In November 26, the forces of the Khilafah stunned the whole region. It seized the city of Butig.
They raised the Black banners in only a few hours, by far the largest city it controlled from Filipino soldiers who dropped their weapons and fled.
So stunned had president Duterte been by the avalanche of shame which had been upon him.
But the 49th Infantry Battalion fights back against the so called "Maute Group" during battles to take back the city.
After one week of battles, it recaptured most of the city in house-to-house search operations.
Taghoût Duterte visited injured soldiers in Lanao del Sur province. Many soldiers died while fighting for the Filipino flag.
Many homes, shops, mosques belonging to Muslims were marked and a school was destroyed during heavy battles.
