the battle, the Israeli brigades of some 3,000 troops, 180 tanks and 60 artillery pieces faced off against three infantry divisions with large armor components comprising 28,000 Syrian troops, 800 tanks and 600 artillery pieces. In addition, the Syrians deployed two armored divisions from the second day onwards. To fight the opening phase of a possible battle, before reserves arrived, Israeli high command had, conforming to the original plan, allocated a single armored brigade, the 188th, accepting a disparity in tank numbers of eighteen to one. When the warning by King Hussein of an imminent Syrian attack was conveyed, Elazar at first only assigned two additional tank companies from 7th Armored Brigade: "We'll have one hundred tanks against their eight hundred. That ought to be enough". Eventually, his deputy, Israel Tal, ordered the entire 7th Armored Brigade to be brought up. Efforts had been made to improve the Israeli defensive position. The "Purple Line" ran along a series of low dormant volcanic cones, "tels", in the north and deep ravines in the south. It was covered by a continuous tank ditch, bunker complexes and dense minefields. Directly west of this line a series of tank ramps were constructed: earthen platforms on which a Centurion tank could position itself with only its upper turret and gun visible, offering a substantial advantage when duelling the fully exposed enemy tanks. The Syrians began their attack at 14:00 with an airstrike by about a hundred aircraft and a fifty-minute artillery barrage. The two forward infantry brigades, with an organic tank battalion, of each of the three infantry divisions then crossed the cease-fire lines, bypassing United Nations observer posts. They were covered by mobile anti-aircraft batteries, and equipped with bulldozers to fill-in anti-tank ditches, bridge-layer tanks to overcome obstacles and mine-clearance vehicles. These engineering vehicles were priority targets for Israeli tank gunners and took heavy losses, but Syrian infantry at points demolished the tank ditch, allowing their armor to cross. At 14:45, two hundred men from the Syrian 82nd Paratrooper Battalion descended on foot from Mount Hermon and around 17:00 took the Israeli observation base on the southern slope, with its advanced surveillance equipment. A small force dropped by four helicopters simultaneously placed itself on the access road south of the base. Specialised intelligence personnel were captured. Made to believe that Israel had fallen, they disclosed much sensitive information. A first Israeli attempt on October
