1973 Yom Kippur War
Three years of relative calm along the borders were shattered on Yom Kippur (Day of Atonement), the holiest day of the Jewish year, when Egypt and Syria launched a coordinated surprise assault against Israel (6 October 1973), with the Egyptian army crossing the Suez Canal and Syrian troops penetrating the Golan Heights.

During the next three weeks, the Israel Defense Forces turned the tide of battle and repulsed the attackers, crossing the Suez Canal into Egypt and advancing to within 20 miles (32 km.) of the Syrian capital, Damascus.
