This video seems to be from the initial response from Azerbaijan and is several days old. Thats also when the Azeris took most of the casualties. They are right, taking Madaghis directly like that initially was a mistake while it was surrounded on three sides by tall peaks. Azeris pounded the hills with artillery but the Armenians were well dug in, they had decades to prepare their defences. Shortly after that, the Azeris began to successfully jam the Armenians and then the drones wrecked havoc on those mountain peaks. The Azeris now control those peaks where we can see the Armenians firing on the approaching Azeris. Now Madaghis and the neighbouring Talish are firmly in hands of the Azeris.
