Army assault on the northern villages
On 16 February, a large military armored convoy arrived in Aleppo, as reinforcements from Hama, to complete the siege of the city. The next morning, government forces launched an offensive from Sifat. The battle started after hundreds of government fighters infiltrated the three villages of Bashkuwi, Ratian and Hardatain before dawn and encircled rebel positions in them. At 06:00 hours, the fighting started and in less than half an hour the Army and NDF captured Hardatain, while resistance continued in the other two villages.

At this point, the rebels launched a counter-attack to recapture the ground they lost and Hardatain was contested once again, while clashes continued near Ratian. The initial advance brought government troops to within four kilometers of the government-held towns of Nubl and Al-Zahraa, which had been besieged by rebel forces for almost two years. In the evening, a group of 80 soldiers managed to reach the two towns. The offensive aimed to completely surround Aleppo within a week.
