The Southern Palestine offensive, employing manoeuvre warfare, began on 31 October 1917, with the Battle of Beersheba, during the Sinai and Palestine Campaign, of World War I. After the capture of Beersheba, by the Egyptian Expeditionary Force (EEF), the Gaza to Beersheba line became increasingly weakened and, seven days later, the EEF successfully forced the Ottoman Turkish Empire's Seventh and Eighth Armies to withdraw. During the following seven days of pursuit, the Turkish forces were pushed back to Jaffa. There followed three weeks of hard fighting in the Judean Hills before Jerusalem was captured on 9 December 1917. During five and a half weeks of almost continuous offensive operations, the EEF captured 47.5 miles (76.4 km) of territory.
