Excerpts from Books and Wikipedia
"Syrian forces pushed into the Golan Heights, while the Egyptians stormed across the Suez Canal into Sinai. . . . They were to be saved in part by poor coordination between their enemies, a massive airlift of US equipment, and the prompt supply of US intelligence on the enemy dispositions. . . . A cease-fire favorable to Israel was agreed upon less than three weeks after the first shot. . . . The Organization of Petroleum Exporting Countries (OPEC) imposed crippling sanctions on the West, convincing Europeans of the need for peace." [Furtado: 1001 Days] "The war began when the Arab coalition launched a joint surprise attack on Israeli positions in the Israeli-occupied territories on Yom Kippur, the holiest day in Judaism, which also occurred that year during the Muslim holy month of Ramadan. Egyptian and Syrian forces crossed ceasefire lines to enter the Sinai Peninsula and the Golan Heights respectively. Both the United States and the Soviet Union initiated massive resupply efforts to their respective allies during the war, and this led to a near-confrontation between the two nuclear superpowers."
