After the June 1967 War, Israel holds all of Sinai and is ensconced in a series of bunkers along the east side of the Suez Canal. Egypt’s President Nasser launches air and artillery strikes, and Israel replies with heavy fighting between the sides, continuing until the cease fire is achieved. Shortly after the cease-fire, Egypt violates it by populating their side of the canal with surface to air missile batteries. In addition to Egyptian and Israeli casualties, Soviet military personnel and pilots are killed while fighting for Egypt. The Russian pilots are shot down by Israelis in aerial combat.
