1st Battalion of the 260th Regiment near Drežnica, and a company of 1st Battalion of the 259th Regiment, sent from Konjic, was destroyed near Prozor. According to the popular myth, on the eve of the attack, a conference in the 3rd Division HQ was interrupted by the arrival of a courier with a note from Tito (who was in nearby Šćit). The note simply read: "Prozor must fall tonight" (Prozor noćas mora pasti). Historical records and participants' memories are divided on the subject, but the phrase became popular, and entered into everyday speech and pop culture. The offensive continued with the 10th Herzegovina Brigade of the 3rd Partisan Division attacking and routing a company from the 1st Battalion of the 259th Regiment in Rama on 20 February, inflicting losses of 183 killed and 7 captured Italian soldiers. On 22 February, the 5th Proletarian Brigade of the same division captured Ostrožac on Neretva. In the meantime, the 4th Proletarian Brigade from the Right Column captured a further 270 Italians, 140 of which were in the town of Jablanica, which was taken on 22 February. Among the captured were Lieutenant Colonel Pelleroni, commander of the Jablanica garrison, and Colonel Malantonio, Commander of the 259th Regiment. Colonel Malantonio was shot after the Partisans had determined that he was a prominent member of the Fascist Party, and that he had taken part in the Spanish Civil War as an officer in the Italian Corpo Truppe Volontarie. With the fall of Jablanica, Partisans were in control of the entire Neretva valley between Mostar and Ivan Sedlo; only the strategically important town of Konjic was still in Italian hands. The Left Column (1st Proletarian Division) was only partially concentrated, but decided to go ahead with the plan using only two of its brigades. The main objectives on the Sarajevo-Konjic railway line, Ivan sedlo and Raštelica, were defended by the Ustaša Railroad Battalion, and important railroad objects Bradina, Lukač and Brđani were defended by up to a company strong Italian units in strong fortifications. The 1st Proletarian Brigade captured the important mountain pass Ivan Sedlo and Raštelica station on 17 February by a coup de main. The Italian fortifications were overcome on 18 February, after some artillery and mortar fire exchanges, and after an intervention attempt by an armored train from Konjic had been repulsed. In that situation, with no enemy activity from Sarajevo, the 1st Proletarian
