Starting at sunrise on October 20, the Israeli Air Force launched aerial attacks for the duration of the day, targeting Ismailia, the nearby al-Galaa' army base, and Jebel Mariam. Close air support was also provided to advancing ground forces. Israeli aircraft employed ordnance fitted with time fuses, as well as napalm to demoralize Egyptian troops. Shazly left Ismailia that evening, returning to Cairo where he presented a grim evaluation of the military situation to GHQ. His recommendation to withdraw armored forces to counter the Israeli threat on the west bank created a serious command crisis, and ultimately no withdrawal took place.
