Israel an additional 55 dead and 79 wounded. An unknown number of Syrians were also killed and some were taken prisoner. An IDF D9 bulldozer supported by infantry forced its way to the peak. An Israeli paratroop force landing by helicopter took the corresponding Syrian Hermon outposts on the mountain, killing more than a dozen Syrians while losing one dead and four wounded. Seven Syrian MiGs and two Syrian helicopters carrying reinforcements were shot down as they attempted to intercede. Northern front de-escalation On October 22, the United Nations imposed a ceasefire, at the acquiescence of both Israel and Egypt, dividing the Syrian General Staff over whether to continue the war. Ultimately, Syrian President Hafez al-Assad decided to de-escalate, and on October 23 Syria announced that it had accepted the ceasefire, while the Iraqi government ordered its forces home.
