Troops of Montenegro supported the revolt and captured 12 Ottoman soldiers and imprisoned them in Podgorica. The first serious attempt of the Ottoman government to suppress the revolt resulted with the Battle of Deçiq. Terenzio Tocci gathered the Mirdite chieftains on 26 April 1911 in Orosh, proclaimed the independence of Albania, raised the flag of Albania  and established the provisional government. Shefqet Turgut Pasha wanted to meet this threat and returned to the region with 8.000 soldiers. As soon as he reached Shkodër on 11 May, he issued a general proclamation which declared martial law and offered an amnesty for all rebels  if they immediately return to their homes. After Ottoman troops entered the area Tocci fled the empire abandoning his activities. On 14 May, three days after his poclamation, Shefqet Turgut Pasha ordered his troops to seize Dečić, hill that overlooked Tuzi. Sixty Albanian chieftains rejected Turgut Pasha's proclamation on their meeting in Podgorica on 18 May. After almost a month of intense fightings rebels were trapped and their only choices were either to die fighting, to surrender or to flee to Montenegro. Most of the rebels chose to flee to Montenegro which became a base for large number of rebels determined to attack the Ottoman Empire. Ismail Kemal Bey and Tiranli Cemal bey traveled from Italy to Montenegro at the end of May and met the rebels to convince them to adopt the nationalistic agenda which they eventually did. On 12 June Porte prematurely proclaimed that the revolt had ended.
