4,000 Turks on foot with 9,000 Arabs on horseback set out with twelve cannons and two motars to besiege a fortress named Giroel, in which the pretender to this crown should have taken shelter. It was taken by ault on the 25th, after an obstinate defense, but many of the besieged found an opportunity, through the negligence of the enemy, to make their escape with their wives and children. All that were left were macred without distinction. A small quantity of provisions and effects were found in the place, which the Bey gave to the Turks in his service for their encouragement. The unfortunate pretender reteated, with some horses, to the mountains of Solette, and was received with open arms, by the inhabitants of about 160 villages, surrounded by those mountains whose prodigious height renders them almost inaccessible. Though those people seem willing to take up arms in his favour against the Bey, their sovereign, it is thought the latter will be able to reduce them, as he has gained the good-will of the Turkish soldiery by his largess and his generous disposition so opposite to the avaricious temper of his predecessors.
