On August 1, Jaish broke through the Syrian army‘s first line of defense. The fighters were then blocked for a few days at the Artillery School, transformed into a veritable citadel, but several suicide attacks eventually allowed them to break through. Rebels within eastern Aleppo, belonging to the „Fatah Halab operations room,“ contributed minimally to the attack, although on August 2 they successfully blew up a tunnel under the Ramouseh district, which allowed them to invade the north of Ramouseh, taking the Syrian army from behind.
