Omar Pasha arrived on the 9th of April, and on the 11th a body of 2,000 insurgents came down to the heights of Boutzounaria, and attacked the guard of the aqueduct, to show his Highness, apparently, that they were not discouraged. They were driven back with the loss of three killed, the plan of attack having been betrayed by a miller in the neighborhood, and the troops been reinforced in the night before the appointed day. At the same time, a more decidedly offensive strategy seemed to be adopted by the whole insurrection, owing to the new material brought over by the _Arkadi_, and in several places combats of comparative importance took place. The insurgent chiefs made no concealment of their satisfaction at the change in the command, fearing the wiles and personal influence of Mustapha more than all the artillery and discipline of the Generalissimo. Omar had landed with great pomp and circumstance--horses and guns, cavalry and a staff, new and splendid uniforms. Amongst the others I paid my respects to the new victim, and found him, to my surprise, a weak, conceited, bombastic old man. He assured me that his plan and appliances were so complete and irresistible that within two weeks from the time he set out the insurrection would be crushed. I ventured to suggest that he would find on getting into the interior that the work was much more difficult than he imagined, and that the neglect of the Porte to construct good roads when they had command of the island made their work very difficult. He replied that it could not be more difficult than Montenegro, and he had conquered that, etc. I left him with much less apprehension for the success of the campaign than I had previously entertained. He was a strong contrast to the quiet, concentrated, _rusé_ Mustapha.
