The Yom Kippur War (1973)

Following Egypt's defeat in the 1967 war, President Gamal Abdel Nasser died in September 1970. His successor, Anwar Sadat, pursued diplomatic efforts to regain the Sinai Peninsula but failed to make progress. By 1972, Sadat concluded that military action was necessary to break the political stalemate. Egypt and Syria began secret joint planning for a coordinated surprise attack. Sadat expelled Soviet military advisors from Egypt in July 1972 to demonstrate his independence.

On Yom Kippur, the holiest day in Judaism, Egypt and Syria launched a coordinated surprise attack at 2:00 PM. Egyptian forces crossed the Suez Canal at multiple points, breaching the Israeli Bar-Lev Line of fortifications. Using high-pressure water cannons, bridging equipment, and anti-aircraft missiles, the Egyptians established five bridgeheads on the canal's eastern bank. The attack achieved complete tactical surprise.

Simultaneously with the Egyptian attack, Syrian forces launched a massive armored assault on the Israeli-held Golan Heights with approximately 1,400 tanks. Syrian forces initially overwhelmed the thinly manned Israeli defensive line, advancing deep into the plateau. A small Israeli force, outnumbered roughly 10 to 1, held out in desperate defensive battles at positions like the "Valley of Tears." Israeli reservists were rushed to the front.

After three days of defensive fighting, Israeli forces regrouped and launched a counteroffensive on the Golan Heights. By October 10, Israel had pushed Syrian forces back across the 1967 ceasefire line. Israeli forces continued advancing into Syrian territory, coming within 40 kilometers (25 miles) of Damascus, bringing the Syrian capital within artillery range. Iraq and Jordan sent expeditionary forces to support Syria but failed to reverse the Israeli advance.

After establishing bridgeheads on the east bank of the Suez Canal, Egypt launched a major armored offensive on October 14 to relieve pressure on Syria. The Israeli Defense Forces, now fully mobilized, repelled the Egyptian advance in the costly Battle of Chinese Farm. Egypt lost over 250 tanks in a single day. This failure marked the turning point in the Sinai front.

Israeli forces under General Ariel Sharon launched a counter-crossing of the Suez Canal at Deversoir, north of the Great Bitter Lake. Israeli engineers established a bridgehead on the canal's western bank, and by the following days, an entire Israeli division had crossed into mainland Egypt. This maneuver threatened to encircle the Egyptian Third Army and brought Israeli forces within 100 kilometers (60 miles) of Cairo.

Arab members of OPEC, led by Saudi Arabia, declared an oil embargo against countries supporting Israel, primarily the United States and several European nations. The embargo caused oil prices to quadruple from roughly $3 to $12 per barrel and triggered a global energy crisis. Gasoline shortages, long lines at filling stations, and economic recession affected Western economies. The crisis reshaped global energy policy and highlighted the strategic power of oil-producing states.

The United States launched a major airlift of military supplies to Israel (Operation Nickel Grass) on October 12, while the Soviet Union resupplied Egypt and Syria. As the war tilted toward Israel, the Soviet Union threatened intervention to save the Egyptian Third Army from destruction. The US raised its nuclear alert level to DEFCON 3 on October 25, one of the most serious Cold War confrontations. The superpowers jointly pressed for a ceasefire.

UN Security Council Resolution 338, passed on October 22, called for a ceasefire. After several days of continued fighting and superpower pressure, the ceasefire took full effect on October 25. At the end of hostilities, Israel held territory on the western bank of the Suez Canal and had the Egyptian Third Army encircled. Egypt held a 1,200 square kilometer (460 square mile) strip on the canal's eastern bank. Both sides claimed victory.

The Yom Kippur War had far-reaching consequences. The perception of Israeli invincibility was shattered, prompting a reassessment of Israeli defense doctrine. The war discredited the "Three Noes" approach of the Arab states. Sadat's prestige enabled him to pursue a peace initiative, culminating in the Camp David Accords (1978) and the Egypt-Israel Peace Treaty (March 26, 1979), in which Israel returned the Sinai Peninsula to Egypt in exchange for normalized relations. The oil crisis transformed the global economy and heightened Western focus on Middle Eastern energy security.
