FACT On October 6, 1973 — Yom Kippur, the holiest day in the Jewish calendar — Egypt and Syria opened a coordinated surprise attack against Israel. The equivalent of the total forces of NATO in Europe were mobilized on Israel's borders (Chaim Herzog, The Arab-Israeli Wars, NY: Random House, 1984, p. 230.).1 On the Golan Heights, approximately 180 Israeli tanks faced an onslaught of 1,400 Syrian tanks. Along the Suez Canal, fewer than 500 Israeli defenders were attacked by 80,000 Egyptians.
Thrown onto the defensive during the first two days of fighting, Israel mobilized its reserves and eventually repulsed the invaders and carried the war deep into Syria and Egypt. The Arab states were swiftly resupplied by sea and air from the Soviet Union, which rejected U.S. efforts to work toward an immediate ceasefire. As a result, the United States belatedly began its own airlift to Israel. Two weeks later, Egypt was saved from a disastrous defeat by the UN Security Council, which had failed to act while the tide was in the Arabs' favor.
The Soviet Union showed no interest in initiating peacemaking efforts while it looked like the Arabs might win. The same was true for UN Secretary-General Kurt Waldheim.
On October 22, the Security Council adopted Resolution 338 calling for "all parties to the present fighting to cease all firing and terminate all military activity immediately." The vote came on the day that Israeli forces cut off and isolated the Egyptian Third Army and were in a position to destroy it (Herzog, p. 280).
Despite the Israel Defense Forces' ultimate success on the battlefield, the war was considered a diplomatic and military failure. A total of 2,688 Israeli soldiers were killed.
