take by force. Meanwhile, IDF forces took Iraq Suwaydan itself after a fierce battle, losing 6 dead and 14 wounded. From 5 to 7 December, the IDF conducted Operation Assaf to take control of the Western Negev. The main assaults were spearheaded by mechanised forces, while Golani Brigade infantry covered the rear. An Egyptian counterattack was repulsed. The Egyptians planned another counterattack, but it failed after Israeli aerial reconnaissance revealed Egyptian preparations, and the Israelis launched a preemptive strike. About 100 Egyptians were killed, and 5 tanks were destroyed, with the Israelis losing 5 killed and 30 wounded. On 22 December, the IDF launched Operation Horev (also called Operation Ayin). The goal of the operation was to drive all remaining Egyptian forces from the Negev, destroying the Egyptian threat on Israel's southern communities and forcing the Egyptians into a ceasefire. During five days of fighting, the Israelis secured the Western Negev, expelling all Egyptian forces from the area. Israeli forces subsequently launched raids into the Nitzana area, and entered the Sinai Peninsula on 28 December. The IDF captured Umm Katef and Abu Ageila, and advanced north towards Al Arish, with the goal of encircling the entire Egyptian expeditionary force. Israeli forces pulled out of the Sinai on 2 January 1949 following joint British-American pressure and a British threat of military action. IDF forces regrouped at the border with the Gaza Strip. Israeli forces attacked Rafah the following day, and after several days of fighting, Egyptian forces in the Gaza Strip were surrounded. The Egyptians agreed to negotiate a ceasefire on 7 January, and the IDF subsequently pulled out of Gaza. According to Morris, "the inequitable and unfair rules of engagement: the Arabs could launch offensives with impunity, but international interventions always hampered and restrained Israel's counterattacks." On 28 December, the Alexandroni Brigade failed to take the Falluja Pocket, but managed to seize Iraq el-Manshiyeh and temporarily hold it. The Egyptians counterattacked, but were mistaken for a friendly force and allowed to advance, trapping a large number of men. The Israelis lost 87 soldiers. On 5 March, Operation Uvda was launched following nearly a month of reconnaissance, with the goal of securing the Southern Negev from Jordan. The IDF entered and secured the territory, but did not meet significant resistance along the way, as the area was already designated to be part of the Jewish state in the UN Partition Plan,
