routes, as opposed to the Egyptian expectations of a repeat of the 1956 war, when the IDF attacked via the central and southern routes) and method (using a combined-force flanking approach, rather than direct tank assaults). Northern (El Arish) Israeli division On 5 June, at 7:50 am, the northernmost Israeli division, consisting of three brigades and commanded by Major General Israel Tal, one of Israel's most prominent armour commanders, crossed the border at two points, opposite Nahal Oz and south of Khan Yunis. They advanced swiftly, holding fire to prolong the element of surprise. Tal's forces assaulted the "Rafah Gap", an stretch containing the shortest of three main routes through the Sinai towards El Qantara and the Suez Canal. The Egyptians had four divisions in the area, backed by minefields, pillboxes, underground bunkers, hidden gun emplacements and trenches. The terrain on either side of the route was impassable. The Israeli plan was to hit the Egyptians at selected key points with concentrated armour. Tal's advance was led by the 7th Armored Brigade under Colonel Shmuel Gonen. The Israeli plan called for the 7th Brigade to outflank Khan Yunis from the north and the 60th Armored Brigade under Colonel Menachem Aviram would advance from the south. The two brigades would link up and surround Khan Yunis, while the paratroopers would take Rafah. Gonen entrusted the breakthrough to a single battalion of his brigade. Initially, the advance was met with light resistance, as Egyptian intelligence had concluded that it was a diversion for the main attack. However, as Gonen's lead battalion advanced, it suddenly came under intense fire and took heavy losses. A second battalion was brought up, but was also pinned down. Meanwhile, the 60th Brigade became bogged down in the sand, while the paratroopers had trouble navigating through the dunes. The Israelis continued to press their attack, and despite heavy losses, cleared the Egyptian positions and reached the Khan Yunis railway junction in a little over four hours. Gonen's brigade then advanced nine miles to Rafah in twin columns. Rafah itself was circumvented, and the Israelis attacked Sheikh Zuweid, to the southwest, which was defended by two brigades. Though inferior in numbers and equipment, the Egyptians were deeply entrenched and camouflaged. The Israelis were pinned down by fierce Egyptian resistance and called in air and artillery support to enable their lead elements to advance. Many Egyptians abandoned their positions after
