At around 13:00, a recon group from 2nd Division discovered around 75 tanks concentrating north east of the bridgehead. Ten minutes later the Egyptians intercepted a radio signal in Hebrew. Nir was informing his command that he was ready to attack within twenty minutes. With little time left, Abu Sa'ada decided to take a risky move. Estimating, correctly, that the attack would come be directed between his two forward brigades, the weakest point in his lines, Abu Sa'ada planned to draw Israeli forces into his bridgehead to within three kilometers of the canal before engaging them from all sides, committing all his anti-tank reserves. At 13:30, the attack was carried out by Amir and Nir's brigades. A lack of coordination and communication difficulties between both brigades hampered the attack. Nir's two battalions attacked at the same time in two echelons. The Egyptians allowed the Israelis to advance, then encircled them. When the attackers entered the prepared killing zone, Egyptian armor of the 24th Brigade opened fire on the advancing tanks, complemented by infantry anti-tank weapons on either flank of the Israeli forces, while tank hunting detachments attacked from the rear. Within just 13 minutes, most of the Israeli force was destroyed—the Egyptians destroyed over 50 tanks and captured eight intact. Among the captured were Lieutenant Colonel Asaf Yaguri, a battalion commander, whose unit lost 32 killed. By the end of the attack Nir had just four operational tanks remaining, including his own. Gabi Amir's battalion, attacking to Nir's right, was forced to halt his advance after encountering stiff resistance. Amir requested air support several times, but did not receive any.
