Six-Day War
On the Sinai front, Egyptian troops were retreating towards the Mitla and Gidi Passes in the hope of crossing the Suez Canal and getting to safety on the Egyptian mainland. With the Israeli forces getting closer to the Suez Canal, Amer gave the order that all Egyptian troops must protect the Suez Canal from the west and that all passes to and bridges over the canal must be destroyed. However, that meant that retreating Egyptian troops from the Sinai could no longer cross the canal and get to safety. With the Israeli forces so close, Nasser agreed to a ceasefire.
