Guards Brigade began an eastward attack in the Mala Kapela area in the morning, meeting heavy resistance from the ARSK 70th Infantry Brigade. The rest of the 1st Guards joined in around midnight. The 133rd Home Guard Regiment attacked east of Otočac, towards Vrhovine, attempting to encircle the ARSK 50th Infantry Brigade and elements of the ARSK 103rd Infantry Brigade in a pincer movement. Even though the regiment advanced, it failed to achieve its objective for the day. On the regiment's right flank, the HV 128th Brigade advanced together with the 3rd Battalion of the 8th Home Guard Regiment and cut through the Vrhovine–Korenica road. The rest of the 9th Guards Brigade, the bulk of the HV 118th Home Guard Regiment and the 111th Infantry Brigade advanced east from Gospić and Lički Osik, coming up against very strong resistance from the ARSK 18th Infantry Brigade. As a result of these setbacks, the Gospić Corps ended the day short of the objectives it had been given. Sector North In the Ogulin area of the HV Karlovac Corps AOR, the 99th Brigade, reinforced by the 143rd Home Guard Regiment's Saborsko Company, moved towards Plaški at 5 a.m., but the force was stopped and turned back in disarray by 6 p.m. The 143rd Home Guard Regiment advanced from Josipdol towards Plaški, encountering minefields and strong ARSK resistance. Its elements connected with the 14th Home Guard Regiment, advancing through Barilović towards Slunj. Near the city of Karlovac, the 137th Home Guard Regiment deployed four reconnaissance groups around midnight of 3–4 August, followed by artillery preparation and crossing of the Korana River at 5 a.m. The advance was fiercely resisted by the ARSK 13th Infantry Brigade, but the bridgehead was stable by the end of the day. The 110th Home Guard Regiment, reinforced by a company of the 137th Home Guard Regiment, advanced east to the road leading south from Karlovac to Vojnić and Slunj, where it met heavy resistance and suffered more casualties to landmines, demoralizing the unit and preventing its further advance. In addition, the attached company of the 137th Home Guard Regiment and the 104th Brigade failed to secure the regiment's flanks. The 104th Brigade tried to cross the Kupa River at 5 a.m., but failed and fell back to its starting position by 8 a.m., at which time it was shifted to the bridgehead established by the 110th Home Guard Regiment.
