because the officers were poor leaders and treated their soldiers badly; often officers would retreat from danger, leaving their men confused and ineffective. The Israelis also had the upper hand during close combat that took place in the numerous Syrian bunkers along the Golan Heights, as they were armed with the Uzi, a submachine gun designed for close combat, while Syrian soldiers were armed with the heavier AK-47 assault rifle, designed for combat in more open areas. Israeli attack: first day (9 June) On the morning of 9 June, Israeli jets began carrying out dozens of sorties against Syrian positions from Mount Hermon to Tawfiq, using rockets salvaged from captured Egyptian stocks. The airstrikes knocked out artillery batteries and storehouses and forced transport columns off the roads. The Syrians suffered heavy casualties and a drop in morale, with a number of senior officers and troops deserting. The attacks also provided time as Israeli forces cleared paths through Syrian minefields. However, the airstrikes did not seriously damage the Syrians' bunkers and trench systems, and the bulk of Syrian forces on the Golan remained in their positions. About two hours after the airstrikes began, the 8th Armored Brigade, led by Colonel Albert Mandler, advanced into the Golan Heights from Givat HaEm. Its advance was spearheaded by Engineering Corps sappers and eight bulldozers, which cleared away barbed wire and mines. As they advanced, the force came under fire, and five bulldozers were immediately hit. The Israeli tanks, with their manoeuvrability sharply reduced by the terrain, advanced slowly under fire toward the fortified village of Sir al-Dib, with their ultimate objective being the fortress at Qala. Israeli casualties steadily mounted. Part of the attacking force lost its way and emerged opposite Za'ura, a redoubt manned by Syrian reservists. With the situation critical, Colonel Mandler ordered simultaneous assaults on Za'ura and Qala. Heavy and confused fighting followed, with Israeli and Syrian tanks struggling around obstacles and firing at extremely short ranges. Mandler recalled that "the Syrians fought well and bloodied us. We beat them only by crushing them under our treads and by blasting them with our cannons at very short range, from 100 to 500 meters." The first three Israeli tanks to enter Qala were stopped by a Syrian bazooka team, and a relief column of seven Syrian tanks arrived to repel the attackers. The Israelis took heavy fire from the houses, but could
