were at an unprecedented high. According to declassified documents from the Agranat Commission, Brigadier General Yisrael Lior, Prime Minister Golda Meir's military secretary/attaché, claimed that Mossad knew from Ashraf Marwan that an attack was going to occur under the guise of a military drill a week before it occurred, but the process of passing along the information to the Prime Minister's office failed. On the night of October 5/6, Marwan incorrectly informed Zamir that a joint Syrian-Egyptian attack would take place at sunset. It was this warning in particular, combined with the large number of other warnings, that finally goaded the Israeli High Command into action. Just hours before the attack began, orders went out for a partial call-up of the Israeli reserves. Israeli preparation Prime Minister Golda Meir, Minister of Defense Moshe Dayan and Chief of General Staff David Elazar met at 8:05 am on the morning of Yom Kippur, six hours before the war began. Elazar proposed a mobilization of the entire air force and four armored divisions, or 100,000 to 120,000 troops, while Dayan favored a mobilization of the air force and two armored divisions, or around 70,000 troops. Meir chose Elazar's proposal. Elazar argued in favor of a pre-emptive attack against Syrian airfields at noon, Syrian missiles at 3:00 pm, and Syrian ground forces at 5:00 pm: Prior to the war, Kissinger and Nixon consistently warned Meir that she must not be responsible for initiating a Middle East war, and on October 6, 1973, Kissinger sent a further dispatch discouraging a preemptive strike. Israel was totally dependent on the United States for military resupply and sensitive to anything that might endanger that relationship. At 10:15 am, Meir met with American ambassador Kenneth Keating to inform him that Israel did not intend to preemptively start a war, and asked that American efforts be directed at preventing war. Kissinger urged the Soviets to use their influence to prevent war, contacted Egypt with Israel's message of non-preemption, and sent messages to other Arab governments to enlist their help on the side of moderation. These late efforts were futile. According to Henry Kissinger, had Israel struck first, it would not have received "so much as a nail". Course of the war The war began on October 6, 1973, when the Arab coalition jointly launched a surprise attack against Israel on the Jewish holy day of Yom Kippur, which had occurred
