The Second Battle of Gaza was fought on 17–19 April 1917, following the defeat of the Egyptian Expeditionary Force (EEF) at the First Battle of Gaza in March, during the Sinai and Palestine Campaign of the First World War. Gaza was defended by the strongly entrenched Ottoman Army garrison, which had been reinforced after the first battle by substantial forces. They manned the town's defences and a line of strong redoubts which extended eastwards along the road from Gaza to Beersheba. The defenders were attacked by the Eastern Force's three infantry divisions, supported by two mounted divisions, but the strength of the defenders, their entrenchments & supporting artillery decimated the attackers.
