As the troops of the Egyptian Expeditionary Force (EEF) began to concentrate in preparation for their attacks, they left their camps standing to deceive German and Ottoman aerial reconnaissances. The EEF assumed their opponents thought there were still six infantry divisions in the Gaza area and one in the eastern sector towards Beersheba. However, according to Falls, "is evidence that the [Yildirim Army Group were fairly accurately informed of the British dispositions." On 28 October, they knew the camps at Khan Yunis and Rafa were empty and accurately placed three infantry divisions east of the Wadi Ghuzzee with a fourth, the 10th (Irish) Division approaching the wadi. They estimated more cavalry at Asluj and Khalasa than was actually there.
