Ptolemy, marching on <a class="linkToPlace" target="_blank" href="/place?placename=Pelusium&groupId=863&placeId=1555">Pelusium</a>, made his first halt at that city,
and after picking up stragglers and serving out rations to his men moved on marching through the desert and skirting Mount Casius and the marshes called <a class="linkToPlace" target="_blank" href="/place?placename=Barathra&groupId=393&placeId=736">Barathra</a>.
Reaching the spot he was bound for on the fifth day he encamped at a distance of fifty stades from <a class="linkToPlace" target="_blank" href="/place?placename=Raphia&groupId=925&placeId=1656">Raphia</a>, which is the first city of <a class="linkToPlace" target="_blank" href="/place?placename=Coele-Syria&groupId=484&placeId=908">Coele-Syria</a> on the Egyptian side after <a class="linkToPlace" target="_blank" href="/place?placename=Rhinocolura&groupId=928&placeId=1661">Rhinocolura</a>.
Antiochus was approaching at the same time with his army, and after reaching <a class="linkToPlace" target="_blank" href="/place?placename=Gaza&groupId=599&placeId=390">Gaza</a> and resting his forces there, continued to advance slowly. Passing <a class="linkToPlace" target="_blank" href="/place?placename=Raphia&groupId=925&placeId=1656">Raphia</a> he encamped by night at a distance of ten stades from the enemy.
At first the two armies continued to remain at this distance from each other,
but after a few days Antiochus, with the object of finding a more suitable position for his camp and at the same time wishing of encourage his troops, encamped so near Ptolemy that the distance between the two camps was not more than five stades.
Skirmishes were now frequent between the watering and foraging parties, and there was occasional interchange of missiles between the cavalry and even the infantry.
