Brigade lost 33 dead and 40 wounded. Manara and Misgav Am were totally cut off, and Israel's protests at the UN failed to change the situation. On 24 October, the IDF launched Operation Hiram and captured the entire upper Galilee area, driving the ALA back to Lebanon, and ambushing and destroying an entire Syrian battalion. The Israeli force of four infantry brigades was commanded by Moshe Carmel. The entire operation lasted just 60 hours, during which numerous villages were captured, often after locals or Arab forces put up resistance. Arab losses were estimated at 400 dead and 550 taken prisoner, with low Israeli casualties. Some prisoners were reportedly executed by the Israeli forces.

However, invading the West Bank might have brought into the borders of the expanding State of Israel a massive Arab population it could not absorb. The Negev desert was an empty space for expansion, so the main war effort shifted to Negev from early October. Israel decided to destroy or at least drive out the Egyptian expeditionary force since the Egyptian front lines were too vulnerable as permanent borders. On 15 October, the IDF launched Operation Yoav in the northern Negev. Its goal was to drive a wedge between the Egyptian forces along the coast and the Beersheba-Hebron-Jerusalem road and ultimately to conquer the whole Negev. This was a special concern on
