Žarkovica on 2 October. The next day, the JNA shelled Dubrovnik's Belvedere Hotel, where a ZNG defence post was located, and the Yugoslav Air Force bombarded the city's Argentina Hotel. On 4 October, the JNA 2nd Corps captured Slano in Dubrovačko Primorje, interdicting the Adriatic Highway there and isolating Dubrovnik from the rest of Croatia. On 5 October, the Ploče district of Dubrovnik was shelled, followed by a Yugoslav Air Force strike on the Fort Imperial the next day.
