Following Operation Yoav, the Egyptian Army tried to stabilize a defensive line between its two arms of controlled territory in the Negev, along the Beer Sheva-Gaza road.
With international peace-efforts intensifying, both sides felt that the war was drawing to a close, and such a strong defensive line would help Egypt claim the majority of western and southern Negev, which included some Israeli settlements.
The main assaults were carried out by the mechanized forces, while Golani's infantry came in the second wave to cleanse and defend newly captured positions.
Phase 1, went according to plan, with IDF forces capturing three important Egyptian positions without major combat or casualties, on the operation's first day (December 5, 1948).
However, the Israelis met stronger resistance at another position (which was not captured) and were forced to stop their advance when they hit a minefield in another location.
