The next plan for the Sicilian is - Operation Zacinto -, the plans is that of secure the main city and village in Basilicata for then attack the city of Potenza and from there march info the Puglia, but this wasn't easy as for the presence of mechanized and of anti-tank divisions, but the Neapolitans still use the pre-war M47 Patton, a medium and obstoete tank, instead the Sicilians use the Leopard tank, a more advanced and modern tank, the Sicilian crossed the border on the 30th of November, from there they liberate cities and villages with the help of the local resistance, the army arrive in the city of Potenza the 5th December, and took one week for clear the city from hostile presence, they set the HQ there and declare Potenza the first free city in south Italy, from there the Sicilian forces secure the border between Campania and Basilicata, as Neapolitan units try to invade the lost land, but they was repelled by the Sicilians, even if some Sicilian unit was captured and bring at Naples as a reward of war. After their showing in Naples the PoWs was bring in the Gran Sasso Camp, a prisoner camp in Abruzzo, many of this prisoners would suffer for the cold temperature, the poor condition of the camp and of the brutality of the guards.
With the victory of Potenza the army advance in direction of Matera, liberating most of the region from the Neapolitan presence, but some fight happened with local Neapolitan loyalist, in one week of march the Sicilian arrive at Matera in good condition, as fresh Cyrenaican troops arrive in Basilicata for reinforce the already present forces, when the Sicilian forces arrive in Matera the city was well defence by the Neapolitan Army, the Sicilian Army would engage a great battle outside the city for try to enter it, but with the fresh reinforcement and the tanker division the Neapolitan front crumble and the Sicilian could finally enter in the city, but when they was in the centre of the city they found the city desert and abandoned, but it wasn't like the Sicilians thinking, it was a trap, many enemy troops was hiding in roofs and towers sniping the Sicilian from distance, so with this confuse scenario the Sicilian lost many men then in the first battle, when the Sicilian finally take the city, this to the armed divisions, found most of the inhabitants in the old part of the city, seeking a shelter for the battle, many of the citizens was without food and water for several days and they was save by the Sicilian Red Cross and by the Army, the Neapolitan also leave many equipment to the enemy, mainly rifles and pistols but in majority grenades, mines and rocket launchers, with this victory the Sicilians decide to maintain the line of the front between Puglia and Basilicata and rest, their next plan will be that of take Puglia and secure the south-east, but the chief of staff for don't lost valuable resources and for don't be stocked in the winter decide to do the operation in January, as the troops would rest and recover from the fight.
During the Christmas period neither one of the two sides conduct operations or attacks, as they know that it was Christmas and soldiers wouldn't fight in that day, and also for the speech do by the Pope during the Christmas night, as "Implore no fight at least during the day that Christ was born."
