But England had already begun to dread anything which could increase either the possessions or the influence of this formidable power.

Above all, she was determined that the Ottoman Empire should remain intact, and that the Greek navy, beginning to be formidable, must be destroyed.

With these objects in view, negotiations with Ali Pacha were resumed.

The latter was still smarting under his recent disappointment, and to all overtures answered only, "Parga! I must have Parga."-- And the English were compelled to yield it! Trusting to the word of General Campbell, who had formally promised, on its surrender, that Parga should be classed along with the seven Ionian Isles; its grateful inhabitants were enjoying a delicious rest after the storm, when a letter from the Lord High Commissioner, addressed to Lieutenant-Colonel de Bosset, undeceived them, and gave warning of the evils which were to burst on the unhappy town.
On the 25th of March, 1817, notwithstanding the solemn promise made to the Parganiotes, when they admitted the British troops, that they should always be on the same footing as the Ionian Isles, a treaty was signed at Constantinople by the British Plenipotentiary, which stipulated the complete and stipulated cession of Parga and all its territory to the Ottoman Empire.

Soon there arrived at Janina Sir John Cartwright, the English Consul at Patras, to arrange for the sale of the lands of the Parganiotes and discuss the conditions of their emigration.
