Sinai Desert 1200 - 6pm
Throughout the afternoon I\DF 162nd Division remained under very heavy Egyptian pressure. Following th fall of Ishmaila East Egyptian armoured forces pushed on towards El Tasa and the Giddi/Mitla passes where th IDF had positioned their main defensive positions. IDF M60s and Tow Missiles inflicted heavy losses on the Egyptians but the latter's superior numbers and concentrated attacks (unlike the failed October 14 offensive) started to tell as the afternoon wore on. By 4pm there was heavy fighting at El Tasa itself and the passes were under heavy Egyptian shellfire. By 4.45pm the passes were under direct and heavy ground attack/
At 5pm Adan telephoned Moshe Dayan to request the committal of reserves. There were none to send. Dayan was by this time aware of the three Egyptian divisions crossing the Suez. Northern Command still had its' hands full dealing with the Arab offensive there although reports were good from that quarter. The movement of the Egyptian reserves simply had to be stopped and now there was only on way to do it
After a brief meeting between Dayan and Golda Meir the order to initiate Operation Sampson was given at 5.22pm
